Superflex Deaver Q80 Leafs
Deaver's Progressive Series springs are high quality 9-leaf units and fabricated by Deaver 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.
Other design features include diamond cut inner leaf ends minimizing shear points, anti-friction pads inserted between the leafs for a smoother ride and quiet operation, full military-wrapped spring eyes for superior durability.
They are 2.5 inches wide and the leaf springs measure 58 inches from eye to eye. They are not left/right specific.
Combined with properly valved high performance shock absorbers, the ride is enhanced beyond belief.
Springs come with bushings |
