Traxxas TRX-4 Chevrolet K10 High Trail Edition

Stock is as the vehicle ships. Calculated is worked from the stock figures on this page rather than stored beside them, so the two cannot drift apart. Not published means it exists but no source we could find prints it.

How these numbers were settled

Two-speed, resolved.

• The High Trail TRX-4 owner's manual carries the same pair of formulas as the rest of the TRX-4 family (High Gear: '# Spur Gear Teeth / # Pinion Gear Teeth x 6.32 = Final Gear Ratio'; Low Gear: '... x 15.8') with taller 10-tooth pinion / 45-tooth spur stock gearing, giving chart values 28.44 (high) and 71.10 (low).
• The arithmetic matches exactly: 45/10 x 6.32 = 28.44 and 45/10 x 15.8 = 71.10.
• Traxxas's TRX-4 comparison chart independently lists this model's gearing as '10 / 45 (4.50:1)'.
• High gear is used as the final drive; low gear is 71.10:1.
• The 92056-4 product page publishes no gear-ratio row at all (only 'Gear Pitch: 32 pitch'), so there is no competing figure.
• Brushed Titan 550 21T reverse-rotation motor, so KV and the cell count are left blank.
• The tire diameter of 5.3 in (134.6 mm) is from the comparison chart's '2.2" x 5.3" Canyon Trail': 2.2 in is the wheel size the product page quotes, 5.3 in is the tire outside diameter.
• Portal axles.
• As on the TRX-4 Defender, Traxxas publishes no portal reduction for the 1/10 trucks; 2.5559 is derived as the value that reproduces both its printed 6.32 high and 15.8 low constants.
