New Rear Leaf Spring for the 2005-2016 Hilux pickup KUN25 & KUN26 Double Cab or Single Cab, now manufactured in the UK by leading manufacturer Owens

**Please ensure you are ordering for the correct Hilux 4x4 models listed, it is the customers responsibility to return these heavy items if ordered incorrectly** 

This new rear spring comes complete with rubber bushes at either end of the spring eyelets as pictured. It has been designed to the original specifications of the strongest spring that was fitted to the Mk6 2005 - 2016 Hilux, that means a spring that has been made to ride the same but carry the max. permissible loading.

What Owens offer in their manufacturing:
A spring or spring pack is made up of individual "leaves", in this case, it has five and known as a 3+2 leaf spring. The top 3 leaves make up the vehicles ride and smooth suspension, then when loaded the spring compresses onto the two lower Load leaves making one complete load bearing suspension spring.
About this spring:

  • Highest grade BS970 spring steel shaped by their hot camber forming process between 950 and 1050°C.
  • Quenched in oil and drained they pass through the tempering furnace between 500-550°C to achieve the correct Brinell hardness reading.
  • The top leaf or "Main-Leaf" is 9mm thick and rolled at either end to retain the bushes and attach to the chassis. 2nd and 3rd leaves are 8mm thick, together they provide the ride, then this spring has two very thick 14mm "Load Leaves", the thickest that was designed for this model.
  • The pack has a central bolt which not only holds the leaves together but also locates and supports the axle central to the spring for correct axle alignment.
  • Shot peening - Carefully controlled shot peening process significantly increases the fatigue life of a spring. 
  • In between at the ends of each "ride leaf" are wear pads, these prevent the spring from wearing away against each other when compressing and extending during everyday road use, again showing quality in construction, attention to detail and above all prolonging the life o the spring.
  • Bushes are in the form of the original designed rubber "metalastic" front eyelet fixed bush and two "top hat" rubber bushes to make up the rear spring eyelet bush.Quality of steel and construction, number of leaves, and thickness of these individuals leaves is what truly sets this spring apart from others.
  • The springs are painted in a "Transport" paint, as with all suspension components supplied, paint is not covered under warranty due to the very nature and position of the component.

At RoughTrax we pride ourselves on supplying what we feel to be the best-valued product for the money and quality, this is where this spring excels, whats more it's a UK manufactured product which we are proud of.

High-end leaf springs help to prevent body roll in bends and also perform under load when towing or carrying heavy loads whilst improving vehicle looks and handling, for off and on road use.

Many cheaper Imported springs will increase the thickness of the top ride springs to compensate for using cheaper poor quality steel, this, in turn, results in a very harsh ride and individual leaves become susceptible to cracking.

Good practice:

  • It is recommended that you replace the Front Spring Pin SUHW007 with this spring as they have a habit of seizing in the front bush of the old spring,
  • It is always good practice to replace all springs as a pair so as to even out the loading, if you have one new spring acting with one old then the new spring will be under greater pressure, it could also affect the ride heights between old and new.
  • Replacing "U" bolts too is a good idea, they can be a real pain to undo!

About Owens:
The company is totally committed to quality and this is evident by its accreditation for the manufacture, repair, and supply of all spring types by to BS EN ISO certification, which has been held since 1991, what's more, they also hold the ISO9001 certification.

Flying Scotsman:
Manufacturing springs for well over 30 years their experience is second to none, in fact one of their highlights was being the chosen manufacturer to replace one of the broken leaf springs prior to the Flying Scotsman’s inaugural trip and are currently repairing and replacing the spare springs while the famous engine carries out its tour of the country

Fitting Tip:
Tighten all spring retaining bolts and shackles when the vehicle is at normal ride height, this is done once the vehicle is assembly, lowered back to the ground with the weight back on the suspension and bounced a few times, this allows the bushes to settle in and vital for correct final assembly.

Product Reviews for Owens Rear Leaf Spring UK Manufactured

Questions & Answers for Owens Rear Leaf Spring UK Manufactured


Should you replace rear springs as a pair?
It is always good practice to replace as a pair, because if you only fit one new spring then this will stronger than the weaker one still fitted and this will result in the vehicle sitting higher on the side the new spring is fitted too. Also, the new spring will be taking more of the load which will not be spread evenly across the two springs.

Do the rear chassis bushes come with the spring?
No, only rubber bushes to fit either spring eyelet end are supplied. We do sell a Urethane upgrade bush kit by Whiteline if needed.

Is it necessary to replace all the pins / shackles?
No, if you know your originals are in good working order and not corroded on the pins then you can re-use, however, the front pin bolt holding the spring to the chassis has a habit of seizing in the front bush so I would recommend replacing this at the very least. Our rear shackles are now greaseable so many customers are replacing them out of choice.

What about "U" bolts?
Personally, I would always replace these by cutting off the old ones. The time it can take, let alone the effort! to try to remove an old U-bolt can outweigh the price of a pair of new ones.....your mechanic will certainly prefer this option !!
"U" bolt Torque - 90 ft/lb or 123 nm, always torque evenly and of equal length.
It's widely known in the trade that cracked springs in the "U" bolt area is down to insufficient torque so always ensure this is done correctly and re-checked after some usage.
Cracking of a spring in the "U" bolt area is not covered by warranty, it's widely publicised throughout spring manufacturers that this is proven to be incorrect "U" bolts torque.

Does the spring material really make a difference?
Without question, yes, as cheap spring steel manufacturer will more than likely have increased the thickness of the individual leaves to compensate for poor materials. The idea being to try to stop it either cracking or fading early when continually in use, this in turn results in a hard riding spring and indeed one that does end up cracking after prolonged use as they not so supple in the ride leaves.
