Racers using multileaf springs realize the importance of accurate arch, load capacity, and durability. AFCO Leaf Springs are the highest quality racing springs available and give you features not available in any other leaf spring. Lightweight IMCA Modifieds to heavy stock cars — AFCO has the correct springs. Our chrome-vanadium alloy spring steel material is superior to others and provides consistent rates over a longer life span. Teflon rub blocks between leafs reduces friction and maintains consistency of rate. Tapered leafs reduces stress by 30-40% and prevents loss of arch. Shot-peened after arching to reduce tensile stress provides 3 - 5 times more service life to the spring. Chrysler or Camaro style. Front bushing included.
