QA1's Level 2 front coil-over conversion for the C1500 integrates control arms with coil-over shocks to provide up to 4" drop (with the use of popular drop spindles; stock or 2" without) and allow room for wider wheels and tires. These systems include single adjustable QA1 Pro Coil systems so you can have ride height adjustability and change the valving to meet your specific needs. All QA1 shocks are 100% dyno tested and serialized. Coil-over hardware and all required nuts, bolts, etc. are included. Made in the USA.
For the Level 3 system, offering up to 6" drop in the front with drop spindles, see part 52613-D600. That is the perfect match for OBS owners with competition in mind while still allowing adjustability to cruise to the track in comfort.
