Specs At A Glance

Good To Know

Q: Do these struts come as a matched pair? A: Yes, this listing includes two rear shock strut assemblies so both sides of the axle can be serviced together. Replacing them as a pair helps keep damping even from side to side.

Q: Will these fit a standard Sierra 1500 that is not a Denali? A: Fitment is listed for the GMC Sierra 1500 Denali from 2015 to 2018. Verify your model, trim, and suspension package against the listing before ordering, since non-Denali trucks may use different rear struts.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
