Prothane 12-402 Rear Sway Bar End Link Bushing Kit 1986-1988 Mazda RX-7

The Prothane 12-402 is a rear sway bar end link bushing kit specifically engineered for the 1986–1988 Mazda RX-7. Manufactured from Prothane's signature red polyurethane compound, these bushings deliver significantly improved durability, chassis responsiveness, and handling precision compared to OEM rubber components that degrade over time.

Polyurethane end link bushings resist compression, cracking, and deterioration caused by oil, road chemicals, and heat — common failure points with factory rubber bushings. Upgrading to Prothane's poly bushings reduces slop in the rear stabilizer bar linkage, resulting in more direct cornering feel and improved body roll control.

Key Features:

• Direct OEM replacement fit for 1986–1988 Mazda RX-7
• Premium polyurethane construction for extended service life
• Resists oils, road salts, and extreme temperatures
• Improves chassis feedback and reduces suspension slop
• Includes all hardware needed for installation
• Prothane red polyurethane finish for easy identification

Prothane has been a trusted name in performance suspension components for decades, offering polyurethane bushing solutions for a wide range of domestic and import vehicles. The 12-402 kit is a straightforward upgrade for RX-7 owners looking to restore or enhance rear end stability.
