PPG Helical Synchro gear set for Evo 4-9 (1ST-4TH)

Ratios 2.846 / 1.938 / 1.389 / 1.000

This is what the market has been asking for for a long time now. A sturdy gear set that can hold serious power in the 800Nm range, while operating like a normal gearbox. These do make some additional noise, but are nothing like a straight cut dog box. The set comes with a modified 3-4 hub in order to run the three piece synchro on 4th gear.

We recommend building these with a bearing and seal kit, billet diff tube, and carbon synchro rings.

You can also add in billet selector forks – 1-2, 3-4 and 5-R are all available here.

These sets are compatible with all OEM final drives, and factory 5th gear works, too.
