Product Details
Deaver Progressive Series springs are high-quality, 8-leaf, 9-leaf, 10-leaf, 11-leaf, and 12-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. Our progressive system spring’s even, linear compression rate curve is the primary key to excellent ride quality. Other design features include full military-wrapped spring eyes for superior durability, diamond-cut inner leaf ends minimizing shear points, and anti-friction pads inserted between the leaves for a smoother ride and quiet operation.
