Afco Coil Over Spring 12"(H) x 2 5/8" I.D. 525 - 22525

• Chrome silicon wire (not chrome vanadium) used in every spring - not just certain rates - because of its higher tensile strength, longer life and ability to provide very consistent rates throughout a full range of wire sizes

• Cold wound on the latest automatic coiling equipment and heat treated twice during manufacturing to be able to withstand even the most abusive conditions

• Double ground ends for even better consistency and straightness

• Exclusive design and manufacturing process ensures sides of spring remain parallel when installed, so the spring won't rub hardware

• Protective coated instead of plated to avoid hydrogen embrittlement, which can shorten spring life

• Guaranteed for as long as you own them to remain within 2% of original free height

When AFCO set out to build coil springs, the design goal was simple: build the highest quality, best performing spring in the world, and back it with a lifetime guarantee.  Thousands of wins later, AFCOILS have set the standard in all forms of racing!
