Manufacturer Upgrade Advice

According to FTX, if upgrading your Tracer’s drivetrain to feature machined metal gearing, a machined metal spur gear, or a heavy-duty centre driveshaft, all of the following parts are required to complete the upgrade:

• 1 ×FTX9776– Centre driveshaft(replaces FTX9721)

• 1 ×FTX9777– Metal spur gear

• 2 ×FTX9778– Metal differential gear sets

Each FTX9778 contains gears for one differential, so two sets are needed for a full front and rear differential upgrade.
Metal differential gears replace FTX9726, or FTX9717 if upgrading from pre-built differentials with bearings.
