Detailed Description
This Dorman leaf spring assembly is specified for the rear of 1995-1998 Toyota T100 models and is built to restore spring support in the suspension system. The steel construction, 23.5 in. length axis dimensions, 31.5 in. length B, 1.524 pack thickness, and 6.875 in. arch length provide the dimensional details needed for application matching. Dorman 90-159 is a practical OE-style replacement for Toyota T100 rear leaf spring service where the original spring has lost ride height, load support, or stability.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Sagging rear ride height
- Reduced load-carrying support
- Rear suspension instability over bumps
- Uneven stance from worn spring packs
- Noisy or loose rear spring operation

Bushings are included, while mounting hardware is not listed as included. Confirm the Toyota T100 year, rear position, and suspension dimensions against the existing spring before replacement.
