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. Must use part #R_SAGV as the "leg" of the gusset welds to the center of this plate.
