Prothane 7-805 Frame Shackle Bushing Kit Polyurethane 1-3/8in OD Red

The Prothane 7-805 is a premium polyurethane frame shackle bushing kit designed to replace worn or failed OEM rubber bushings in leaf spring-type suspension systems. Leaf spring pivot points and shackle mounting locations are subjected to intense, repetitive forces during normal driving and load-bearing — making bushing quality critical for ride control, handling, and long-term durability.

Factory rubber bushings are prone to premature deterioration from road grime, UV exposure, and mechanical stress. Once failed, suspension vagueness, clunking, and reduced load capacity are common symptoms. Prothane's premium-grade polyurethane compound offers significantly greater resistance to wear, oil, road contamination, and compression set compared to OEM rubber.

Key Features:

• Premium-grade polyurethane construction — firmer and more durable than factory rubber
• 1-3/8 in. outer diameter frame shackle bushings
• Precision-fabricated sleeves included for accurate fit and proper installation
• Resistant to road grime, oil, and environmental degradation
• Red polyurethane finish
• Made in the USA
• Backed by Prothane's lifetime warranty against defects in materials and workmanship

Each kit includes all necessary bushings and hardware sleeves for a complete installation. Apply the supplied Prothane Super Grease to all bushing surfaces during installation to ensure quiet, long-lasting performance. Note: Multiple shackle bushing configurations exist for common applications — verify the 1-3/8 in. outer diameter matches your frame shackle before ordering.
