- 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 with special additives handles extreme temperatures and reduces oil breakdown; 2-in. or 2-1/4-in. reserve tube holds more fluid for improved performance (when required).
- Exceptional Handling: 10-Stage valving tuned per vehicle adjusts to road extremes; larger 1-3/8-in. bore provides more efficient damping and a smoother ride (most applications).
- Strong and Durable: Shouldered and bonded bushing with sleeve protects from bushing walkout; arc welds up to 360° for durability.
- Built to Last: Hydraulic lock-out prevents over-extension of air bags and protects the seal assembly (most applications).
- Longer Service Life: PTFE-coated bearing and nitrocarburized piston rod provide durability and extended service life (most applications).
- Reduced NVH: Exceptional control isolating impact-related noise, vibration, and harshness under most driving conditions.
- Improves Performance: Nitrogen gas-charge maintains tire-to-road contact by reducing aeration and shock fade.
