Shock Absorber for 2010-2022 Peterbilt 348 & More - Monroe 65401

Keep heavy-duty suspensions damped and under control with the Monroe Magnum Suspension Shock Absorber 65401 — a gas-charged, large-bore shock designed for the demands of high-mileage, severe-use class 6-8 trucks and buses. It installs in the front or rear position and is the first gas-charged, large-bore shock built for air spring and taper leaf suspensions, using a nitrogen gas charge for the fast response heavy-duty truck suspensions need. It fits the 1994-1997 Ford F-700, F-800 and FT900, plus a wide range of Peterbilt models including the 220, 330, 357, 379 and 389 — see the "Vehicles it fits" section for the full list of applications and years.

• Exceptional handling: 10-stage valving tuned to each vehicle adjusts to road extremes, while the larger 1-3/4-in. bore provides more efficient damping control for a smooth ride (most applications).
• Consistent ride: all-weather fluid additives help handle temperature extremes and reduce oil breakdown, and a larger 2-3/8-in. reserve tube holds more fluid (most applications).
• Strong and durable: shouldered and bonded bushing with sleeve helps protect against bushing walkout, with arc welds up to 360°.
• Longer service life: a PTFE-coated bearing reduces friction between rod and rod guide, and a nitrocarburized piston rod adds durability (most applications).

Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.
