What vehicles does the Monroe Magnum 66450 fit?
It's a rear suspension shock absorber for the 2010-2018 Freightliner Sprinter 2500 and 2010-2018 Mercedes-Benz Sprinter 2500. Check the Buyer's Guide tab to confirm fitment for your vehicle.
Is this a front or rear shock absorber?
It is a rear unit — the 66450 is cataloged as a rear suspension shock absorber.
How many shocks do I need?
This listing is for one shock, sold individually. Shocks work as a pair per axle, so replacing both rear sides together as a matched set is recommended for balanced, even ride control.
What does the gas-charged design do?
The nitrogen gas-charge helps maintain tire-to-road contact by reducing aeration and shock fade, which supports improved ride and handling.
What are signs my rear shocks may need replacing?
Excessive vibration, bouncing, or reduced ride control can indicate worn shocks. Diagnose the cause first; if worn rear shocks are the issue, these Magnum units replace them.
