The "BTF Jeep TJ Competition Corners" are laser cut from 3/16" high-strength steel plate. They are then roll formed to the correct radius on a CNC roller. These comp corners will allow rear wheelbase stretches of up to 8" and clear 42" tires with no rubbing. You will be able to rub trees and rocks with little or no body damage. They are also handy to cover old trail damage. Like all of the BTF Comp Corners the TJ corners will be shipped counter-bored and include stainless steel hardware for a smooth appearance.
