GT4 Reinforced 3rd Gear
TECHNICAL DESCRIPTION
A replacement to the weak and poorly designed factory 3rd gear in the GT4. Synchro dog-rings are splined to the gear - this prevents the ring-detachment failure that has been known to occur in standard GT4 gearboxes (see close-up image below). Holinger delivers again!
We've been searching for a quality 3rd gear replacement for the GT4 and found it in Holinger, the manufacturer of gears for Porsche Racing!
