WARRANTY UPGRADE -- Street Grade Polyurethane, Torq R6/R7 Rear Engine Mount (SURE0505, SURE0509)

Component(s):  Street Grade Polyurethane
Product(s):  Torq R6 (SURE0505) & Torq R7 (SURE0509) Rear Engine Mount
Application(s):  2006–2007 Mazdaspeed 6 & 2007–2012 CX7
Affected Date Range:  August 2011–November 2013

SUMMARY:  The smaller diameter bushing of the Torq R6/R7 fastens to the transmission case.  Heat from the transmission penetrates the Street Grade polyurethane bushings.  When exposed to heat over an extended period of time, the lifespan of the bushings was reduced (more information). 

CONCERN:  Due to exposure of extended cycles of heat, the Street Grade polyurethane bushings may fatigue at an accelerated rate.  Because of this, a reduction in performance or breakdown of polyurethane bushings can cause increased noise and vibration in the vehicle cabin. 

REMEDY:  SURE Motorsports will upgrade affected bushings to the new Class 1 polyurethane compound at no charge.  The Class 1 bushing is the new SURE Motorsports Street Grade polyurethane.  The Class 1 compound has improved rebound properties by increasing compression strength and material memory.  Heat tolerance has increased to 165 degrees Fahrenheit operating with a peak of 210 degrees.  This new bushing has accompanied new Torq R6/R7 Engine Mounts starting November 2013. New additional Class 2, Class 3 bushings will be available in 2014 for vehicles over 300 WHP.  

ACTION:  Inspect the Torq R6/R7 bushings for signs of fatigue.  Contact SURE Motorsports to process a warranty.

NOTES:  None
