Prothane 7-2037-BL Total Polyurethane Suspension Bushing Kit - Black

The Prothane 7-2037-BL is a complete polyurethane suspension bushing total kit designed for the 1966 Pontiac GTO, Le Mans, and Tempest. This all-in-one kit replaces worn or deteriorated factory rubber bushings with high-performance polyurethane, delivering tighter handling, more consistent alignment, and significantly improved chassis feedback.

Prothane's polyurethane compound is firmer than OEM rubber, which increases bushing longevity and gives the suspension a measurable boost in handling performance. Unlike factory rubber that degrades from UV exposure, road grime, and vehicle fluids, polyurethane maintains its shape far longer — keeping your alignment angles secure and your suspension response predictable for the life of the vehicle.

Kit Includes:

• Ball Joint Boots
• Front and Rear Control Arm (C-Arm) Bushings
• Sway Bar End Links
• Tie Rod Boots
• Transmission Mount Kit
• Prothane Super Grease lubricant for installation

Black Polyurethane Color Note:

This kit is supplied in black polyurethane (suffix -BL). The black formula contains a small amount of graphite blended into the urethane, which can help minimize squeaking. Both red and black Prothane bushings share the same durometer hardness and deliver identical performance — proper lubrication at installation is the most effective way to prevent noise regardless of color.

All Prothane polyurethane bushings in this kit are made in the USA and are backed by Prothane's lifetime warranty against defects in materials and workmanship for as long as the original purchaser owns the vehicle.
