Tuff Country 03-23 Dodge Ram 3500 4wd (w/4in Rear axle) 4in Rear Block & U-Bolt Kit

The Tuff Country 97051 is a 4" Rear Block & U-Bolt Kit designed to raise the rear of Dodge Ram 2500 (2003-2013) and 3500 (2003-2025) 4WD trucks with a 4" rear axle tube. This kit increases rear clearance and stance without compromising overall handling. The heavy-duty cast iron lift blocks are tapered to minimize driveline vibration, providing a smooth ride. The kit includes zinc-plated extended rear u-bolts (9/16" x 4 1/8" x 17" Round) for secure mounting and corrosion resistance. Installation is a simple bolt-on process, placing the lift blocks between the factory rear leaf springs and the axle. Extended-length shocks are typically required for blocks 2" tall and taller.
