King Air Bump Stops allow you to use all of your vehicle's effective suspension travel by preventing excessive impact to your chassis and drivetrain. King bump stops are available in in 2.0 and 2.5 body sizes and bump travel from 2 to 4 inches. They are designed to work well on all types of suspension systems including A-arms, trailing arms, and solid axles. Bump stop sleeves are used for mounting the bump stops and are designed to hold the bump stops using their large top cap bolts instead of squeezing the body like most other brands.

Servicing, Tuning, and Rebuilding
All King shocks are built to take a lot of abuse, but no matter how well a shock is built, parts will wear out and need to be replaced. For this reason, King designed their shocks to be serviced quickly and easily with just a few simple hand tools. Filthy Motorsports can get you all the King replacement parts and valve shims you need to do the job yourself, or you can bring (or ship) the shocks to us and we'll get them serviced for you.

Note 1: Product ships uncharged.
Note 2: This product may require custom mounting that should be performed by a professional.
Note 3: Do NOT weld within the last 1 inch of the bump stop can opening as this will warp them.
Note 4: Bump stops will fit old style cans if stem hole is enlarged to 1.0" for 2.0, 1.20" for 2.5"
