Steeda S197 Mustang Billet Rear Lower Control Arms – Spherical / Poly Ends
Steeda billet rear lower arms replace stamped S197 originals and reduce launch wheel hop. Claimed weight saving is over 6 lb/about 2.7 kg, reducing unsprung mass. Geometry includes the correct rear offset.
This 555-4406 version uses a spherical bearing at one end and Steeda polyurethane at the other. Recommended for applications above 500 hp, with a slight noise/vibration increase compared with all-polyurethane arms.
