SuperSprings work alongside your truck's factory leaf springs to add extra load-leveling support exactly when you need it — the self-adjusting design engages more under heavier loads and backs off when the bed is empty, so ride quality stays comfortable either way.
Sold as a left/right pair, the SSA22 is built from SAE 5160H high-grade steel that's shot-peened to relieve stress and extend service life, and a typical install takes about an hour.
Made in the USA and designed for a roughly one-hour install, it's a solid way to firm up a rear end that's sagging under a heavy trailer tongue or camper load.
