[More Info]
This Idler Arm Hardware Kit is a complete replacement set for 1961-1966 Chevrolet and GMC trucks and passenger cars. Designed to secure and properly align the idler arm to the steering linkage, the kit restores safe, precise steering by replacing worn or missing mounting hardware. Components are manufactured from corrosion-resistant steel with durable plating to ensure long service life under road and environmental exposure. Ideal for restorations, rebuilds, or routine maintenance, the kit helps eliminate play in the steering system, improves handling, and provides a reliable, easy-to-install solution for returning classic Chevrolet and GMC vehicles to safe roadworthy condition.
Features:
  • Fits 1961-1966 Chevrolet and GMC vehicles (truck and passenger car applications — verify specific chassis and steering type before ordering).
  • Complete idler arm mounting hardware set restores correct steering geometry and reduces play in the linkage.
  • Made from corrosion-resistant, plated steel for long-lasting durability and rust protection.
  • Includes nuts, bolts, washers, and bushings where applicable to fully secure the idler arm to the frame.
  • Direct replacement hardware for restoration projects, maintenance, or repair of worn/missing fasteners.
  • Easy to install with common hand tools; improves steering feel and vehicle safety.
Installation / Application:
  • Difficulty: 2/5
  • Estimated time: 30-60 minutes
Suggested Tools:
  • Socket set and ratchet
  • Torque wrench
  • Open-end wrenches
  • Breaker bar (if bolts are seized)
  • Penetrating oil

Instructions:
  1. Park vehicle on level ground, set parking brake, and lift the front of the vehicle using a jack; support securely on jack stands.
  2. Locate the idler arm on the frame and inspect the existing mounting hardware and surrounding components.
  3. Apply penetrating oil to corroded fasteners and allow time to soak if removal is difficult.
  4. Remove old nuts, bolts, washers, and bushings securing the idler arm using the appropriate sockets and wrenches.
  5. Clean mounting surfaces and inspect the idler arm and frame bracket for wear or damage; replace the idler arm if necessary.
  6. Position the idler arm and insert the new bolts from the kit through the frame bracket and idler arm mount.
