Deaver Progressive Series springs are high quality 9-leaf and 10-leaf units fabricated with high grade 5160 "American Made" steel. A higher leaf count spring allows the use of thinner leaf material that yields a more flexible progressive leaf stack, or pyramid, producing a much smoother spring rate curve throughout the complete suspension cycle. The even, linear compression rate curve of our progressive system spring is the primary key to excellent ride quality.
NOTE: AFTERMARKET SHACKLE REQUIRED
KEY FEATURES:
