This stage 9 kit also includes four 2.5 Pro-Series CST shocks & front shock mounts engineered specifically for the 2.5 CST reservoir shocks. The CST Pro-Series shocks offer adjustable ride-control, allowing the driver to self-tune the shocks & ride to their own preference.

Steering stabilizer brackets are built into the kit and our stabilizer shock kit can be purchased as an optional upgrade. For the rear this 4-6″ kit includes BILLET 1″ lift blocks and heavy duty, zinc-plated u-bolts.

No cutting of the front differential required.

Retaining the factory front wheel track width allows this kit to work perfectly with all of the trucks stability assist features including the GM StabiliTrak system.
