Product Details

The Prothane 18-1004 is a premium polyurethane leaf spring eye and shackle bushing kit designed to replace worn or deteriorated OEM rubber bushings in leaf spring suspension systems. Leaf spring suspensions place significant stress on pivot points and shackle mounting locations, causing factory rubber bushings to compress, crack, and fail over time—resulting in loose, sloppy handling and increased body roll.

Prothane's polyurethane compound outperforms OEM rubber in durability, resistance to oils and solvents, and the ability to maintain consistent deflection rates under heavy load cycles. The result is improved steering response, reduced axle wrap, and a more precise suspension geometry that holds up over the long term.

Key Features:

  • Premium-grade polyurethane construction for superior longevity over OEM rubber
  • Resists compression set, oil, grease, and road chemicals
  • Precision-fabricated sleeves and hardware included for a perfect, rattle-free fit
  • Restores proper suspension geometry and reduces axle movement
  • Direct replacement for factory leaf spring eye and shackle bushings
  • Manufactured by Prothane, a trusted leader in polyurethane suspension components

This kit includes all necessary bushings, sleeves, and related hardware for a complete installation. Prothane 18-1004 is an ideal upgrade for drivers seeking improved suspension performance and durability over stock rubber components.

Autoplicity was great, I ordered my springs late Monday night and I received a shipment order confirmation number early Wednesday. So basically 1 business day and my order was out the door, pretty impressive. Can't wait 'till it gets here! Thanks Autoplicity!

very good, for my first time .

Best price I could find after hours of searching, I recommend 100%!!!

They had the best price on a hitch I was looking for and the shipping was fast also. The hitch was shipped bare except for taping the box of bolts to it thus leaving the hitch open and chipping the paint/powdercoating in quite a few places which I had to touch up before installing.

Easy to use website. The belts I ordered didn't have a picture but I knwew what I was looking for.
