This table covers the shocks and struts that damp wheel motion. Typical signs include a nose that keeps bouncing, cupped tires, or fluid weeping down the body. Replace shocks or struts in axle pairs and renew the mounts if they are torn or collapsed.

Buying Suspension Parts for a 2018 Freightliner M2

On this vehicle, the suspension system controls ride, tire contact and alignment through shocks, struts, control arms, bushings and links.

  • Match the engine first. Every suspension part here is engine-specific; each row shows which engine(s) it fits.
  • Read the notes on each row for position, trim and spec qualifiers before you order.
  • Where labor overlaps, replace shocks and struts in axle pairs, renew the sway-bar links with the struts, and get an alignment after any control-arm or tie-rod work.
  • Cross-reference the manufacturer part number against your old part or a service-manual listing.

Start with the largest groups on this page: Shock / Strut and Leaf Spring .

Frequently Asked Questions

How many suspension parts fit the 2018 Freightliner M2?

Our catalog currently lists 44 suspension parts for the 2018 Freightliner M2 across 3 subcategories and 6 brands, covering all 9 engine options (12.8L L6 DIESEL Turbocharged, 4.8L L4 DIESEL Turbocharged, 5.1L L4 DIESEL Turbocharged, 6.4L L6 DIESEL Turbocharged and more). Each part is matched to the engine(s) it fits.

Do suspension parts differ between 2018 Freightliner M2 engines?

Yes. Every suspension part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.

What are the signs of suspension problems on a 2018 Freightliner M2?

Common symptoms include clunks over speed bumps, wandering steering, cupped tire wear, or a nose that keeps bouncing after a dip. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.

What should I replace at the same time?

Where labor overlaps, replace shocks and struts in axle pairs, renew the sway-bar links with the struts, and get an alignment after any control-arm or tie-rod work.

What do the market flags (US, CA, MX) on each part mean?

They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2018 Freightliner M2 was originally sold in the US, the safest choice is a part marked for the US market.

How do I make sure a part fits my 2018 Freightliner M2?

First match the engine — each row shows which engine(s) the part fits. Then worn bushings often mimic bad shocks — inspect before buying, and remember loaded vs unloaded strut assemblies differ in labor by hours. The notes column carries position and trim qualifiers where they apply.
