Sold as a pair made from one-half inch (0.5") plate contour cut steering arm end gusset. One inch (1.0") projection from radius of factory arm. Designed to prevent twisting the steering arm off when using large bore rams. These are sold as a pair. Notes: tire clearance will be an issue on most applications. Grinding or smoothing of gusset for tire clearance may or may not solve user/tire wheel combinations. Small "bump" on factory arm will need to be ground smooth.
