MMR 5.0 Coyote GenX Dual Roller Secondary Chain & Sprocket kit

The new MMR GenX double row chain increases strength over 4 times that of a factory chain and the new MMR sprockets feature billet Steel construction with huge strength increases over the factory powdered metal cam gears! No more costly secondary chain failures on high revving and forced induction coyote engines and applications using 2 step rev limiters.

If you or someone you know is building a serious coyote engine this is a MUST HAVE! Same kit as included on the MMR GenX engines which produce over 4000hp and rev over 10,000rpm! Methanol and E-85 Compatible (guides will not soften and fail like the factory plastic) Kit includes parts to complete 1 engine. This kit ALSO inverts the driver side secondary tensioner (just like mmr part#467893) to correct it from tensioning the chain on the wrong side.

GenX Dual Roller Chains x2

*Timing Chains are a wearable item. They should be replaced EVERY racing season. See PN#467833 for replacement chains. To prevent the plastic guide from failing it has been replaced with a metal guide. This creates a metal on metal contact which will result in wear of both the chain and guide. This item can show  heat discoloration and wear pattern after initial break-in due to metal on metal friction and is no cause for concern. This is a heat treated steel part and moisture or human handling can cause minor surface rust (like a brake rotor), This does not affect performance of the item in ANY way and is no cause for concern.  CHAINS MUST BE SUBMERGED IN OIL PRIOR TO INSTALLATION. FAILURE TO DO SO MAY RESULT IN ACCELERATED WEAR & FAILURE!
