Deaver 2007 - 2021 Toyota Tundra 2" Lift Full Replacement Leaf Pack # K37

Deaver 2007 - 2021 Toyota Tundra 11-Leaf Spring Pack # K-37. Provides approximately 2" of lift on stock weight Tundra trucks. Deaver developed their K37 Leaf Spring Packs to help reduce the harsh ride that almost all of the Tundra trucks exhibit on poor or rough road surfaces. The factory overload in the stock leaf packs causes a spike in the spring rate when the rear suspension is compressed (like when it hits a large bump) that makes the back of the truck feel harsh when driven on rough roads or off-road. The 11-leaf design allows for the initial spring compression to be quite soft and then it gets firmer and firmer as the spring is compressed more.

Lift Height Information:
The approximate lift height increase is between 3/4" and 1" over stock height on trucks in GOOD to EXCELLENT condition when the Total Chaos shackle is also installed. Please note that it is quite common for the factory Toyota leaf packs to flatten out. If your existing Tundra leaf springs are flat (or have negative arch) the lift height your truck achieves may be greater. That's only because your existing Toyota spring packs are failing and can no longer hold the rear of the truck up properly.

Important - Please Read!
This leaf pack is NOT designed for use on Crew Max Trucks. Deaver recommends use of the U-748 on Crew Max models. These Deaver Leaf Spring packs are designed for use with aftermarket shackles. Deaver recommends the use of Total Chaos Fabrication Shackle part number 49704. These shackles can be purchased via our website separately. Aftermarket shackles are NOT included and will be required before the K-37 can be installed on your Tundra.

Towing / Hauling Information:
The K-37 leaf packs are NOT designed to increase towing or hauling capacity. Deaver recommends the use of their U-748 spring packs if you regularly tow or haul heavy loads with your Tundra. The Deaver U-748 (not this item) are designed for trucks that are equipped with additional accessories, carrying camping / overlanding gear or equipment.

This item does NOT qualify for free ground shipping.
