Prothane 4-1203-BL Dodge Truck Polyurethane Strut Arm Bushing Set

Prothane 4-1203-BL is a polyurethane strut arm (strut rod) bushing set designed as a direct replacement for worn or deteriorated OEM rubber bushings on Dodge trucks. Strut rods play a critical role in maintaining proper suspension geometry by controlling fore-and-aft movement of the lower control arm — keeping alignment in check under the dynamic loads of rapid acceleration, hard braking, and cornering.

Key Features:

• Manufactured from Prothane's high-durometer polyurethane compound for lasting performance
• Significantly more resistant to deformation, cracking, and deterioration than factory rubber bushings
• Restores and maintains proper suspension alignment and geometry
• Reduces suspension slop and improves steering response and handling precision
• Black (BL) finish to match the undercarriage environment
• Includes all hardware required for installation
• Direct OEM replacement fitment — no modifications required

Prothane polyurethane bushings are engineered to outperform the original rubber components that are prone to premature wear, compression set, and failure under stress. The 4-1203-BL is part of Prothane's extensive suspension bushing catalog, ensuring a precise fit and a noticeable improvement in vehicle dynamics for Dodge truck applications from 1972 through 1992.
