Upgrade bearings for Mini Spyder MT performance

Sold as a set of four 8x12x3.5 ball bearings, these units are intended as direct replacements on the Serpent Mini Spyder MT platform. They are designed to reduce rotational friction in hubs, diffs, and other drivetrain positions where 8x12x3.5 bearings are specified.

Fitment is aimed at the Mini Spyder MT chassis; use these bearings wherever the original component uses the 8x12x3.5 size. The four pcs included are suitable for replacing worn bearings encountered during regular tuning or after abrasive off-road conditions.

Tuning and installation tips: bearings drop in to hubs and diff carriers that accept 8x12x3.5 sizes. Clean mounting bores, confirm bearings seat fully and spin freely, and swap bearings in matched groups to preserve drivetrain harmony. Light lubrication and routine checks will help maintain peak performance.

Will lower friction bearings change handling?

Smoother bearings can reduce drivetrain drag, which may give crisper throttle response and slightly different feel. For best results, keep all rotating parts balanced and checked after installation.

Should I use oil or grease with these bearings?

Use a light bearing oil or thin lubricant formulated for RC bearings to minimize drag while protecting against grit. Avoid heavy greases unless the application calls for extra sealing against contamination.

Any tips to keep drivetrain balanced after fitment?

Replace bearings in matched positions, check axle and hub play, and verify smooth rotation by hand before full testing. This helps prevent vibration and uneven load on gears and diffs.
