Losi LOSB2871 Nutted Shock Shaft Piston Kit

This nutted shock shaft and piston kit is a genuine Losi front suspension component built for the 5IVE-T and MINI WRC platforms. The kit includes a shock shaft paired with a lock nut that securely holds the piston in place, preventing it from loosening or shifting during hard use, along with a delrin piston machined to a tighter tolerance than stock. That tighter fit against the shock body reduces internal blow-by, resulting in smoother, more consistent damping and a longer-wearing part overall compared to looser-fitting alternatives. As a direct factory replacement, it restores proper front shock function on trucks with worn, bent, or damaged shafts and pistons without requiring a full shock rebuild kit. Reliable, smooth-acting shocks are essential for maintaining control and traction on the rough terrain these large-scale trucks are built to handle. This kit is a practical upgrade and maintenance part for 5IVE-T and MINI WRC owners looking to keep their front suspension performing consistently over time, whether refreshing worn shocks or building up spares.
