ReadyLIFT 8″ Lift Kit With Bilstein Shocks Rear Shocks – Available For 2007-2020 Toyota Tundra Trucks! You want a quality BIG lift kit for your Tundra® ReadyLIFT delivers a great lift kit that will increase your ground clearance two inches more than the competition!

This is a complete kit that includes two (2) rear Bilstein Shocks which are the number one used shock on Tundra trucks!

Note: Factory Wheels – This system will only work with factory 20′ wheels – will not work with factory 18″ wheels. Aftermarket wheels okay.

Note: Will not work with the TRD rear sway bar option.

The 44-5877 8″ lift kit for Tundra trucks kit is packed full of great features! Starting with our ultra strong laser cut, CNC bent, welded and boxed sub frame drop assemblies that not only keep your suspension geometry where it is supposed to be but also increases your ground clearance over 2″ over the competition! Our unique and precision designed iron knuckles feature CNC machining to guarantee precise fit while allowing for retention of the factory tie rods (minor trimming required).

We also sought to correct so many of the issues that exist with other Tundra lift kits on the market. The 8″ of lift is created by our innovative and industry-leading offset spacer design. These strong steel spacers attach to the factory strut – resulting in a factory ride – while positioning the suspension in such a way as to not increase track width. What does that mean? It means your front tires won’t still out further than your rear tires like with other kits. AND, it means you can run your stock 20″ wheels and use your spare tire if needed. Our sub assembly design features a truly innovative approach to dropping the differential. Our diff drop kit is engineered for easy installation – easiest on the market – and correctly positions the differential to maintain great CV axle and driveline angles. With our 44-5877 8″ lift kit you can rest assured you will not be wearing out those new tires. Our system is built around maintaining correct alignment and geometry specifications. For the rear, this kit includes our time-tested OEM-style cast iron rear lift blocks and longer u-bolts with hardware. Additionally, we also include bump stop extensions all the way around as well as sway bar frame mount brackets to keep the front sway bar in a factory position. All of this contributes to an excellent driving and handling suspension system that truly complements your Tundra truck!

How big of a tire can you run? We recommend 37″ as the maximum on a 9″ wheel with a +25 offset for the least chance of rubbing. (Front mud flaps may need to be removed.)

  • 37″ Maximum tire diameter

Coilovers Description:

46-5780 – Bilstein Reservoir Coil Over Shock Upgrade Kit – 2007-2020 Toyota Tundra 2WD/4WD – with ReadyLIFT 6″ or 8″ Lift Kits (excludes TRD Pro).

It’s been worth the wait. Engineering a true performance front coil over shock and spring to work cohesively with our Tundra lift kits takes time. But the wait has been totally worth it once you get a chance to test drive a ReadyLIFT-equipped Tundra with our proprietary 46-5780 upgrade kit.

Some of the exciting features of this new program are based off Bilstein’s 2.625″ monotube design reservoir coil-overs designed for the most extreme terrain. Each shock features custom valving from over a year of testing by ReadyLIFT and Bilstein engineers. Lower rod ends feature 3/4″ bearings and proprietary high misalignment spacers while ReadyLIFT-specific 90-degree reservoir fittings ensure ideal canister placement and hose fitment. ReadyLIFT and Bilstein included Eibach in this project, tasking the spring giant with developing a specific ERO coil spring just for this application. These springs are unique in the marketplace, featuring a silver powder coat finish with the ReadyLIFT brand name included on the spring.

Yes, these shocks are that cool! But how did we get it work with our 6″ and 8″ lift kits? The answer is in the heavy-duty plate steel upper shock mount our engineers designed for the perfect mating of a thoroughbred performance coil over with the most popular Tundra lift kit on the market. These new top mounting brackets are the key to making this exclusive program work.

When you combine the best lift kits and the best performance reservoir coil over shocks matched with the best coil over springs, the results are amazing. You just cannot get a better made-in-the-USA performance coil-over that provides unmatched ride quality with the ability to rebuild, if ever required. And they look amazing once installed on these trucks!
