4130 4 Link 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.

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
