Product Benefits:
- Rubber shielded bearings add sealed protection against dirt, dust, and debris for off-road, outdoor, bashing, short-course, gravel, grass, parking-lot dust, and debris-prone use.
- 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.
Search-Friendly Notes: Compatible ARRMA senton 3s blx screw kit and bearing kit fitment data for J-M SUPPLIES RC buyers searching ARRMA parts, ARRMA screws, ARRMA bearings, and RCScrewZ model-specific hardware.
