These gears are the MOST OD you can get at the ring and pinion
These % are changing the front gear and leaving the rear alone with stock 8-30
8/24=3-1 22%OD
8/27=3.375-1 11%OD
The UD gearset below is calculated using the stock 8/30 gearset in front
8/33=4.125 10%UD
If your transmission has OD/UD built in, that will affect the overall OD/UD of the driveline. This also assumes you have the stock portal gears, the AR45 Portal gears fit these for endless gearing adjustments.
Add the percentages to get the OD you want.
These gears come with the spool, its similar to the older version BOOM RACING Triangle locking spool before the now standard 6-bolt design came out. They are a hardened steel and will fit any Axial or Vanquish axle that uses the AXIAL size AR45 gearset.
