Kelderman Manufacturing has introduced a front and rear four-link coil over kit for late model Ford 4x4 Super Duty pickups — the Kelderman Koilover Kit. Kits are now available in either 8” or 12” for 2005 and newer F-250 and F-350 Ford Super Duty trucks. The front kit replaces the factory coil springs and shocks with an engineered four-link design. The heavy-duty four link rear kit replaces the leaf spring using King coil over shocks.
