KYB SM5956 Shock Mount Kit with Bumper and Bellows

The KYB SM5956 is a complete shock mount kit that includes a shock mount, jounce bumper, and protective bellows boot — everything needed to properly restore upper shock absorber mounting hardware in a single package.

Shock Mount: KYB shock mounts eliminate the vibration and noise caused by old, hardened vibration insulators, cushioning road impacts to reduce the jarring effect, noise, and harshness transmitted into the vehicle cabin. Engineered to OE quality standards, this mount is designed to optimize suspension performance for each specific application.

Jounce Bumper (Bump Stop): The included jounce bumper acts as a travel-limiting buffer that prevents the shock absorber from bottoming out under severe compression, protecting the shock and surrounding suspension components from damage and extending overall service life.

Bellows Boot: The protective bellows dust boot shields the shock absorber piston rod from road debris — including rocks, dirt, dust, and stones — that cause abrasive wear to the polished shaft, upper seal, and bushing. Keeping contaminants out helps prevent premature shock failure and extends strut life.
