QA1 2-1/2in ID High Travel Spring - 7in Length x 850lbs/in - Black Powder Coated

The QA1 7HT850B is a 7-inch high travel coil spring designed for performance suspension systems. It features a 2-1/2 inch ID and a 850 lb/in spring rate, manufactured from high-tensile, chrome silicon alloy spring wire. This construction allows for fewer coils, a smaller wire diameter, and lighter weight, resulting in increased travel and faster suspension reaction.

Made in the USA, these springs are finished in black powder coat and are lifetime guaranteed to remain within 2% of their original free height and rate under normal operating conditions. Changing coilover spring rates can be beneficial for adapting a vehicle to different driving styles, from daily driving to track days.
