How to Choose Wheel Spacer Thickness?


For a flush stance or off-road clearance, even small errors can lead to rubbing or premature bearing wear. This guide shows how to use the Straight Edge and Washer Test methods to protect suspension and steering travel. Learn how to find the exact size your build needs before ordering.
What Does a Wheel Spacer Actually Do?


Wheel spacers affect hub centricity, scrub radius, and bearing load. Even small thickness changes can optimize handling or create premature wear. For brake clearance or off-road use, this guide explains why forged 6061-T6 materials and proper torque are essential for reliable, safe operation.
