  • A strong choice when durability and reduced contamination exposure matter more than the absolute lowest rolling drag.

Reason to Purchase: Choose rubber shielded bearings for added sealed protection against dirt, dust, and debris, especially when running this Losi or TLR platform outdoors, off-road, or in mixed-surface conditions where metal shielded low-drag bearings may be exposed to contamination.

Fitment Note: Confirm your vehicle model and OEM number before ordering. This kit is configured for the listed Losi/TLR platform and is not a universal hardware or bearing assortment.

Search-Friendly Notes: Useful for Losi parts, TLR parts, losi lmt 3s screw kit, losi lmt 3s bearing kit, RC rebuild, RC maintenance, and model-specific upgrades.
