Losi LOSA5413 15mm Shock Shaft 4x57mm TiNi

This 15mm shock shaft measures 4mm in diameter and 57mm in length, built with a titanium nitride coating for the Losi 8IGHT-B and 8IGHT-T platforms. The TiNi coating adds a hard, low-friction surface that reduces seal wear and drag as the shaft cycles through the shock body, helping the damper move smoothly and consistently even after repeated hard impacts and long sessions of off-road racing. A precision-ground shaft also keeps the piston tracking true inside the shock body, which matters for even damping and predictable handling through rough terrain and big landings. This shaft is manufactured to factory dimensions, making it a direct replacement for a bent, pitted, or worn stock shaft rather than a redesigned part. Because shock shafts take direct hits during hard landings and rock crawling, keeping a quality replacement on hand helps drivers get a damaged shock back into service quickly instead of rebuilding the entire shock assembly. One shaft is included. Built for the Losi 8IGHT-B and 8IGHT-T platforms, it restores smooth shock action and helps maintain consistent suspension performance.
