Requires: ICON Vehicle Dynamics U-bolt kit 52050 (sold separately).

The ICON Vehicle Dynamics multi-rate RXT leaf pack with add-in leaf is a replacement leaf spring pack for the 2007-2021 Tundra. Tip inserts and leaf separators cut friction for a smoother ride, and the included add-in leaf can be added or exchanged for 15% or 25% more spring rate on a heavily outfitted truck.

To take advantage of the additional travel that the RXT Rear Suspension System offers, ICON engineers had to scrap the OE leaf springs and develop a replacement that addressed issues found in the R&D process. The result is a user-adjustable multi-rate leaf pack that offers a major performance gain for almost every Tundra setup imaginable. Features like tip inserts and leaf separators reduce friction and increase ride comfort, while a military wrapped front eyelet improves the durability and strength of the leaf spring. To increase the ride quality of the truck and gain additional droop travel, the spring rate has been lowered slightly. Understanding this, the leaf pack was designed with an additional leaf (included with kit) that can be exchanged or added to the pack yielding an additional 15% or 25% in spring rate that will handle more "outfitted" vehicles.
