Our 6” Performance System has been designed utilizing our industry leading crossmember and spindle technology.
The front high arched 1/4" thick steel crossmember has been formed to fit to the bottom of the frame without having to cut or modify it for a fast installation. Extensive design work was given to the extended length steering knuckles specifically for the Aluminum component version keeping track width near stock and working properly with the Stablitrac® safety functions.
The front differential is relocated with heavy duty brackets while a tightly formed 1/4 ” thick steel skid plate provides protection for offroad use. The rear suspension is upgraded with add a leafs and 5” tall blocks and u bolts.
