Frequently Asked Questions

What do you mean by "no adapter brackets"?
This caliper is a **true direct-fit** part. The mounting points are integrated directly into the caliper body and are designed to bolt to your truck's factory knuckle, just like the original. This provides a stronger, safer, and much simpler installation than universal kits that rely on extra adapter brackets.
Will this fit my stock 17" wheels?
Yes. This kit is specifically engineered to provide full clearance for the factory 17-inch and larger wheels on the GWM Tank and Cannon models listed, so you can get a huge performance boost without the expense of new wheels.
Why use a one-piece rotor on a truck kit?
For heavy-duty off-road and work truck applications, a solid one-piece rotor provides the ultimate in strength, durability, and reliability. It’s a simple, robust, and time-tested design for vehicles that demand absolute dependability in the harshest conditions.
