Owen Springs, UK Manufactured Rear Leaf spring suspension kit for the 2005-2016 KUN25 & KUN26 Hilux 4x4 Pickup Double Cab or Single Cab models.

**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**

  • Kit comes complete with all hardware listed to bolt the leaf springs onto the vehicle.
  • The springs have been designed to the original specifications of the later strongest spring that was fitted to the Mk6/7 2005-2016 Hilux 4x4 pickup.
  • Springs have been made to ride the same but carry the max. permissible loading set for the vehicle.
  • Hardware contains all greaseable pin and shackles extending life of the components along with Poly bushes from Australia.

The Owens UK Manufactured springs:

Consist of 3+2, 5 leaves to form the spring pack mounted with front a metalastic bush at the front. The first leaf is 9mm, and the next two 8mm Leaves make up the ride springs under normal road use, then when loaded compress onto the 2x 14mm thick load springs enabling these springs to carry a constant load. In early models these lower springs were thinner, Toyota then increased the thickness to 14mm which is what makes these Owens springs equivalent to those later springs.
You will also notice that Owens springs, as does Toyota, manufacture their springs with intermediate spring end wear pads between each leaf, this prevents the individual leaves from wearing against each other over prolonged use, something that cheaper springs simply don't do.

To mount the springs we supply a pair or greaseable Karsons rear shackles, greaseable eyelet bolts, four Karsons "U" bolts and a set of performance bushes for the rear shackles, you now have yourself what we believe to be the best quality spring steel springs and mounting components on the market.

So this kit is based entirely on quality branded components that last and used World Wide. 

Kit Contains:

  • 2x Heavy Duty 5 leaf rear leaf springs with wear pads between each leaf, manufactured by Owens in the UK and mounted with a front Metalastic bush.
  • 1x Pedders 8 piece performance Red Polyurethane rear shackle bush kit.
  • 2x Karsons rear greaseable spring shackles,
  • 2x Karsons spring pin greaseable retaining bolts (fit at front of spring to chassis).
  • 4x Karsons "U" bolts (x2 pairs) Torque 90ft/lb - 123nm

Whilst improving the vehicle's looks and handling, RoughTrax suspension kits help to prevent body roll in bends. Ideal for towing, off road & on road. Manufactured in the UK. Nothing else is required to fit, simply bolt on & enjoy!

  • 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.

The most comprehensive leaf spring kit on the market!

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.

Rear Ride Heights:
The average measurements below, given by customers after fitting, are always taken from the base of the wheel rim vertically up to the wheel arch:
(This way the tyre condition or pressure does not affect the measurements)

These measurements should help provide you with an approx. idea of where the vehicle will sit but are only as a general guidance and can vary vehicle to vehicle:
798mm with 16" wheel Rims
810mm with 17" wheel Rims

Product Reviews for Owens Rear Leaf Springs Kit - KUN25 & KUN26

Questions & Answers for Owens Rear Leaf Springs Kit - KUN25 & KUN26

What about "U" bolts?
"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, because a 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.
