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

The Prothane 4-104-BL is a 20-piece polyurethane body mount bushing kit engineered as a direct upgrade over worn or deteriorated OEM rubber body mounts. Replacing aged rubber body mounts is one of the most cost-effective ways to restore handling precision and reduce unwanted chassis flex in body-on-frame trucks.

Why Upgrade to Polyurethane?

• Superior durability: Polyurethane outperforms OEM rubber and resists breakdown from road grime, oil, and UV exposure
• Improved chassis rigidity: Firmer body-to-frame connection reduces flex for better handling response on- and off-road
• Long-lasting performance: Maintains shape and hardness far longer than factory rubber bushings
• Black with graphite infusion: The black formulation includes a small amount of graphite to help minimize bushing squeak
• Complete 20-piece kit: Includes all bushings needed for a full body mount replacement
• No grease required: Body mount bushings compress rather than rotate, so no lubrication is needed at installation

Prothane body mount bushings are manufactured in the USA and are backed by a lifetime warranty against defects in materials and workmanship for the original purchaser. A direct-fit design makes installation straightforward with basic hand tools.
