Description
A 1/2" rear spring spacer lift kit for the 2021–2026 Gen 3 Ford F-150 Raptor: CNC machined 6061-T6 aluminum plates that sit above the stock spring in the factory spring bucket. It raises the rear of the truck about 1/2" and adds preload to the rear spring.
If you carry weight in the back and the rear has settled, this brings the ride height back up. Because the plates sit directly above the spring, the body comes up by the same amount as the spacer thickness.
What Is In The Kit
- 1 set (2) of 1/2" spring spacer plates
- 1 set of longer mounting hardware
Why A Rear Spring Spacer
Rear ride height is set by where the spring sits and how much it is compressed. Add load to the bed or hitch and the spring compresses further, so the rear drops.
A spacer above the spring moves the top of the spring down relative to the body by the thickness of the plate. That adds preload to the rear spring and lifts the body by an even 1/2", using the stock spring and the factory spring bucket.
What it does not do
This kit will not improve wheel travel. Rear travel is limited by the shock, so the spacer adds ride height and spring preload, not travel.
How It Is Built
Made from 6061-T6 aluminum and CNC machined for a precise look and fit. The plates install above the stock spring in the stock spring bucket, using the longer mounting hardware in the kit.
Fitment
Fits the 2021–2026 Gen 3 Ford F-150 Raptor, rear suspension, with the stock rear spring.
Do not stack multiple kits to get more height. One kit per truck.
Installation
The plates install above the stock spring in the stock spring bucket. Longer mounting hardware is included.
Questions
How much lift does it add?
About 1/2" at the rear of the truck.
Will it give me more wheel travel?
No. Wheel travel is limited by the shock. The kit adds ride height and preload to the rear spring.
Can I stack two kits for 1"?
No. Multiple kits cannot be stacked to get more height.
Do I keep my stock springs?
Yes. The plates go above the stock spring in the stock spring bucket.
Will it help with a loaded-down rear?
Yes. If the rear sits low from carrying weight, the spacer helps bring the ride height back up.
