Superduty Leveling Carbon Spring Spacers Review

The spacers are great but the shock extensions need a little sanding and trimming. When I go to swap I will try to find longer shock absorbers.

The parts I received fit well, fasteners were missing, brake line brackets were missing and customer service is not responding to calls or emails. So be careful. I have contacted several times by email and phone but no response.

Warning! Note: This level kit messes up front suspension geometry that can only be attached with radius arm mounts. With this kit alone there is the very dangerous possibility of high speed oscillations. Suspension geometry needs to be corrected.

The part of the leveling kit that goes over the springs was simple and easy to install. They're doing the job I hoped they would. Unfortunately, I couldn't use butt extenders with all of this because the hole wasn't machined properly and the weld was crooked. This renders shock absorber extensions useless.

Overall quality sucks, some of the welds on the coil spacers are very sloppy and the shock extensions are slightly bent and too tight to fit on the bottom of the shock with no need to be hammered. The instructions do not indicate the orientation of how the stabilizer bracket extensions should be placed. They really must include a brake line extension bracket for it to say it's a full alignment kit. Update: Removed from truck due to rattling noise from improperly fitting brackets, this product…
