The factory rubber subframe bushings are very compliant, allowing the unibody to flex independent of the front subframe. Polyurethane or aluminum are commonly used to replace the stock rubber, but not without compromise. Poly tends to squeak and aluminum will transmit NVH (noise, vibration and harshness). The Ridetech Subframe Bushing Kit uses a combination of Delrin and Aluminum components to reduce chassis flex while providing some protection from NVH. These bushings are the same height as the stock bushing and include all new Grade 8 hardware.
Works great with the Ridetech subframe connectors!
