Prothane 6-1604 Ford Mustang Polyurethane Transmission Mount Kit

The Prothane 6-1604 is a heavy-duty polyurethane transmission mount kit engineered to replace worn factory rubber mounts on Ford Mustang and related Fox-body platform vehicles. Stock rubber transmission mounts are not built to withstand sustained performance driving, and as they deteriorate they introduce unwanted drivetrain slop, imprecise shifting feel, and increased stress on surrounding driveline components.

Key Features:

• Polyurethane construction — far more durable than OE rubber, resisting breakdown from engine oil, coolant, road grime, UV exposure, and other common under-vehicle contaminants
• Torque control design — engineered to limit excessive transmission movement and control torque for improved drivetrain response
• Poly-locked "run-safe" interlocking device — a unique safety interlock that keeps the mount together even under extreme stress, helping prevent the sudden failures common with stock rubber mounts
• Available in red or black — order the standard 6-1604 for red; use the 6-1604-BL suffix when ordering in black
• Direct-fit replacement — designed to match OE mounting specifications for straightforward installation
• Backed by Prothane's Lifetime Warranty — guaranteed free of defects in materials and workmanship for as long as the original purchaser owns the vehicle

Excessive transmission movement doesn't just affect shift quality — it can accelerate wear on driveshaft universal joints and, on many applications, cause unwanted exhaust system movement as well. Upgrading to the Prothane 6-1604 polyurethane transmission mount is one of the most effective ways to tighten up drivetrain feel, whether for street performance or track use.
