Steady a hardworking front suspension with the Monroe Magnum Front Suspension Shock Absorber 66412, a gas-charged shock built for the demands of high-mileage, severe-use Class 3-6 trucks and buses. It installs as a direct-fit front replacement for the 2008-2015 IC Corporation BE School Bus, 2013-2018 IC Corporation CE School Bus, 2013-2018 International 4300, and 2019-2024 International MV607 — see the Buyer's Guide tab for engine-level details.

  • Nitrogen gas-charge: maintains tire-to-road contact by reducing aeration and shock fade for improved ride and handling; helps reduce excessive vibration.
  • Consistent ride: all-weather fluid with special additives assists with extreme temperatures and helps reduce oil breakdown, while a 2-in. or 2-1/4-in. reserve tube holds more fluid (when required).
  • Exceptional handling: 10-stage valving tuned to the vehicle adjusts to road extremes, and a larger 1-3/8-in. bore provides more efficient damping control on most applications.
  • Strong and durable: shouldered bushing and bonded bushing with sleeve protect from bushing walkout, with arc welds up to 360° for durability.

A PTFE-coated bearing reduces friction between rod and rod guide, and a nitrocarburized piston rod supports a longer service life on most applications. Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.

Is this a front or rear shock absorber?

The 66412 is cataloged as a front suspension shock absorber for the listed Class 3-6 commercial applications.

Is the 66412 gas-charged?

Yes. It uses a nitrogen gas-charge that maintains tire-to-road contact by reducing aeration and shock fade, which helps improve ride and handling.

What are signs my front shock may need replacing?

Signs a worn shock may need replacing include excessive vibration, poor ride control, and reduced handling. Diagnose the cause before replacing, as other suspension parts can share these symptoms.

Should I replace shocks in pairs?

Replacing the left and right shocks on the same axle together as a matched pair is recommended for balanced ride control. This listing is for one shock; order two for a complete axle.
