Why Spitfire








Consider some of the following and compare.


At Spitfire trailers we have introduced some of the greatest advancement and innovation seen in boat trailers in decades.


For many years we built trailers for trailer companies... then only a couple short years ago,  we decided that the public needed a better product at a fairer price.



We believed we could build an aluminium trailer for the price of a quality galvanised steel trailer.


We introduced previously unseen practices like independent vehicle engineer certification of each model, toughened T6 Grade aluminium rather than mill finished T4 and... believe it or not,  anodised aluminium.


With 36 years manufacturing experience, over 10 years of exclusive trailer manufacturing it took us another 18 months to design and develop a range of anodised aluminium trailers that have found world acclaim.


We  are now exporting around the globe.


Take a few moments to read on and find out why Spitfire Anodised Aluminium Trailers have been  globally accepted as the industry leader in quality and price.




Price Competitive ..... with galvanised steel trailers;


In house manufacture allows Spitfire to compete with most galvanised steel trailers, certainly in the mid to larger model sizes, but if you compare apples with apples and compare Spitfire's quality accessories, then Spitfire are untouchable in price.


OEM fitting of world class brands provides a first class quality product at a realistic price.


Our standard Models include;





ALKO Torsion Axles.


Not just any torsion axle,  but AL-KO torsion axles. AL-KO are a 63 year old German company who have made and shipped 45 million axles world wide.


Industry standard for trailer suspensions is leaf spring.



Hydraulic Vented Disc Brakes.


Hydraulic vented disc brakes are  standard equipment on Spitfire


We offer two brands, DEEMAXX and Kodiak.


Not just any brand of brake but either Kodiak and Deemax who have established a world wide reputation for quality and reliability in trailer brakes.


Brake lines.


Industry standard for trailer brakes are cable mechanical and usually 'no name' brake calipers, Spitfire trailers use flexible Teflon, stainless steel braided certified lines.





All spitfire lights are approved in  Europe, Australia and the US. In addition Spitfire have 'down lights' .. the lights have a down light which allows you to see the ground if you have to check your load at night and also provides some visual reference through your side mirrors when driving.



Twin Reversing Lights.


We know boating and we know that more often than not you will return after a day on the water and need to back your trailer into your parking spot. 


As such Spitfire Boat Trailers are equipped with twin reversing lights.


Light fittings.


Spitfire wiring looms have a bayonet fitting which ensues maximum water protection. The back of the light has no wires but a socket which the loom plugs into.



Walk Ways.


Walk ways are a very safe and useful accessory, but at Spitfire, on all boat trailers including and larger than our SF 6m - 750 kg trailer, the walk way is standard.


Another saving, as usually  a walk way is charged as an extra.



Aluminium Vs galvanised steel.


It is common knowledge that aluminium trailers traditionally cost 30% to 40% more than steel trailers. Spitfire have broken this myth because we extrude our own metal and make our trailers in-house bypassing metal merchants, middle men and transport.


Spitfire can compete on price on large and mid sized trailers. Small trailers we are close to competing, but the high quality of our accessories is hard to absorbed in a trailer with minimum metal as each trailer has similar standard parts like a coupling, tyres, alloy rims, lights, ALKO torsion axles, alloy wheels  etc.





All Spitfire marine trailers, except our smallest DIY dinghy trailer, come with alloy wheels as standard.





Every Spitfire trailer has certified couplings marked with the approval numbers.



Safety chain.


Inspect a Spitfire trailer and you will find every 5 th link in the safety chain is stamped with the compliance number.





What is ...Factor X 3 or Factor X 5 ?


If you have ever registered a new trailer, you have probably noticed that the registration official has asked for a weighbridge certificate and then checks your brake lights, indicators and tail lights are working, that you have the correct tyres rating and reflectors and then approves the trailer for Rego.


Very rarely will they ask for engineer drawings and check the design strength.


Under the Motor Vehicle Act of 1989 and it's amendments, trailers must comply with stress standards.


For on road use the standard is called Factor X 3. 


That means that a 2,000 kg trailer is engineered to withstand stress loads of 3 times the ATM... or a 2,000 kg trailer will withstand 6,000 kg of stress.


Most Spitfire trailer chassis are engineered to Factor 5 which means a 2,000 kg trailer will withstand 10,000 kg of stress.


This does not mean you can load a 2 ton trailer with 10 ton... what it means that in cornering and braking the trailer will withstand these G force loads.


So before we put a trailer into production, after we have designed the trailer we send the drawings to independent vehicle engineering companies for Certification.


( Note; Not every model is certified. if we obtain certification for say a 7.9 mere trailer at 2 ton and we use the same chassis I-Beam and cross members and make shorter version rated lower, say at 1.85 ton or 1.5 ton then certification automatically covers the shortened lower ATM models.)



Example of Certification;




Hardened aluminium.


Grade 6061 with a hardness ot T6 is the industry standard for most structural, aircraft and marine grade aluminium.


It might surprise you to know that most aluminium trailers are not toughened / hardened.


When aluminium is extruded it is very soft and rated at around T4 in hardness.


This has interesting repercussions for trailer manufacturers.


