Stable Power Transfer with a 90 Tooth Spur

The Yokomo SG-A4890A 90T Spur Gear is targeted at 1/10 scale model drivers who need dependable and consistent drivetrain behaviour. It combines accurate tooth form with a build suited to regular track use.

How the 90T Improves Driveability

The 90-tooth arrangement smooths torque delivery and helps with speed control through corners. Built to fit DP48 pitch systems it integrates with a wide range of 1/10 chassis so you can upgrade without a complex setup change.

Simple Installation and Checks

Fitting the SG-A4890A is straightforward on standard 1/10 gearboxes; fit the spur, adjust pinion mesh carefully and perform short test runs. Inspect the gear after hard impacts and keep it clean to preserve tooth integrity.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Which 1/10 cars will accept this spur?

Any 1/10 chassis using DP48 pitch and a compatible spur mount should accept the SG-A4890A, but always confirm bore and mount type before purchase.

What signs indicate the spur needs replacing?

Look for rounded or chipped teeth, rough mesh, or excessive backlash; these signs point to replacement to avoid further drivetrain damage.

Is lubrication necessary on the spur?

A light application of gear-safe lubricant on mating surfaces can help reduce wear, but avoid heavy grease that traps dirt.

Will using a 90T change my top speed?

Changing tooth counts alters the overall gear ratio; a larger spur can lower top speed but improve acceleration smoothness, depending on pinion choice.

Any fitment tips for quieter running?

Ensure correct pinion mesh, use well-maintained bearings, and avoid excess lubricant on the gear faces to keep noise down.
