![Ridetech Delrin Control Arm Bushing Set 73-87 C10 with stock arms](http://shop.levelsevenmotorsports.com/cdn/shop/files/SBControlArmBushings_{width}x.jpg?v=1705331767)
OEM rubber control arm bushings allow too much deflection on the control arms. Poly bushings resist smooth rotation and impose stiction. Delrin bushings eliminate the deflection AND the stiction, leading to a huge improvement in both ride quality and handling.
