Un-equal Length No-Prep/Radial 4 Link Kit

Un-equal Length No-Prep/Radial 4 Link Kit.

This 4 link kit is designed with a shorter upper arm to create the upper and lower arms to be un-equal. This set up acts like a stock suspension car which allows for quick separation to plant the tyre into the track. The kit is much stronger and has a lot more adjustability over stock mounts. This configuration is versatile and works great on radials as well as slick tyre no-prep. Chassis brackets can be cut down to suit stock floor.

Brackets are 6mm mild steel with 3mm doublers, 1/2" link holes with 10mm adjustment increments, 1 5/8" bracket mounting through holes, NAS or Grade 8 bolts, 3" or 3.5" diff tubes. Chromoly Brackets available upon request, please contact for pricing.

Control arm length is recommended to be- Uppers, 300mm-500mm. Lowers, 450mm-650mm

With no-prep racing booming in the states and gaining popularity in Australia, we wanted to offer locally available parts to help you get your car to the track.
