SUMMARY: Torq R3 Street Grade polyurethane bushings were rated for up to 275WHP (more information).
CONCERN: Street Grade polyurethane in aggressive or over-powered applications may result in a shorter bushing lifespan. Reduced performance and breakdown of polyurethane bushings may increase noise and vibration in the vehicle cabin.

The Class 1 compound has improved rebound properties by increasing compression strength and material memory. This upgraded bushing went into Torq R3 Engine Mounts starting August 2013. New additional Class 2, Class 3 bushings will be available in 2014 for vehicles over 300 WHP.
ACTION: Inspect the Torq R3 bushings for signs of fatigue. Contact SURE Motorsports to process a warranty.
