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.

Only about 1.75 inches thick, and hard as a rock.
Size: 2.7"H (Standard)
This is nowhere near the 2.7 inches advertised. After waiting 4 days for it to expand, it never got higher than 1.75 inches from bottom to the highest point. Also, I'm not sure what kind of Talalay they claim to use; this was hard as a rock.

Great Pillow!
Size: King (Pack of 1)
Excellent product. I have been searching for a pillow that wasn't too soft or too hard and supported my neck. I now wake up without a stiff neck and a headache. Wonderful!
