Product Description

The Fox 398-00-370 is a 3.60" large bore spanner wrench designed for adjusting spring preload and ride height on Fox Performance Series and Podium Series coilover shocks equipped with locking spring preload rings. The wrench engages the preload ring notches to allow easy, precise adjustment of coilover spring seat position without damaging the shock body or preload ring. Sized at 3.60" for Fox 2.5" and 3.0" body coilovers -- verify your coilover's spanner ring diameter before ordering.

Built from heavy-duty steel for durability and reliable engagement under load. This is a universal tool and is not vehicle-specific -- it works with any Fox coilover application using the 3.60" preload ring diameter, including UTV, off-road truck, and automotive coilover setups. For Fox coilovers using the smaller 3.20" preload ring, use Fox 398-00-378 instead. An essential tool for any Fox coilover owner who needs to adjust ride height or spring preload for tuning, seasonal changes, or track setup.
