Description
These are the Kyosho Inferno ST-RR EVO straight cut 43 tooth ring bevel gears and have been revised since the older style spiral cut gears. These are now made of the strongest material; available and are more durable than any previous ring and pinion set for the Kyosho ST-RR. Track tested and perfected! These are also much easier to shim than the old gears. Use these in the "D" version KYOIF112D bulkheads and you will have the most bullet proof setup yet!
