MODEL-SPECIFIC HELP

Questions About This RC Model?

Answers for the verified kit options available for Kyosho Inferno MP777 SP1 1/8 Nitro 4WD Buggy (31778). Confirm the OEM/model number before ordering.

How do I confirm these kits fit Kyosho Inferno MP777 SP1 1/8 Nitro 4WD Buggy (31778)?
Confirm the OEM/model number 31778 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 Kyosho Inferno MP777 SP1 1/8 Nitro 4WD Buggy (31778). 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 Kyosho Inferno MP777 SP1 1/8 Nitro 4WD Buggy (31778), 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 Kyosho Inferno MP777 SP1 1/8 Nitro 4WD Buggy (31778), 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 Kyosho Inferno MP777 SP1 1/8 Nitro 4WD Buggy (31778); the difference is the shield type and intended operating environment.
