FAQs

Q – Does this kit require cutting?

A – Yes. Because the axle is being lowered our kit does require some cutting of the driver’s side rear lower control arm bracket.  This is common among all full lift kits.  The top differential mount must be trimmed as well; again this is common with all knuckle style lift kits.

Q – I’ve heard tire wear can be an issue with lifted trucks, can I expect an issue with this lift?

A – No.  Tire wear is a definite consideration when choosing the right lift to purchase.  The difference between lift kits is not always visually apparent but can become apparent over a period of time and use.  Improper geometry of a lifted steering knuckle can result in accelerated tire wear and poor handling.  Our knuckles are designed so that there is no additional camber or toe change throughout the suspension cycle ensuring proper tire wear, tread life and exceptional handling.
