Keep a hardworking truck controlled over high-mileage, severe-duty roads with the Monroe Magnum Rear Suspension Shock Absorber 65172. It installs as a direct-fit rear replacement on many vehicles, among them the 2003-2009 Chevrolet C4500 Kodiak, 2003-2009 Chevrolet C5500 Kodiak and 2003-2009 GMC C4500 Topkick. See the "Vehicles it fits" section for the full list.
The Magnum is a gas-charged, large-bore shock built for class 6-8 vehicles running air spring and taper leaf suspensions, using a nitrogen gas charge that delivers the fast response heavy-duty suspensions demand.
- Consistent ride: all-weather fluid with special additives helps with extreme temperatures and helps reduce oil breakdown, with a larger 2-3/8-in. reserve tube holding more fluid on most applications.
- Exceptional handling: 10-stage valving tuned to each vehicle and a larger 1-3/4-in. bore provide more efficient damping control on most applications.
- Strong and durable: shouldered bushing and bonded bushing with sleeve help protect from bushing walkout, with arc welds up to 360°.
- Longer service life: a PTFE-coated bearing reduces friction between the rod and rod guide, combined with a nitrocarburized piston rod (most applications).
The nitrogen gas-charge helps maintain tire-to-road contact by reducing aeration and shock fade, and the shock isolates impact-related noise, vibration and harshness under most driving conditions. Backed by Monroe's 90-Day Risk Free Ride Offer and Limited Commercial Warranty.
