Smooth out the ride in your heavy-duty rig with the Monroe Magnum Cab Suspension Shock Absorber 66159 — a gas-charged cab shock that isolates the cab from the frame for a more comfortable ride. It drops in as a direct-fit replacement on a wide range of Kenworth trucks, among them the 2008-2019 Kenworth T660, 1997-2011 Kenworth T2000 and 1985-2003 Kenworth K100E. See the "Vehicles it fits" section for the full list of applications.
- Velocity-sensitive valving: tuned for driver comfort on most applications, with 10-stage valving matched to the vehicle and a larger 1-3/8-in. bore for more consistent control.
- All-weather fluid: special additives help with temperature extremes and reduce oil breakdown, while the larger 2-in. reserve tube holds more fluid.
- Built for commercial duty: shouldered and bonded bushing with sleeve helps guard against bushing walkout, with arc welds up to 360° for durability.
- Longer service life: PTFE-coated bearing reduces friction between the rod and rod guide, and the nitrocarburized piston rod adds durability (most applications).
The nitrogen gas-charge helps maintain tire-to-road contact by reducing aeration and shock fade. Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.
