Prothane 6-301-BL Rear Control Arm Bushing Kit Black - Round Bushing

The Prothane 6-301-BL is a polyurethane rear control arm bushing kit designed as a direct performance upgrade over factory rubber bushings. This kit is engineered without shells, using round bushings that reuse the factory metal shells already in place on the vehicle.

Worn or deteriorated rubber control arm bushings allow excessive flex and movement in the suspension, degrading handling precision and causing alignment settings to shift under load. Prothane's polyurethane construction delivers a firmer, more dimensionally stable bushing that resists compliance flex and keeps the control arms located where they should be — maintaining accurate caster and camber settings over time.

Key Features:

• Premium polyurethane construction — firmer than OEM rubber for improved handling response and reduced suspension deflection
• Black color with graphite-infused compound — the graphite additive helps minimize noise and squeaking
• No-shell design — reuses existing factory metal shells for straightforward installation
• Round bushing configuration — correct for 1979–1993 Fox-body Mustang rear control arm applications
• Resists oil, heat, and environmental degradation — outlasts OEM rubber bushings significantly
• Includes Prothane Super Grease — supplied lubricant is critical for proper installation and squeak-free operation
• Covers both sides — one kit services the full rear suspension (left and right)
• Lifetime warranty — Prothane guarantees against defects in materials and workmanship for the life of original ownership
