Prothane 4-204-BL Front Control Arm Bushing Kit Black Without Shells

The Prothane 4-204-BL is a black polyurethane front control arm bushing kit designed as a direct upgrade over worn or soft factory rubber bushings. Engineered without shells, this kit is rated for use on vehicles up to 3,800–4,000 lb. axle with heavy-duty package applications, delivering improved suspension precision and long-term durability.

Worn rubber control arm bushings allow the front suspension geometry to shift under load, making it nearly impossible to maintain accurate caster, camber, and toe settings. Prothane's premium-grade polyurethane construction resists compression and deflection, locking your alignment settings in place and giving you confident, predictable handling.

Key Features:

• Premium polyurethane construction — significantly more durable and resistant to oil, ozone, and weathering than OEM rubber
• Optimum compliance resistance — minimizes unwanted bushing flex to preserve front-end alignment under load
• Without shells — designed for applications that do not require outer metal shells
• Precision fabrication — engineered for a proper OEM-style fit with no modifications required
• Includes super grease — specially formulated lubricant included for quiet, squeak-free operation
• Black finish — clean, professional appearance once installed
• Sold as a complete kit — everything needed for a full control arm bushing replacement

Prothane polyurethane suspension components are a proven upgrade for drivers who demand tighter handling response, longer service life, and consistent alignment retention compared to stock rubber bushings.
