Monroe Shocks & Struts Suspension Shock Absorber P/N:65410

Keep heavy loads planted and controlled with the Monroe Magnum Suspension Shock Absorber 65410, a gas-charged shock built for the punishing demands of class 6-8 trucks and buses. It's a direct-fit replacement for the 1970-1971 International CO190, the 1970-1971 International CO200, the 1971 International CO220 and the 2015-2024 Kalmar Ottawa T2 — see the Buyer's Guide tab for engine-level details. The catalog lists this shock for both front and rear positions.

• Nitrogen gas-charged design: the first gas-charged, large-bore shock for air spring and taper leaf suspensions, with a nitrogen charge for the fast response heavy-duty truck suspensions need.
• Consistent ride: all-weather fluid with special additives handles temperature extremes and helps reduce oil breakdown, while a larger 2-3/8-in. reserve tube holds more fluid (most applications).
• Exceptional handling: 10-stage valving tuned to each vehicle adjusts to road extremes, and a larger 1-3/4-in. bore provides more efficient damping control (most applications).
• Strong and durable: a shouldered bushing plus bonded bushing with sleeve guards against bushing walkout, with arc welds up to 360° for durability.

A robust hydraulic lock-out helps prevent over-extension of air bags and piston top-out to protect the seal assembly (most applications), while a PTFE-coated bearing and nitrocarburized piston rod reduce friction for longer service life (most applications). The nitrogen gas charge helps maintain tire-to-road contact by reducing aeration and shock fade for improved ride and handling. Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty. Replacing shocks as a matched pair per axle is recommended for balanced control.
