(888) 312-8812 Login SignupSecuring a heavy-duty axle to the suspension becomes a more dependable process with the Hendrickson Air Suspension Axle U-Bolt Kit and its semi-round bend U-bolts. The radius bend matches the contour of the axle tube, allowing clamping force to follow the tube surface rather than concentrating at flat contact points. This Hendrickson S-21140 kit includes four 8-inch U-bolts with matching nuts and washers, replacing earlier S-2003 hardware used on HKBOX and C-52 suspensions. A 0.87-inch rod diameter provides the tensile strength required to maintain axle position under loaded conditions. That secure clamping support helps keep the axle aligned within the suspension during operation.
