Help support your minivan's front end and absorb road impacts with the Mevotech Supreme coil spring set, part number SMS81414. This front coil spring set is cataloged for the 2007-2010 Toyota Sienna. See the "Vehicles it fits" section for engine-level fitment details.
Coil springs support the vehicle's weight, set its ride height, and compress to absorb road impacts. They work together with the shocks or struts to help keep the tires in contact with the pavement. Key features of this set:
- Constant-rate spring profile: Designed to deliver a consistent spring rate as the coil compresses.
- High-grade alloy steel: Heat treated and annealed for high strength.
- Corrosion-resistant surface treatment: Helps prevent rust buildup for longer service life.
- Front position: Cataloged for the front suspension of the listed applications.
Signs a front coil spring may need replacing include sagging or uneven front ride height, a lean to one side, bottoming out over bumps, clunking from the suspension, or a visibly cracked or broken coil. These symptoms can have other causes, so diagnose the suspension before ordering parts. Coil springs store significant energy, so follow the vehicle service procedure and use proper spring-compression tools during installation.
