Upgrade your car's handling and steering response with this Energy Suspension polyurethane bushing kit. It replaces the soft, squishy rubber control arm bushings from the factory with their high-performance 'Hyper-Flex' polyurethane. Polyurethane is much more durable – it won't crack, rot, or deteriorate from oil and ozone like rubber does. The result is less deflection in your suspension, which means sharper turn-in, more precise steering, and better overall road feel. This specific kit (part #16.3105G) is designed for a specific vehicle (you need to check which one), and it comes in their signature Red color. The bushings are greasable for long-term performance. Installation requires pressing out the old bushings and pressing in the new ones, so some mechanical skill is needed. A popular upgrade for enthusiasts who want to tighten up their car's handling.
