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.
