King shocks’ bump stop mounting sleeves are made from .093 wall Chromoly tubing. The sleeves are machined for clearance from the top (eventually closed) end before the laser cut tops are tig welded on leaving the first 1.25” at the open end at a smaller size to provide a snug fit on the bump stop body. The locating pin registers into the top plate then the bump stop’s threaded boss is bolted securely to the mount. King’s mounting sleeve design holds the bump stop around the entire outside diameter without crushing it like pinch bolt designs. The sleeves are delivered raw so they can be welded directly onto your chassis.
