Prothane 7-508-BL Black Polyurethane Motor Mount Set LT1 V8 F-Body

The Prothane 7-508-BL is a black polyurethane motor mount set engineered specifically for 1993–1997 GM F-Body vehicles equipped with the LT1 V8 engine. Sold as a pair, these mounts are a direct, application-specific upgrade over soft factory rubber motor mounts, delivering firmer engine support and improved power transfer to the drivetrain.

Key Features:

• High-Performance Polyurethane Construction: Crafted from specially formulated polyurethane that resists oil, chemicals, heat, and road contaminants that degrade stock rubber mounts over time
• Application-Specific Engineering: Designed exclusively for 1993–1997 F-Body LT1 V8 applications — not a universal fit — ensuring precise fitment and maximum performance benefit
• Poly-Locked "Run-Safe" Design: Features an internal interlocking safety mechanism to limit engine travel and reduce the risk of mount failure under hard driving conditions
• Limits Engine Movement: Reduces excess engine travel to improve throttle response and put more power to the wheels
• Black Colorway (7-508-BL): The black formulation includes a small amount of graphite blended into the polyurethane, which can help reduce squeaking; proper lubrication with the included pre-lube at installation is recommended
• Also Compatible with LT1 Swap Builds: May be used in universal LT1 engine swap applications when paired with 1993–1997 F-Body style clamshells
• Lifetime Warranty: Backed by Prothane's lifetime warranty against defects in materials and workmanship for the original purchaser

Sold as a pair. Hardware included. Made in the USA. Note: Filling the voids in OEM-style mounts with polyurethane may result in an increase in NVH (noise, vibration, and harshness) compared to stock rubber mounts — a typical trade-off accepted by performance and enthusiast drivers.
