L-Series, Heavy Duty Synchro gear set is based on the latest 10th Generation Honda Civic Si 1.5l Turbo.

The L-Series Synchro Gearset has been designed from scratch with the intent to not only make a strong high performance gearset, but also address some of the known issues with the OEM gearbox

The PPG L-Series gear set supplies a straight cut 1st gear with helical gears, 2nd, 3rd & 4th. The 1st gear synchro design has been refined to operate smoothly which enables the elimination of premature wear. A characteristic seen in the OEM gearbox.

The PPG L-Series gear ratios have been optimised to maximise vehicle performance. Optimised gear ratios allow for minimal boost and RPM drop per gear
