  • They help reduce contamination exposure when protection matters more than the lowest possible rolling drag.

Reason to Purchase: Choose rubber shielded bearings when sealed protection against dirt, dust, and debris matters more than the lowest possible rolling drag, especially for ARRMA bashing, outdoor running, and dirty RC conditions.

Fitment Note: Confirm your ARRMA OEM/model number against the codes above before ordering. This kit is intended for the listed ARRMA model family only.
