MMR Secondary Upper Chain Guide Billet Steel (2011-2023 Mustang GT) 467999

MMR Coyote Chain Guides are a must for all E-85/Methanol Applications. Unfortunately the 5.0 Engine was never designed for E-85 operation, the plastic secondary guides are softened quickly by chemicals contained in the E-85 and other fuels to the point of failure as shown below. Furthermore increased valve spring pressure and load from aftermarket camshafts and cams place the part under extreme load. This causes secondary chain failure and ultimately catastrophic engine failure. MMR has the answer for these applications with its new Heat Treated Billet steel guides.

 

The MMR guides eliminate this problem. The MMR chain guides are lubricated by oiling holes to prevent excessive wear and provide reliable operation for both street and strip vehicles.

 

These guides are suitable and recommended for Pump Gas, E-85, Race fuels and Methanol. 2 Guides included for 1 engine. Direct replacement.
