PEAK DSSV Coilover Summit Kit with Rear Blocks




The Peak Suspension Summit Combo Kit gives you the complete package. We have included the Peak Suspension Coilover Conversion, Peak Suspension Upper Control arms and Peak Suspension 1″ Rear Lift Blocks. Not only do you get adjustable lift from the Peak Coilover Conversion kit but also receive additional droop and more stability from the control arms. Plan to make your way to the Summit? We have you covered.

Whether you’re looking to bring the front of your truck up to eliminate the stock rake, improve the OEM ride and capability, or compensate for weighted front modifications, Peak Suspension has designed this coil-over conversion kit for your Chevy Colorado ZR2.

Through extensive on and off-road testing we have been able to modify the ride height of the front of your ZR2 without compromising the awesome capability of the OEM DSSV Multimatic shocks!

This kit allows you to select a custom rate and then adjust the threaded collar to your desired ride height from 0″ – 2.25″ of lift as well as a rear block to add 1″ of rear lift.
