The KellTrac Spec Viking Berserker Rear Coilover Kit for the 2005-2014 Mustang is engineered for cars that are primarily street-driven but built for racing. Designed with street, strip, prep, and no-prep racing in mind, this coilover kit features KellTrac spec'd spring rates, shock shaft travel, compression, and rebound valving that are optimized for S197 SRA applications and the racing style of your choosing. If you're driving your Mustang daily but also taking it to the track, this is the kit for you.

The Berserker series is built for cars that juggle their 20+ mile daily commute with racing at the track. If you're looking for a coilover kit that can handle both street driving and aggressive racing conditions, this is the solution. No other company has helped more street-driven Mustangs hit 1.19 or better sixty-foot times than KellTrac.

This kit is custom-designed for those who demand precision and performance. For best results, we recommend pairing it with KellTrac Caster Camber Plates (available separately). The kit also includes thrust bearings and a spanner wrench upgrade option to make installation easier.
