Features:
- PRECISE HANDLING AND PERFORMANCE -- Deflective Disc Valving features digressive, linear or progressive tuning based on application requirements for precision handling and performance on- and off-road
- STRONG AND DURABLE -- Features a 14mm hardened chrome piston rod to resist scuffs & corrosion, double-welded loops at stress areas, double strength closure method and hot form reserve tube
- HANDLES EXTREME TEMPERATURE CHANGES -- Large 2-in. monotube body filled with all-weather fluid allows for cooler operation, increased vehicle control and ability to withstand internal temperatures of -40 to 248 degF
- REDUCES FADE -- Full-floating dividing piston and high-pressure nitrogen gas maintains constant pressure against the hydraulic oil, reducing aeration and shock fade
- SMOOTH PERFORMANCE -- Internal rebound bumper and shouldered rubber bushings help reduce noise, vibration and ride harshness while the PTFE-banded piston enhances responsiveness to changing road conditions for an overall smoother ride
- THE RIGHT FIT -- Designed to fit right out of the box, application-specific mounting installs easily with no need for installing sleeves or extra hardware
- KEEPS DIRT AND DEBRIS OUT -- Sealing system with integrated dirt wiper helps keep moisture, dirt and debris from being ingested into the shock and contaminating the oil and destroying the internal seal
- BUILT TO LAST -- Large 46mm fluon-banded piston for consistent sealing between the piston and monotube for precise control, ride and handling; for extra protection, purchase shock boot RS1952 or RS1961
- BOLD APPEARANCE -- Black satin finish with distinctive Rancho red logo for an eye-catching look that stands out
- BUY WITH CONFIDENCE -- Comes with Rancho's Limited Lifetime Warranty
