Prothane 7-1004 Red Rear Leaf Spring Eye and Shackle Bushing Kit

The Prothane 7-1004 is a premium-grade polyurethane leaf spring eye and shackle bushing kit engineered to replace worn or deteriorated OEM rubber bushings in leaf spring suspension systems. Leaf spring pivot points and shackles are subjected to significant and constant forces during normal driving, making bushing condition critical to suspension performance and stability.

Unlike factory rubber bushings, Prothane's polyurethane construction resists breakdown from oils, road salt, chemicals, and atmospheric contaminants such as ozone and smog — delivering a longer service life and more consistent suspension response. Each kit includes precision-fabricated metal sleeves and all necessary hardware to ensure a correct, rattle-free fit.

Key Features:

• Premium polyurethane construction — resists deterioration from oils, road chemicals, and environmental exposure
• 1-3/8 inch OD frame shackle bushings for accurate fitment
• Precision-fabricated metal sleeves included for a perfect, secure fit
• Super Grease included — synthetic lubricant pre-packed to ensure quiet, squeak-free operation
• Complete kit — includes all bushings, sleeves, and hardware needed for installation
• Firmer suspension feel reduces vague or mushy handling associated with degraded rubber bushings
• Lifetime warranty against defects in materials and workmanship for the original purchaser

The Prothane 7-1004 is available in red and installs using standard hand tools. Be sure to apply the included Super Grease thoroughly to all bushing surfaces during installation to prevent noise and ensure long service life.
