Drivetrain and year checks
On GM trucks, a rear shock’s fit depends on the drivetrain, cab and suspension package as well as the model year. Two-wheel drive and four-wheel drive trucks often use different rear mounting points, so confirm the drivetrain before matching a shock. Leveling kits and lifted setups can also change the length a shock needs.
Rear shocks are usually replaced in pairs on each axle, so both should come from the same part family. Inspect the mounts and bushings while the old shock is off. Worn bushings cause clunks and uneven damping even when the new shock is correct.
- Compare the old shock’s eye-to-eye length
- Check mounting bolts for stretch or rust
- Replace worn bushings along with the shock
- Tighten fasteners to the vehicle’s specification

Vehicle fitment
It fits four rear applications: the 2007-2011 Chevrolet Silverado 1500 2WD and 4WD, the 1999-2006 Chevrolet Silverado 1500 2WD, the 2007-2011 GMC Sierra 1500 2WD and 4WD, and the 1999-2006 GMC Sierra 2WD. Front positions are not among its applications.
The 1999-2006 Silverado and Sierra entries are 2WD rear only, so 4WD versions of those years are not in the list.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Because this is an OEM direct replacement rear shock, the original mounting points are the reference; check that your year, drivetrain and mounts match the listed application before fitting.
What’s included
Sold as each, so one shock per unit. Check the package contents for mounting hardware or bushings before installation.
