Smooth out a high-mileage ride and help keep the rear wheels planted with the Monroe Magnum 66450 Rear Suspension Shock Absorber. Built for hardworking commercial vans, it installs as a direct-fit replacement for the 2010-2018 Freightliner Sprinter 2500 and 2010-2018 Mercedes-Benz Sprinter 2500 — see the Buyer's Guide tab for full engine details.

  • Gas-charged: A nitrogen gas-charge helps maintain tire-to-road contact by reducing aeration and shock fade for improved ride and handling.
  • 10-Stage valving: Tuned to each vehicle to adjust to road extremes, with a larger 1-3/8-in. bore for more efficient damping control (most applications).
  • All-weather fluid: Special additives assist with extreme temperatures and help reduce oil breakdown, while a 2-in. or 2-1/4-in. reserve tube holds more fluid (when required).
  • Strong and durable: A shouldered and bonded bushing with sleeve protects from bushing walkout, and arc welds up to 360° add durability. A PTFE-coated bearing reduces friction between the rod and rod guide alongside a nitrocarburized piston rod (most applications).

Designed to handle the demands of high-mileage, severe-use class 3-6 vehicles. Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty. Sold individually; for balanced control, replace both rear shocks together as a matched pair.

Frequently Asked Questions

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.
