ICON Multi-Rate RXT Rear Leaf Pack with Add-In Leaf for 2014-2016 Toyota Tundra, Part 158509

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. This ICON user-adjustable multi-rate leaf pack features tip inserts and leaf separators to reduce friction and increase ride comfort, while a military wrapped front eyelet improves durability and strength. TECH NOTE: For best results (and increased wheel travel), use in conjunction with ICON RXT rear shocks.

• “ICON 1K” tested under rigorous off-road conditions to validate tune, performance, strength, and durability
• Potential for increased wheel travel when used with RXT shock (up to 25%) without sacrificing up-travel
• Includes additional leaf with 15% or 25% increase in spring rate for more laden "outfitted" vehicles
• Galvanized leaf separators reduce friction and aid in corrosion resistance
• 3 user-adjustable spring rates for unique vehicle configurations
• Direct bolt-in to OEM spring location makes for an easy install
• Leaf tip inserts reduce noise and increase ride comfort
• Military wrap front eyelet for increased durability

Upgrade the rear suspension of your 2014-2016 Toyota Tundra with the ICON Part 158509 Multi-Rate RXT Leaf Pack. Designed to work with the additional travel offered by the ICON RXT Rear Suspension System, this replacement leaf pack provides improved ride quality, increased droop travel, and user-adjustable spring rates for a wide range of truck configurations. The direct bolt-in design installs in the original spring location for a straightforward upgrade.
The ICON multi-rate leaf pack includes an additional leaf that can be exchanged or added to increase spring rate by 15% or 25%. This adjustability helps support Tundras carrying added equipment such as a bed rack, rooftop tent, spare tires, recovery gear, or other accessories. The base spring rate is slightly lowered to enhance ride comfort and suspension articulation, while the additional leaf helps accommodate more heavily outfitted vehicles without compromising overall performance.
Tip inserts and galvanized leaf separators reduce friction, noise, and wear while supporting a smoother ride. A military-wrapped front eyelet improves leaf spring strength and durability for demanding off-road use. ICON 1K testing validates the design under rigorous conditions for tune, performance, strength, and long-term durability. When paired with ICON RXT rear shocks, the system has the potential to increase wheel travel by up to 25% without sacrificing up-travel.
Designed for Toyota Tundra applications, the ICON Part 158509 leaf pack delivers a durable, configurable rear suspension solution for daily driving, overland builds, and off-road vehicles with varying load requirements. Professional installation is recommended, and the system should be used with compatible ICON RXT rear shocks for best results.
