These Upgraded (HD) Heavy Duty Chains from MMR help eliminate the secondary chain failure on mildly modified 5.0 and 5.2 Coyote Mustang GT applications. The factory Coyote chains were never designed to handle the increased HP from other modifications placing them under extreme stress. These new Upgraded Coyote secondary chains feature stronger materials and construction giving you a direct OEM replacement performance chain. MMR Chains are so strong that we provide a lifetime warranty to the original owner against breakage, no questions asked! Be sure to choose the correct MMR chain for your application. If they are not from MMR they are not the "real deal"!The gram scale tells all and these are the heaviest most robust chains that fit the OEM sprockets- Period! Do not be fooled by the "Green Link" copycats offered by other companies, these chains do not provide ANY increased strength over factory chains and the gram scale confirms this!

*Timing Chains are a wearable item. They should be replaced EVERY racing season.
CHAINS MUST BE SUBMERGED IN OIL PRIOR TO INSTALLATION. FAILURE TO DO SO MAY RESULT IN ACCELERATED WEAR & FAILURE!
***NOTE*** NOT FOR USE IN ROAD RACE APPLICATIONS OR DRAG RACE APPLICATIONS THAT USE REV LIMITERS FOR STAGING!! The use of this product in those applications may result in CHAIN FAILURE! These Chains are NOT suggested for applications with aftermarket valve springs and/or camshafts. These chains are not suggested with the MMR Billet steel secondary chain guides (PN#467999) .For Drag Race applications YOU MUST USE MMR PN#567890R or PN#467890 GenX CHAINS/SPROCKETS. 95% of secondary chain failures are caused by choosing Incorrect chain for the application, seized camshafts or incorrect valve timing causing piston to valve contact. BE SURE YOU HAVE IDENTIFIED THE CAUSE BEFORE INSTALLING NEW CHAINS - IF NEITHER OF THESE ARE YOUR SCENARIO YOU SHOULD BE LOOKING AT MMR# 567890 or MMR#467890
