Product Details

The Prothane 7-1904-BL Motor/Transmission Mount Combo Kit replaces worn factory rubber mounts with high-performance black polyurethane to deliver tighter engine control, reduced drivetrain slop, and improved power transfer to the wheels. Unlike generic universal mounts, this kit is engineered for a specific application to ensure a precise, factory-correct fit with a noticeable performance upgrade.

Key Features:

  • Application-Specific Engineering: Designed to exact OEM mount geometry for a direct, no-modification installation
  • High-Performance Polyurethane Construction: Significantly firmer than stock rubber mounts, minimizing engine and transmission movement under load
  • Poly-Locked "Run-Safe" Design: Built-in travel limiter retains the drivetrain even under extreme stress, so you can safely get back home if a mount is overloaded
  • Reduced Drivetrain Breakage: Limits excessive mount travel that can lead to damaged CV axles, shift linkage, and exhaust components
  • Maximum Power Transfer: Less mount deflection means more of your engine's torque reaches the wheels instead of being lost to drivetrain flex
  • Black Polyurethane Finish: Resistant to oil, grease, solvents, and ozone for long service life
  • Complete Combo Kit: Includes both motor mount and transmission mount inserts/bushings for a full drivetrain mount refresh

Prothane polyurethane motor and transmission mounts are a direct upgrade for performance street driving, autocross, and track use where engine stability and responsive power delivery are critical. Each kit includes all necessary hardware and detailed installation instructions.

Shopping was quick and easy with the link to Amazon to pay.

Autoplicity had the best price on an ARB locker. They shipped it quickly but was not able to give me the tracking number until after I had already received it.

Window motor and regulator was the best price around! Shipping was quick, and it was exactly the part I ordered. I will definitely be ordering again from Autoplicity!

Quick ordering, cheap prices, and an easy, excellent online shopping experience. Hence why I ordered again. Could work on shipping costs though.
