KINGROCK KR-4301 Rear Coil Spring Isolator — Ram 1500

Replace a worn or damaged spring isolator with the KINGROCK KR-4301. Positioned between the rear coil spring and its seat, this isolator helps limit metal-to-metal contact and the resulting noise and vibration.

It is suitable for restoring the spring seating interface during suspension maintenance or rear coil spring replacement on compatible applications.

Features and Benefits

  • Spring isolation: separates the spring from its seating surface to help limit metal-to-metal contact.
  • Noise and vibration reduction: helps maintain proper isolation between the spring and its seat.
  • Replacement for the existing isolator: allows a worn, cracked or deteriorated component to be replaced.
  • Classic-style spring installation on a Ram DT: allows this installation when the application is approved by the spring manufacturer.
  • Sold individually: allows a single isolator to be replaced as needed.

  • KINGROCK part number: KR-4301.
  • Product type: rear coil spring isolator.
  • Equivalent OEM reference: Mopar 68273964AB.

Compatibility

For Ram 1500 models equipped with rear coil spring suspension, on applications matching the listed OEM reference. Verify the vehicle configuration and compatibility with the original part before installation.

Installing Classic-style springs on a Ram DT

KINGROCK KR-4301 isolators allow Ram 1500 Classic-style rear coil springs to be installed on a Ram 1500 DT when this application is approved by the spring manufacturer. Matching isolators are required for this installation, including with TufTruck TTC-1223VT springs.

Two isolators are required, one per spring. Sold individually.

Installation

Install in the original isolator location. Clean the seating surfaces and ensure that the isolator and spring are correctly positioned before loading the suspension. Follow the vehicle manufacturer’s service procedure and, when replacing the springs, the spring manufacturer’s instructions.
