Billet 1/8" Adjustable Chassis 4 Link Bracket Kit

We have had numerous requests to offer a complete 4 link kit rather than individual items. This kit features several options to customize to your particular requirements.

It is becoming quite popular and common to multi-class race or go no prep racing with the same car.  Having to swap back and forth between a small or big tires for these events can be challenging when a cars suspension geometry wasn't designed for the swap. This chassis bracket when combined with our housing bracket will accommodate either small or big tire combo geometry offering a favorable IC/AS adjustment range for most applications.

Our top of the line solution for 1/8" adjustment tuning on the traditional chassis 4 link bracket now available in a 15" height! The bracket assembly is made of billet hardened 4140 utilizing a keyway system making it a great choice for longevity and durability in extreme conditions. Heim bracket adjustment range is suitable for both small and big tire applications.

The 1/4 bolt serves as the adjustment indicator for a given heim hole choice, adjusting through the sweep in 1/8" increments up to 5/8" before needing to adjust to the next heim hole.  Because the upper adjustments are on an angle, the upper 4 link bar stays at the same approximate nominal length through the adjustment sweep making the adjustment variable more consistent. 

This kit uses our billet adjustable shock mounts offering a lot of adjustability vs a fixed coilover mount. This feature is great for those that don't have their chassis geometry laid out but know with this kit they will have the range of adjustment required once the layout has been determined
