GMC

MaxTrac Suspension's rear shock extenders are designed to provide extreme stability for your lowered GMC truck or SUV. When brand new shocks aren't required or needed, these extenders lower the mount of the current setup, adjusting the angle of the shock to its correct angle, which makes the shocks more efficient. MaxTrac’s shock extenders are fabricated from laser cut steel and powder coated to offer you the quality and durability that you are looking for. Plus, the shock extenders bolt right into your existing shock mounts for an easy no-drill installation.

For the 99-06 Sierra trucks, when lowering the rear of the vehicle 4-6", it’s a great idea to use a shock extender on the passenger side shock, as lowering the vehicle puts the shock in a slightly horizontal angle, compromising the shocks ability to properly dampen the ride. This extender fixes that issue! The driver side shock maintains an ok vertical orientation when lowered to these heights, so a shock extender isn't needed.
