This is our brand new heavy duty professional roll fender reforming tool. Designed to slowly ease the wheel arch away allowing for larger wheels to be fitted. You may need to do so when upgrading to a larger tire, wheel, or even the addition of fender flares. It bolts directly to the hub flange, with elongated holes in the adapter plate to fit all popular 4 and 5 bolt hubs. The fully adjustable arm allows you to pull or push gradually.
