Product Details

The Prothane 6-803 is a polyurethane rear frame leaf spring shackle bushing kit designed as a direct replacement for worn or deteriorated factory rubber bushings on 1957–1972 Ford, Lincoln, and Mercury vehicles. Prothane's proprietary polyurethane compound delivers significantly improved durability, handling precision, and chassis feedback compared to OEM rubber units.

Polyurethane bushings resist compression set, oil, ozone, and road chemicals that cause factory rubber bushings to crack and soften over time. The result is tighter suspension geometry, reduced axle wrap, and a more responsive rear suspension feel — whether on the street or at the strip.

Key Features:

  • Direct replacement for OEM rear frame leaf spring shackle bushings
  • Manufactured from Prothane's high-performance polyurethane compound
  • Resists oil, ozone, UV exposure, and road contaminants
  • Reduces suspension slop and improves rear-end stability
  • Longer service life compared to factory rubber bushings
  • Includes grease fitting for easy lubrication and extended wear
  • Available in Prothane's classic red polyurethane finish

Prothane 6-803 bushings are engineered for a precise OEM-style fit, making installation straightforward with standard hand tools. Ideal for restoration, performance upgrades, or routine suspension maintenance on classic Ford-platform vehicles from 1957 through 1972.

A+shipping was quick, communications were quick

Best prices online! Ordered a JBA performance exhaust and Airaid intake system for my 06 F-150. Was hesitant at first because I never heard of them but ordering was a breeze and saved me over $100 total for two items compared to anywhere else. Had package at my door in about 24 hours and even selected normal UPS ground shipping. Very satisfied and will definitely return!

Autoplicity was plenty cheaper than competitors for the springs I needed. I was shopping around and left the website after beginning a transaction and they sent me a coupon for 25% off shipping if I would return and purchase from them, which was cool. Unfortunately the coupon code didn't change the price and I didn't receive 25% off, but it was still cheaper than others.

Great!
