Description

Keep your class 3-6 truck or bus riding steady with the Monroe Magnum Front Suspension Shock Absorber 66675, a gas-charged front shock built for the demands of high-mileage, severe-use commercial vehicles. It installs at the front position on many vehicles, among them the 1992-2002 Chevrolet W4500 Tiltmaster, 1992-1999 GMC W4500 Forward and 1986-1996 GMC W7500 Forward — see the "Vehicles it fits" section for the full list and engine-level fitment. Replace worn-out units to help reduce excessive vibration and support controlled damping.

Nitrogen gas-charge: maintains tire-to-road contact by reducing aeration and shock fade for improved ride and handling.
10-stage valving: tuned to the vehicle and paired with a larger 1-3/8-in. bore for more efficient damping control on most applications.
All-weather fluid: contains special additives for extreme temperatures and to help reduce oil breakdown; the 2-in. or 2-1/4-in. reserve tube holds more fluid.
Built to last: PTFE-coated bearing reduces friction between rod and rod guide and a nitrocarburized piston rod adds durability, while shouldered and bonded bushings protect against bushing walkout (most applications).

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

Frequently Asked Questions

Which trucks does the Monroe Magnum 66675 fit?

It fits many class 3-6 trucks and buses, among them the 1992-2002 Chevrolet W4500 Tiltmaster, 1992-1999 GMC W4500 Forward and 1986-1996 GMC W7500 Forward. See the "Vehicles it fits" section for the full list.

Is this a front or rear shock absorber?

The 66675 is cataloged as a front suspension shock absorber for the listed applications.

Why is the Magnum shock gas-charged?

The nitrogen gas-charge helps maintain tire-to-road contact by reducing aeration and shock fade, which supports improved ride and handling on demanding commercial vehicles.

What are signs my shock absorber may need replacing?

Excessive vibration, a rougher or bouncy ride, reduced damping control, or fluid leakage can indicate a worn shock. Diagnose the cause before replacing, as other components can produce similar symptoms.

Should I replace shocks in pairs?

This listing is for one shock. Replacing both sides on the same axle together is recommended for balanced, even damping, though it is not strictly required.
