Product Description

The ICON 51100 Progressive Add-A-Leaf Kit provides 1.5 inches of rear lift while simultaneously improving ride quality on your Toyota Tacoma or first-generation Tundra. This kit replaces the harsh factory overload leaf with a 3-leaf progressive rate pack that effectively lowers the rear spring rate by approximately 10%, delivering a more compliant and comfortable ride both on and off-road. The progressive design means the spring rate increases as the suspension compresses, maintaining load-carrying capability while eliminating the stiff, jarring ride associated with factory overload springs. Installation is straightforward using common hand tools - simply remove the factory overload spring and install the ICON pack using the included extended U-bolts and center pins.
