- GET THE RIGHT PART -- Before purchasing, research to ensure that the part will fit your vehicle; enter all vehicle information (year, make, model, engine and trim) for compatibility and check qualifier notes
- FOR HARDWORKING COMMERCIAL VEHICLES -- Designed to handle the demands of high mileage and severe use class 3-6 trucks and buses
- CONSISTENT RIDE -- All-weather fluid contains special additives to assist with extreme temperatures and help reduce oil breakdown while 2-in. or 2-1/4-in. reserve tube holds more fluid to improve performance (when required)
- EXCEPTIONAL HANDLING -- 10-Stage valving, tuned specifically to each vehicle, adjusts to road extremes while the larger 1-3/8-in. bore provides more efficient damping control to provide consistency and a smooth ride (most applications)
- STRONG AND DURABLE -- Shouldered bushing and bonded bushing with sleeve protects from bushing walkout for improved quality; arc welds up to 360 for durability
- BUILT TO LAST -- Robust hydraulic lock-out prevents over extension of air bags, top-out of the piston and averts damage to seal assembly (on most applications)
- LONGER SERVICE LIFE -- Bearing with PTFE coating reduces friction between rod and rod guide combined with nitrocarburized piston rod provides durability and longer service life (most applications)
- REDUCED NOISE, VIBRATION AND HARSHNESS -- Delivers exceptional control and isolates impact-related noise, vibration, and harshness under most driving conditions
