Prothane 98-05 Lexus GS300 Rear Control Arm Bushings - Black. These direct-fit polyurethane bushings replace the factory rubber units on 1998–2005 GS300 rear control arms, offering increased durability and more consistent suspension response without requiring modifications.

Made by Prothane, these rear control arm bushings are engineered to resist wear, oil and road contaminants better than the original rubber components. They reduce unwanted deflection under load, helping deliver crisper handling and more predictable rear-end behavior during spirited driving. The black polyurethane construction is long-lasting and compatible with stock mounting hardware for a straightforward swap.
