ECS 4.0T Performance Engine Mounts

The C7 4.0T is notorious for eating stock fluid filled engine mounts with even the tamest tune. After extensive testing, we've designed a great poly engine mount to handle MOAR POWAH BABEH without too much added NVH! Our Engineering Manager sheered his stock passenger side engine mount while testing the ECS A2A prototype. This caused us to design a better mount while still maintaining drivability! Just like Goldilocks and the Three Bears - our first attempt was too hard, our second was too soft and the third was just right. We found that 40A durometer polyurethane was the optimal balance between NVH and stiffness. Poly bushings plus precision machined billet 6061-T6 housings with thermal isolators are a match made in 4.0T heaven. Also, because we go above and beyond we custom made error-free resistor harnesses. Grab a pair and enjoy crisper throttle response & more precise shifts!
