Prothane 4-104 Polyurethane Body Mount Bushing - Kit 20-Piece

The Prothane 4-104 is a complete polyurethane body mount bushing kit engineered to replace worn, deteriorated OEM rubber body mounts. Designed for the Dodge D50 pickup (1979–1987) and Mitsubishi truck pickup 2WD (1983–1990), this 20-piece kit delivers a significant upgrade in durability, rigidity, and long-term performance over factory rubber components.

Why Replace Your Body Mounts?

Factory rubber body mounts are vulnerable to degradation from engine fluids, UV exposure, road grime, and general wear and tear. As these bushings break down, the body-to-frame connection weakens — leading to alignment issues, sagging body panels, doors and hoods that won't latch properly, and an increasingly rough, noisy ride. The Prothane 4-104 kit directly addresses these failure points.

Key Features:

• Prothane Performance Polyurethane — resists road grime, UV rays, and fluids that destroy rubber over time
• 20-Piece kit — includes all necessary bushings and washers for a complete body mount replacement
• Improved rigidity with enough resilience to maintain ride comfort on both street and off-road use
• Available in red or black — both colors share the same durometer hardness and performance characteristics
• Made in the USA — backed by Prothane's lifetime warranty against defects in materials and workmanship

Kit includes bushings and washers. Note: additional installation hardware (bolts, sleeves) is not included. Prothane polyurethane body mounts are a proven, cost-effective upgrade for restoring proper body-to-frame alignment and extending the life of your truck's chassis connection.
