✓Product Features: FleetLine shocks are designed as a direct replacement for commercial OE shocks, so they’re built to match and/or exceed OE specs and quality standards. They also feature a valving rate that compensates for initial truck suspension softening, providing performance that specifically matches the original
✓Installation & Durability: Rugged, Self-Compensating Piston Seal for consistent damping to maximize shock life/High-Performance Chromed Piston Rod that provides superior corrosion protection/360 degree arc welded end mounts protect against end mount breakage/ANTI-CORROSIVE END MOUNTS (Most Applications) that prevent rust and bolt seizure, and eliminates torching to remove a shock which improves your uptime/Hydraulic rebound stop (Where applicable) prevents impact damage to the shock and Air Springs
