Holinger PG81 Gearset Features:

• Ratios optimized for fast road, track day, and racing use.

• Reinforced gears are made from superior VAR nickel alloy with strength-focused tooth profiles.

• New gears are direct replacements and require no gearbox modifications.

• Synchro dog-rings are splined to the gear - this prevents ring-detachment failure that has been

known to occur in standard GT4 gearboxes (see close-up image below).

• All gear teeth are profile-ground after heat treatment, ensuring the most accurate engagement

and tooth finish - resulting in quiet, more efficient running.
