Keep heavy-duty miles under control with the Monroe Magnum Suspension Shock Absorber 65175, a front, gas-charged, large-bore shock built for class 6-8 trucks and buses. It drops in as a direct-fit replacement for the 2010-2022 Kenworth T270, 2013-2024 Kenworth T680, 2008-2018 Peterbilt 325, and 2014-2024 Peterbilt 567 — one of 17 applications, so see the Buyer's Guide tab for the full list. Monroe describes the Magnum as the first gas-charged, large-bore shock for air spring and taper leaf suspensions, using a nitrogen gas charge for the fast response heavy-duty suspensions demand.
- Exceptional handling: 10-stage valving tuned to each vehicle adjusts to road extremes, and on most applications the larger 1-3/4-in. bore provides more efficient damping control for a smooth, consistent ride.
- Consistent ride: all-weather fluid contains additives to help handle extreme temperatures and reduce oil breakdown, while a larger 2-3/8-in. reserve tube holds more fluid (most applications).
- Strong and durable: shouldered bushing and bonded bushing with sleeve help protect from bushing walkout, with arc welds up to 360° for durability.
- 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 is designed to help maintain tire-to-road contact by reducing aeration and shock fade. Robust hydraulic lock-out helps prevent over-extension of air bags and piston top-out on most applications. Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.

Frequently Asked Questions
What is the Monroe Magnum 65175?
It's a front, nitrogen gas-charged, large-bore Suspension Shock Absorber built for class 6-8 commercial trucks and buses. Monroe calls it the first gas-charged, large-bore shock for air spring and taper leaf suspensions.
Which vehicles does it fit?
It's a direct-fit replacement across 17 applications, including Kenworth T270, T280, T370, T680, T880 and Peterbilt 325, 337, 348, 567 and 579. Check the Buyer's Guide tab to confirm the exact year and model for your truck.
Is this a front or rear shock?
The catalog lists it as a front position Suspension Shock Absorber.
What does the 10-stage valving do?
The 10-stage valving is tuned to each vehicle and adjusts to road extremes, and on most applications the larger 1-3/4-in. bore provides more efficient damping control for a smooth, consistent ride.
What are signs my shock may need replacing?
Common signs include excessive bouncing, poor ride control, uneven tire wear, or fluid leakage. Diagnose the cause first, since these symptoms can have other sources; if a worn shock is the cause, this replaces it.
