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.

Buttons
Size: King, Color: Dark Grey
Here's what I like: Appearance. I like the color and how it looks on my bed. It looks appropriate for a king sized bed. Removable cover. It was easy to take the cover off and wash, which I appreciate because I like my bedding to smell fresh and clean. What I don't like: It is a bit softer than I would like. But I can live with it. I thought it was a foam pillow inside, not fill. Maybe my fault though for not reading description or reviews. Quality. This is the biggest issue driving the rating. I removed the over upon opening the item so I could wash it. The buttons are attached the the inside cover. When removing the outside cover, you have to unbotton them. They are not secured well at all. From what I can tell the threading goes through the inside cover through the fill to the button on the opposite side. I suspect this because 4 buttons came off when I removed the outside cover. They are very loosely secured to each other. Be gentle when removing and replacing the cover. Now I will have to thread the buttons again and secure it. Just a pain for a brand new item. Should I expect that for the cost of the item? I dunno. Could have been a higher rating, but, damn those buttons.

Nicer than the pictures!
I bought this for my wife for Christmas and it’s been a game changer for watching TV in bed. I was always having to double up on pillows and having to adjust them because they’re down and kinda deflate lol. The green color is super pretty too! Quality so far has been really good!

Pretty, but very practical.
Size: Full, Color: Mint Green
The color was exactly what I expected from the photo. It arrived in an unbelievably small package, but expanded quickly once I opened the bag. I waited the recommended 24 hours to be sure it was done. I am pleased that the length is a perfect fit, and I like that it comes up to the back of my neck when I'm sitting in bed. It is a bit softer than I originally imagined, but not so soft that I feel like I'm sinking through it. It's very pleasantly supportive. The fabric is like a soft ribbed corduroy with piping along the outer seam. It looks nice. Both ends have a pocket that is barely noticeable, but is the perfect size to keep your phone close by. I'm temporarily homebound and spending a lot of time sitting in bed, so I'm very glad I invested in this pillow for comfort and convenience. If you ever have trouble with pillows working their way under the edge of the headboard, and into the dusty space between the headboard and the wall, consider this problem solved.

Measure your bed and space, I did and ordered the perfect fit!
Size: Queen, Color: Navy
Love this wedge pillow. I bought it for our boat stateroom bed. It fits perfectly as beds on a boat are always odd sizes. It is very comfortable allows me to sit up in bed to read. Also keeps our bed pillows from sliding back. Good quality, color and size.

Comfy, Supportive, and Great for Lounging in Bed
This wedge-style headboard pillow has made sitting up in bed much more comfortable. The shape offers full upper-back support, with just the right amount of firmness to keep you propped upright without feeling stiff. It’s especially helpful for reading or watching shows in bed, and it stays in place well against a flat headboard. The purple color is rich and vibrant in person, and the removable cover is soft to the touch with a smooth finish. We really appreciated that the cover zips off easily and can be machine washed—it held its shape and color after laundering. The pillow also has a nice weight to it, so it doesn’t feel flimsy or slide down easily. This is a great addition for anyone who likes spending time sitting up in bed, whether for reading, working, or relaxing. It also doubles nicely as a decorative accent when the bed is made. The quality feels solid, and the size works well across the width of a queen bed without overwhelming the space. Id say it is ok for the price. It does retain warmth though
