Prothane 7-507 GM Polyurethane Motor Mount Large Clamshell - Red

The Prothane 7-507 is a premium-grade polyurethane motor mount designed as a high-performance replacement for worn or damaged factory rubber engine mounts on GM vehicles. Built to fit the large clamshell-style mounting configuration, this mount delivers the firm, reliable engine support that performance and street drivers demand.

Factory rubber motor mounts deteriorate over time, pulling away from their brackets and allowing excessive, potentially damaging engine movement. Prothane's polyurethane construction eliminates this problem by providing superior rigidity and durability far beyond what OEM rubber can offer, while still absorbing enough vibration for everyday drivability.

Key Features:

• Premium polyurethane construction — resists oil, heat, and age far better than OEM rubber mounts
• Application-specific engineering — precision fit for large clamshell GM motor mount applications; not a universal part
• Poly-locked "run-safe" design — limits engine travel and reduces the risk of breakage, so you can still get home even under hard use
• Precision fabrication — ensures accurate, repeatable fitment every time
• Super grease compatible — holds lubrication for quiet, squeak-free operation
• Reduces powertrain flex — keeps engine movement in check to improve throttle response and put more power to the wheels
• Signature red finish — classic Prothane color for a clean, performance-oriented engine bay look
• Lifetime warranty — Prothane guarantees against defects in materials and workmanship for as long as the original purchaser owns the vehicle

Whether you're building a street machine or a dedicated performance car, the Prothane 7-507 delivers the engine stability and longevity that OEM mounts simply can't match. Sold as a pair.
