Prothane Motor Mount Insert Bushing - Red

Upgrade the engine support in your classic GM truck or van with the Prothane Motor Mount Insert Bushing in red. Engineered for a wide range of 1984-1997 Chevrolet Astro, 1985-1997 GMC Safari, 1988-1997 Chevrolet S10, and 1988-1991 GMC S15 models, this insert is designed to replace the stock rubber mount and significantly reduce engine movement.

Benefits of Prothane Motor Mount Inserts:

  • Reduced Engine Rock: Effectively minimizes engine vibration and torque-induced movement, leading to a more stable platform during acceleration and cornering.
  • Enhanced Performance: By keeping the engine securely in place, it improves throttle response and power transfer to the drivetrain.
  • Durable Polyurethane: Constructed from Prothane's high-performance polyurethane, offering superior resistance to heat, chemicals, and wear compared to OEM rubber.
  • Direct Fit Design: Precisely manufactured to fit into the factory motor mount, ensuring a hassle-free installation.
  • Performance Red Color: The bright red hue adds a custom touch under the hood.

This motor mount insert is an excellent choice for owners looking to restore or enhance the performance and feel of their vehicle. It's particularly beneficial for trucks and vans that experience heavy use or have had their original mounts degrade over time. The improved stability contributes to a more controlled driving experience, whether you're towing, off-roading, or simply cruising.

Ensure your engine is firmly planted and ready for action with Prothane's quality polyurethane solutions. Find this and other essential upgrades at GGCRACING.COM.
