This fork stabilizer, also known as tweak bar or fork truss, is truly a performance part. It dramatically improves front-end handling on any stock Harley. The engineering design and sleek styling are obvious characteristics in this part. The compound arc, which sweeps upward and rearward simultaneously, imparts greater resistance to deflection, twisting and bending on the front fork. The upward arch also provides additional fender clearance. The addition of large diameter holes spaced out to a maximum strength calculation helps keep unsprung weight to a minimum. Installation is very simple and the disassembly of the front-end is not necessary. All the trusses are designed to bolt securely to the lower sliders including factory chromed models. Trusses are machined out of solid billet aluminum and have a chrome finish.
