The factory bars are very brittle and cant handle the serious shock factors the rotary motor can deliver . The center bars are made from 300M material with our special heat-treat and double temper, rolled splines for extra strength, de-stressed and ready to install. This set comes with a complete 1 year warranty, and includes boots, clamps and grease.
