Hardened Tool Steel Strength for 420 Chain Setups

If you are running a 420 chain conversion on your build, this

Warp 9 420 Jackshaft Sprocket

is the upgrade you want. Precision machined from hardened tool steel and finished with a black oxide coating, it is built to handle higher torque loads, aggressive riding, and long-term wear without premature failure.

We have seen stock sprockets wear quickly once power levels increase. This is a simple drivetrain upgrade that adds real durability and peace of mind.

Construction and Materials

Hardened Tool Steel for maximum strength and wear resistance

Black oxide coating for corrosion protection

Designed specifically for 420 chain setups

Precision machined for accurate fit and smooth drivetrain operation

Tooth Count Options

14 Tooth

– Stock replacement size for 420 setups. Maintains factory-style torque and acceleration feel.

15 Tooth

– Lowers RPM at cruising speed for smoother riding and potential top speed gains. Slight reduction in torque compared to 14T.

Important Fitment Note

This sprocket does NOT fit bikes running a 428 chain.

It is not compatible with E-Ride Pro SR or E-Ride Pro SS 3.0 models in their stock 428 chain configuration. Those bikes require a 428 specific sprocket unless converted to a full 420 chain system.

Fitment

E-Ride Pro models with to 420 chain

At REV Rides, we always recommend matching sprockets exactly to your chain pitch. Running the correct 420 sprocket with a 420 chain ensures proper engagement, smoother power delivery, and longer drivetrain life.

Best For

Riders completing a 420 chain conversion

High power builds looking for stronger drivetrain components

Trail and track riders who want long-term durability
