Our Triangulated 4 Link kit is a proven set up for both on-road and off-road. The kit has raced and finished some of the hardest of races. In the On-Road form it has been engineered in every state/territory Australia wide. And like always we do our best to keep as much of our products as home grown as possible, this product is proudly manufactured here in Australia.
This kit leave no guess work. It all self aligns it self to get the perfect location everytime. Simply clean up the area that needs to be welded set it in place and weld the mounts on, Drill one hole, make a couple more welds and your done.
The biggest advantage of a triangulated 4 Link over the traditional 5 link is removing the rear pan hard rod which helps get rid of the some of the poor handling from your patrol. It improved rear suspension geometry offering better roll axis and anti squat than that of the factory 5 link. By removing the pan hard to improve the axle centring under the vehicle in rough terrain Transmits power to the ground more effectively. This kit in short decreases rear steer and increases suspension articulation while giving more predictable handling.
We use our own heavy walled bush sleeves with only factory Nissan rubber bushes in the bushed options. All steel links are extra thick walled and lower links for added strength have a spine welded its entire length. All Heims joints are DFI brand so you know they are quality and offers the maximum amount of flex and articulation.
Please be aware this kit requires welding and should only be installed by a competent fabricator, boilermaker or someone that is experienced in this kind of works. Designfab Industries will assist with all forms of communication and required information that is to be provided to your chosen engineer. Designfab Industries DOES NOT imply or suggest that any of these kits be installed then driven on road without a sign off by a qualified engineer in your state.

Additional suggestions are to relocate your shock mounts or do a coilover conversion at the same time to unlock this kits full potential. The addition of rear spring brace is recommended as this kit will lead to more flex putting more pressure on chassis mounts leading to the common breakages.
To answer the common questions. Yes you have to remove the Sub tank. Yes you have to replace or modify the chassis cross brace infront of the diff.
