Detailed Description

This Dorman 90-131 leaf spring assembly is a direct replacement for rear suspension applications on the Toyota Pickup. It is engineered to restore spring tension and help return the vehicle to proper ride height after the original leaf spring has weakened from age, corrosion, or repeated load cycles. The steel construction, 1545 load rate, and 7.5-inch arch length support consistent rear suspension performance for the listed fitment.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. The Dorman 90-131 is a practical replacement choice when the rear suspension needs renewed support without axle modification.

What It Helps Fix

  • Sagging rear suspension
  • Rust-damaged or fatigued leaf springs
  • Reduced rear ride height
  • Poor load support at the rear axle
  • Loss of spring tension in a Toyota Pickup rear suspension

Installation Notes and Tips

Mounting hardware is not included, so reuse or source the correct hardware as needed for the application. Confirm the listed Toyota Pickup rear notes, including 1/2 ton capacity and pack thickness requirements, before service.

Quality Assurance
