Durable 48P 90T Spur Gear from 3Racing

The 3Racing 48 Pitch Spur Gear 90T, model number 3RAC-SG4890, provides a durable gear option for hobbyists wanting reliable power transfer. Its 90 tooth layout helps deliver steady torque and reduces shock loading in rough conditions.

Why This Gear Works Well

Tooth Count: 90T to lower tooth stress and smooth output
Pitch: 48P to match common pinions in many RC fleets
Material: Built from tough materials to resist impact and wear
Application: Useful for both upgrades and routine part replacement on diverse models

Do I need to change my pinion to use this spur?

Not if your current pinion is 48P. Keep tooth counts and pitch matched and then set the mesh with a feeler or shim method.

How do I check gear mesh correctly?

Fit the spur and pinion, hold the gear tight, rotate to seat teeth, and leave a small clearance about the thickness of a business card between face and root.

Will the 90T affect top speed significantly?

Tooth count affects final ratio. Swapping to 90T will alter gearing compared with smaller spurs, so pick the combination to match your desired acceleration and top speed.
