Dorman 90-555 Rear Left Leaf Spring

The Dorman 90-555 leaf spring assembly is a steel suspension replacement for the rear left side of select Toyota Tundra models. It is built to restore ride support, payload handling, and suspension control when the original leaf spring has sagged or worn.

Fits 2019-2021 Toyota Tundra, rear left. Fits 2012-2018 Toyota Tundra, rear left, including Double Cab, CrewMax, and Double Cab without Off Road Package configurations listed below.

  • Steel leaf spring assembly with a standard suspension grade design
  • Rear axle orientation for the left side
  • 4-leaf construction with a 2.375 in. leaf width
  • Load rate: 1450
  • Black bushings included
  • End 1: Berlin eye; End 2: up turned eye
  • Leaf spring arch length: 5.75 in.; pack thickness: 2.2 in.
  • Length B: 32 in.; length axis 1 and 2: 31.375 in.

This leaf spring assembly is built for Toyota Tundra rear suspension service where the original spring has lost height, developed uneven stance, or no longer supports cargo and trailer weight evenly. The Dorman 90-555 follows the listed OE-style dimensions and attachment points for the rear left position, helping maintain suspension geometry on 2019-2021 Toyota Tundra Double Cab and 2012-2018 Toyota Tundra Double Cab and CrewMax applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems It Can Address

  • Rear sagging from a fatigued leaf spring
  • Uneven ride height on the left rear corner
  • Reduced load support in the Toyota Tundra rear suspension
  • Excessive bounce or poor rear-end control over bumps
  • Noise or looseness related to worn spring bushings

Installation Notes and Tips

Verify rear left fitment against the vehicle’s cab configuration and model year before installation. Compare the spring’s length, arch, pack thickness, and eye orientation to the original part to confirm proper alignment. Inspect related suspension components, including shackles, U-bolts, and mounting points, for wear or corrosion before reassembly.

Quality Assurance

Dorman supplies this leaf spring assembly as a standard replacement suspension component for the listed Toyota Tundra applications. The part number is 90-555, and the design follows the specified material, dimensions, and attachment style for direct-fit service on confirmed rear left fitments.