Most extrusion companies do not want to extrude small orders and consequently most trailer manufacturers buy their aluminium from metal merchants.


Apart from the fact that this increases cost because the metal merchant wants to make his 25% Margin, it also increases cost because the profiles need to be transported from the extrusion factory to the merchant and then to the fabrication factory.


But cost is not the main issue here.


Chassis rails need to be bent.


But you can not bend hardened aluminium because it will crack.


Consequently most aluminium boat trailers are made from unhardened and un-toughened aluminium.


Spitfire however, because of in house manufacturing, follow the correct process.


All Spitfire boat trailer chassis rails,  cross members and aluminium components follow the production procedure below.










Welding if necessary.


Bush finish the surface to remove production marks.






As we know, this is unique to Spitfire Marine Trailers






The Industry Standard for all aluminium trailers is what is called 'Mill Finish'.


'Mill Finish' means that  the aluminium is extruded with no surface treatment.


This aluminium will deteriorate very fast and show signs of staining and corrosion.


All Spitfire marine trailers are Anodised.


Anodise is an electrochemical treatment of the aluminium that provides incredible protection.


It is not a coating that can chip off , it is the actual metal surface that undergoes a change to protect against corrosion and galvanic reaction.


If you are unfamiliar with anodised aluminium, then a simple explanation is as follows.


If you have aluminium windows in your home they are probably powder coated. Powder coating is a paint particle that is dry sprayed and then baked in an oven which melts and forms a very protective pain coating.... but it can chip off.


If you were to go to an airport or government building you would most likely find that the aluminium windows are Anodised.


If you have a metal handle on your refrigerator door, chances are it is anodised aluminium and as you know it gets used frequently for many years with no signs of wear.


In the case of Spitfire marine trailers, not only is the surface anodised, but because we do the anodise after fabrication and hardening, even  inside the tubing, the holes and even the welds are anodised for maximum protection.





These two samples which have been artificially aged in a heated salt bath for the equivalent of 4 years.


The sample on the left is 'Mill Finish' ... the sample on the right is Anodised.


Note the anodised tube is protected from corrosion both outside and on the inside of the tube.



Easy Loader.


Recently there has been a trend by trailer makers to offer boat trailers which they call 'Easy Loaders'.


An easy loader trailer is generally a boat trailer that has the rear cross member formed in a 'U' shape and allows for entry to be guided by the rear rollers.

A good thing... but structurally not so good as the boats are designed to have the maximum weight at the stern. Motor (s), batteries, fuel tanks, the widest part of the hull, etc.


Spitfire trailers believe in maintaining the structural integritry of the trailer and as such we maintain a fixed and full rigid straight rear cross member, which provides exemplary protection to the strength of the I Beam Chassis rails.



I Beam profiles are one of the strongest and lightest designs used in trailer construction.



However they have no torsional resistance and only maintain their strength in the vertical and horizontal plane if they are rigidly fixed.




For this reason Spitfire have designed an 'Easy Loader' that not only provides protection to your boat when loading, it also maintains the structural integrity of the chassis.




We know that sometimes the tide is running out and the wind is blowing a gale when you come back from a day out and it takes a lot to get the boat straight on the trailer.


Spitfire  'Easy Loader' basically means, if you can get the bow of your boat between the tail lights it is almost impossible to hit the metal of your trailer.


All this is possible by having a Spitfire Easy Loader without weakening your trailer chassis with a 'U' shaped rear Crossmember.



Spitfire easy loaders are available as an accessory and will easily fit most brand of trailers.


They are manufactured form stainless steel and available at all Spitfire outlets.






Manufacturing the best trailer is nothing without warranty and service.


Today there are many sole operators making and selling trailers and their warrant is "you return the trailer to the place of purchase'.


This is not much value if you travel or sell your trailer to an interstate buyer.


Spitfire Trailers provide a National Warranty.


You can buy a trailer in Queensland and travel to Perth, Adelaide or Darwin and call on one of our National Distributors for service or warranty.


More importantly, if you should sell your rig to an interstate buyer, the warranty is transferable which must increase your resale value.





The trailer is the oldest vehicle and it has evolved through thousands of years from a war machine, first used as a weapon to run over advancing soldiers.


Today the trailer is a tool that is almost as common as the back yard BBQ.


While the Egyptians were credited with the first trailers, Australia has seen the evolution go from bullock wagons, to sulky to modern day trailers which first were popular in painted steel. 



The painted steel trailers usually lasted around 5 to 10 years before they rusted out. In fact some old bullock wagons have outlasted painted steel trailers.


Around a decade ago, imported  galvanised trailers became popular and some are made from galvanised sheet metal which had no edge protection when cut or drilled and rusted away almost as quickly as painted steel.


Hot dip galvanised trailers offer a longer life, but galvanising is an environmentally unfriendly process which is being banned and restricted in many countries now including China.


There is no doubt that Aluminium is the trailer of the future..... and the future is not so far away.


Anodised aluminium is a gentle product which will outlast the life of most trailer buyers.


Just look at aircraft, there are many Cessna and Piper aircraft that have stood outside in our coastal city airports from the 1960s and 1970s and are still flying today.
