Has anyone replaced the "Factory Installed" Monroe (555001) Shocks with another brand/model.

Recommended Posts

To the Forum,

Has anyone changed to different shock than the factory installed Monroe 555001. 

If so, Brand, Model/part number.

Did you go to a firmer or softer shock.  Have you changed back or tried another shock?

  • 2-inch (50.8 mm) or 2-3/8-inch (60.3 mm) reserve tube: The 2" (555xx Series) or 2-3/8' (557xx Series) reserve tube holds more fluid or more consistent performance - when required.
  • 1-3/8-inch (35 mm) or 1-3/4-inch (44.6 mm) bore: The 1-3/8' (555xx Series) or 1-3/4" (557xx Series) bore is larger than most shocks to provide more efficient and consistent control - when required.

  • The title was changed to Has anyone replaced the "Factory Installed" Monroe (555001) Shocks with another brand/model.

Have wondered and considered the same myself just too busy with other things to dive in. However it might be worth checking with Shock Surplus a mail order company that specializes in after market high performance shocks. There are most likely other mail order companies doing this but these guys seem to be informed.

We replaced (what is believed to be the original factory yellow Monroe 555001's) our shocks with new "black" 555001's last April - if originals; that would make them 6+ years old (we bought ours from the original owner - who didn't keep track of the mileage).


As it turned out, 3 of the 4 shocks were bad...  It's easy to test them - pick a side, and jack it up.  Place a safety jack stand in place.  Remove the lower nut, compress the shock and remove from the keeper.  Release compression, a healthy shock will fully extend after releasing.  3 of ours would not extend after compressing.  My sense is these shocks are good for only 3 or 4 years, obviously depending on mileage.


It would be nice to learn if another manufacturer (Bilstein, perhaps?) has an upgrade replacement....

Cheers and "Ravel-On!"
