4 Inch Lift Kit 2015-2021 Toyota Tundra TRD pro ReadyLIFTThe ReadyLIFT Pro Plus 4 lift kit is specifically designed for 2015 2021 Toyota Tundra TRD Pro trucks, offering a 4 Inch front lift while retaining the original 2 Inch factory lift, equating to a total height similar to a 6 Inch lift on standard Tundras. This kit allows continued use of factory Bilstein Fox coil overs and reservoir rear shocks, and maintains all factory TRD Pro suspension components. It is compatible exclusively with 2015 2021 Tundra

The ReadyLIFT Pro Plus 4 lift kit is specifically designed for 2015-2021 Toyota Tundra TRD Pro trucks, offering a 4-Inch front lift while retaining the original 2-Inch factory lift, equating to a total height similar to a 6-Inch lift on standard Tundras. This kit allows continued use of factory Bilstein/Fox coil-overs and reservoir rear shocks, and maintains all factory TRD Pro suspension components.

It is compatible exclusively with 2015-2021 Tundra TRD Pro models equipped with Bilstein/Fox coilover shocks, but incompatible with the TRD rear sway bar option and the factory front skid plate. The kit requires factory 20-Inch wheels and is not suitable for some factory 18-Inch wheels, though properly sized aftermarket wheels are acceptable.

The 44-5640 Pro Plus 4 inch lift kit features laser cut, CNC bent, welded, and boxed subframe drop assemblies that enhance suspension geometry and increase ground clearance by 2 inches. Its iron knuckles are CNC machined for a precise fit and allow retention of factory tie rods, eliminating the need for cutting or replacement.

The 4 inches of lift is achieved through offset top mount spacer design attached to the factory coilover/strut, ensuring a factory ride quality and maintaining the original track width. The kit includes a differential drop kit for easy installation and correct positioning of the differential, preserving optimal CV axle and drive line angles.

It focuses on maintaining proper alignment and geometry specifications, thereby reducing tire wear. The rear of the kit contains OEM-style cast iron rear lift blocks, longer u-bolts with hardware, bump stop extensions, sway bar frame mount brackets, and shock stem extensions for the Bilstein/Fox reservoir shocks.

The kit supports up to 35-Inch tires on a 9-Inch wheel with a +25 offset, minimizing the risk of rubbing. Removal of front mud flaps may be necessary depending on tire tread design.

Bathroom shelf
Color: Rustic Brown
Shelf will do the job where you have limited space. I do not like the waal anchors. They will leave a hole in the wall you might be able to crawl through.

These floating shelves are perfect! The wood looks rustic and beautiful, the guardrail keeps items secure, and installation was quick and easy. They’re sturdy, functional, and add the perfect farmhouse touch to my bathroom. Highly recommend!

Great little product
These are nice. They look really good. Nice metal accents with real wood. These are great. They went together pretty easily too. Anyone could do it. The only complaint I had about these is that I had to predrill the holes because they had not gone deep enough at the factory. They had small dimples where the screws were supposed to go. I had to make them actual holes with my drill. Not too bad though. Other than that they are awesome. You could even lightly sand and paint these to be any color you wanted. The metal brackets would pop right out and could be easily reinstalled after the paint dried. I like them a lot. They might be a bit smaller than I had imagined but they are as advertised. If you line up 3 rolls of TP that’s about exactly how big they are. Hope that helps. Take care.
