Maintain proper suspension function on your lowered Silverado/Sierra with the MaxTrac 400500 Rear Shock Extenders. Specifically engineered for 1988–1998 Silverado/Sierra 1500 2WD trucks, this bolt-on pair of extenders corrects the shock angle after a rear drop—ensuring smoother performance and improved ride quality.

Perfect for builders who've lowered their C1500 but want to reuse factory-length shocks, these extenders reduce the need for aftermarket shocks while preserving full suspension travel. Whether you're running a flip kit or drop shackles, MaxTrac shock extenders help prevent shock binding and bottoming out, giving your static drop setup the comfort and control it deserves.

Crafted from heavy-duty steel and finished for durability, the 400500 extenders are the no-fuss solution to maintaining suspension integrity on your dropped Silverado/Sierra.
