RENOSeat Spacers, Driver or Passenger Recline Lift Kit 3/4"-2.25" Compatiable with F150 2015+ / F250 F350 F450 Super Duty 2017+ Model - Lift up Front and Rear of Front Seat

I'm 6'2" and the stock F-150 seat is fine, but my wife is 5'4" and couldn't see enough to drive the truck.I raised both the passenger and driver side (2 sets) and she is very happy. (So I am very happy.)Others have pointed out that the dimensions are nominal. I did not check these. I put the Large blocks under the back and the Medium under the front of the seat(s). I did not stack or use the smaller blocks.Installation was simple. Both seats were done in about a half hour. Access to the stock installation was not difficult at all as it can be with some vehicles. Factory torque was also not as tight as I expected. Remove with 1/2" socket. But the installation bolts are long, which I suppose makes up for that. The replacement bolts (11/16" socket) are a good length for the installation and were easy to install. I didn't measure the torque, but I put them in tighter than the original factory bolts.Wife can confidently drive the truck now, and is much happier in the passenger seat also. The added height is not uncomfortable for me, although I do notice getting in and out of the truck is a little less comfortable while I'm getting used to not hitting my head on the truck with the taller seat.The truck is not my daily commute vehicle. I might prefer to have adjustable seats if it were, but for our weekend truck, very happy with the solution, and overall would recommend.

Ergonomics of the seat is so much better now

Great fit in my 24 f150

These are so easy to install. Literally just loosen some bolts. Put these in and tighten some bolts. Made for a much more comfortable driving position for my truck. I gave 4 stars because these are 3d printed out of some composite vs. being aluminum as they look in the photo.

I was too short to see over steering wheel of 2021 Ford truck. This fixed my problem!

The extra height added makes a huge difference in ergonomics. I can literally sit back and slouch and be lazy. I no longer feel like I’m sliding off the seat. I’m 6’3” and the cabin feels roomier by having a better sitting position.

I looked at the overall reviews instead of reading the one there. These are some kind of composite/plastic. I expected some type of metal. I'm sure they'll probably be okay, but it would be nice if the material was mentioned somewhere in the description. I used the smallest under the front of the seat to give my legs a little more support.

I orders these for a basic work truck with no seat adjustment. These work great if you want the front of the seat angled up to support your legs or if you're like me, rear of the front seat up so that there is no front angle cutting into my thighs. Easy to install and several ways to mix and match to achieve the height that best suits you. Great investment for comfort.
