Description
Overview
QA1 Level 2 Big Wheel Kit BW02-GMB6 pairs front and rear wheel tubs with adjustable suspension components for the applications listed on the product page. The package includes a QA1 adjustable front coilover conversion and QA1 adjustable rear shocks. Its published capacity is up to 18 x 11 in. wheels at the front, up to 20 x 12 in. wheels at the rear, and tires up to 315 mm wide. The tubs are listed as high-strength steel with a black powder-coat finish.
The package is intended to address both clearance and suspension changes in one project. The page describes the wheel tubs as providing clearance for the stated wheel and tire sizes, while the Level 2 configuration adds the adjustable front coilovers and rear shocks. It also says these components allow adjustment of ride height and damping. Exact final tire size remains dependent on the selected wheel width and backspacing.
This is a fabrication-based suspension and clearance upgrade rather than a simple add-on. The product page states that installation includes cutting factory sheet metal, welding the new tubs in place, and modifying the suspension system. Plan the project around the wheel and tire package you intend to use.

Buyer guidance
Choose BW02-GMB6 when your build calls for the wheel and tire capacity published for this Level 2 package and you are prepared for the required metalwork and suspension changes. Use the published front and rear wheel capacities as planning limits, not as a substitute for checking your own wheel specifications. The stated 315 mm tire capacity is a maximum listed by the page, not a confirmation that every wheel and tire combination will fit.
Before final assembly, test-fit the specific wheel-and-tire combination. The product page notes that exact fit depends on wheel width and backspacing. Account for the work involved as well: the page says installation requires cutting factory sheet metal, welding the tubs in place, and modifying the suspension. It strongly recommends professional installation, while noting that experienced DIY installers with fabrication skills may carry out the work. Confirm vehicle application and component needs before ordering.
