Mevotech SMS81412 Front Coil Spring Set

Mevotech SMS81412 is a front coil spring set for select Toyota Sienna applications. It is a constant-rate coil spring for vehicles that require a direct suspension spring replacement at the front axle.

Key Features

  • Front coil spring set for suspension service
  • Constant-rate spring design for consistent front-end support
  • Direct replacement for select Toyota Sienna models
  • Mevotech part number SMS81412
  • Cross-references Dorman - HELP 81412 and Gates 20878 for the same application

Application Details

Compatible with 2007-2010 Toyota Sienna, front. This Mevotech SMS81412 coil spring set is used in front suspension repair where the original spring has weakened, sagged, or lost proper ride height. It also serves as a replacement option for Toyota Sienna front spring service across the listed model years.

Common Reasons for Replacement

  • Front ride height has dropped
  • Uneven stance or suspension sag
  • Noise from worn or fatigued front springs
  • Reduced suspension support after spring wear
  • Restoring proper front suspension geometry after spring failure

Installation Notes

Install on the front suspension only for the listed Toyota Sienna applications. Verify year, model, and position before ordering, and compare the original spring shape and dimensions to confirm proper replacement. Because coil spring service affects suspension preload, professional installation and proper spring compression equipment are recommended.

Quality Assurance

Mevotech SMS81412 is built as a constant-rate coil spring replacement for the specified front application. Confirm fitment against the vehicle listing before installation.
