LEAF SPRING

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. While many Tundra owners will embrace this, there are those who have outfitted their trucks with a significant amount of weight in the form of a bed rack, roof top tent, spare tires and parts or other additions. 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.

Reference Information

Leaf Spring, Multi-Rate RXT, Includes Add-In Leaf, Toyota, Tundra, Each

Icon Vehicle Dynamics multi-rate leaf spring packs include an add-in-leaf to create systems that offer a major performance gain for most any truck setup, even those requiring more load-carrying capabilities. These user-adjustable multi-rate leaf packs feature tip inserts and leaf separators that lessen friction, reduce noise, and increase ride comfort, while military-wrapped eyelets improve the durability and strength of the leaf spring. To increase the ride quality of your truck and gain additional droop travel, the spring rate has been lowered slightly—and this is where the add-in-leaf works. For those who have outfitted their trucks with significant weighty additions, the additional leaf can be exchanged or added to the pack yielding an additional 10 percent or 40 percent spring rate (depending on kit). OE leaf springs can have limiting factors … especially with fully loaded rigs with racks, rooftop tents, and the like. Redefine the potential of your truck; adjust leaf spring rate to compensate for your specific truck setup, be it unloaded or fully loaded, with Icon multi-rate packs.
