MODEL-SPECIFIC HELP

Questions About This RC Model?

Answers for the verified kit options available for Losi LMT 3S 1/8 Electric 4WD Monster Truck (LOS04021). Confirm the OEM/model number before ordering.

How do I confirm these kits fit Losi LMT 3S 1/8 Electric 4WD Monster Truck (LOS04021)?
Confirm the OEM/model number LOS04021 on your RC vehicle, box, manual, or parts diagram. This Model Collection lists the verified RCScrewZ Stainless Screw Kit, Rubber-Sealed Bearing Kit, and Metal-Shielded Bearing Kit assigned to Losi LMT 3S 1/8 Electric 4WD Monster Truck (LOS04021). A similar model name, body, scale, or chassis, is not enough to confirm fitment.
What is included—and not included—in the Stainless Screw Kit?
The model-specific RCScrewZ Stainless Screw Kit includes the stainless screws selected for common assembly locations on Losi LMT 3S 1/8 Electric 4WD Monster Truck (LOS04021), plus matching nuts and washers where required, extra common sizes, Bondhus short-arm hex wrenches, and a reusable storage case. Exact counts and sizes vary by kit. It does not include electronics, shocks, motors, engines, bearings, or molded plastic parts.
What is included in the RCScrewZ Bearing Kits?
Each model-specific bearing kit contains the bearing sizes assigned to Losi LMT 3S 1/8 Electric 4WD Monster Truck (LOS04021), along with spare bearings and a reusable storage case. Depending on the model, a kit may include standard, flanged, one-way, or thrust bearings.
Should I choose Rubber-Sealed or Metal-Shielded Bearings?
Choose Rubber-Sealed bearings for off-road use, dust, dirt, sand, mud, and lower-maintenance protection. Choose Metal-Shielded bearings for cleaner on-road or prepared surfaces when lower drag is the priority. Both kits are model-specific for Losi LMT 3S 1/8 Electric 4WD Monster Truck (LOS04021); the difference is the shield type and intended operating environment.
