ReadyLift® leveling kits are the fastest, safest, least expensive way to bring the front of your vehicle level with the rear. Our innovative Smart Strut Technology mounts on top of the strut assembly, eliminating the hassle, time and danger of compressing springs. ReadyLift® steel strut extension will maintain a smooth OEM ride without adding pressure to stock suspension components, guaranteed!
The 66-5000 strut extension provides 3” of lift which gives clearance to add up to 33” wheels and tires to the
1999-2006 Toyota Tundra 2wd & 4wd. For information about tire and wheel sizes please visit the ReadyLift
Tire Sizing and Calculator Page.
Installation is simple and requires no strut preloading, cutting, or modification of factory installed parts. While other kits cost thousands to buy and hours to install, ReadyLift® can be installed one to two hours and costs less than the price of a single custom wheel.
ReadyLift Lifetime Warranty Included! All ReadyLift® products are backed by a lifetime warranty for as long as you own your vehicle and includes all necessary parts, hardware, detailed installation instructions, and two color decals.
Note: It is ReadyLift’s position that our objective is to provide a product that levels the vehicle. Through on-going research we have discovered that Toyota trucks have a unique pattern of being manufactured and sold with varying degrees of rear to front rake. It appears that many Toyota trucks are not the same height or possess the same rake as the same stock truck sitting next to it. Our research has determined there can be as much as 1.0” difference in rake and ride height from truck to truck. TRD-equipped trucks often have only 1.0” of rake compared to a non-TRD truck. Measurements on some customer’s trucks have revealed as much as 1.0” difference in the factory front end height.
If you measure the truck at stock height, then install a 3” strut extension and determine after installation and alignment that the truck sits nose high, you most likely are an owner of one of the trucks that has less rear to front rake. To compensate for the difference, ReadyLift suggests installing one of our 1.0” (66-5001) Rear Block Kits to achieve a slight rake to a level stance.
