Hard Chromed Piston Rod The piston rod features a super finished hard chrome-plated surface with a maximum peak-to-valley measurement of .0002mm.
1-Pc Alloy Rod Guide & Seal System The lightweight one piece rod guide is made from a unique aluminum alloy that maintains a nearly friction-free surface for longer life. The superior end seal design keeps dirt out of the working cylinder and prevents leakage; even under severe pressures of up to 2150 psi.
Rising Rate Self-Adjusting Digressive Working Piston Unique piston design provides completely independent valving between compression and rebound cycles. Patented digressive valving allows maximum vehicle body motion control while reducing impact harshness.
Patented Nitrogen Chamber & 'Floating' Dividing Piston Nitrogen gas maintains constant pressure against the low-mass 'floating' dividing piston and the column of hydraulic oil; virtually eliminating the possibility of oil foaming and performance loss.
