Volkswagen Transporter Models T25/T3 Type 2 (Vanagon) All Models (1979 - 1992) Front Spring Upper Isolator - PFF85-1030 Standard rubber spring isolators sit between the coil spring and chassis to prevent any metal-on-metal contact between vehicle body and spring. Made from our Grey Shore 80A Polyurethane, our new PFF85-1030 Spring Isolator is designed to take OEM and aftermarket springs whilst outlasting and outperforming rubber alternatives. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
