Deaver Progressive Series springs are high quality 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.
The Expedition Leaf Pack provides additional payload capacity for all your gear and provides ~2" of lift. (1.5-2 inches of lift with 450 lbs)
