6-Speed GTR Skyline gearbox

All Holinger gearboxes are built to order and entered with a default 12 week lead time. We can adjust this where possible to suit customer’s needs

However currently, in this strange time, we’re certainly not operating under usual conditions and have been completely inundated with orders in the last 6 months. So the reality is most orders are taking between 3-6 months to complete, depending on what it is, and where certain parts are in their production cycle.

• These transmissions are used with great success in cars with more than 1000hp in drag racing applications.
• All gears are removable from shafts with an extensive range of ratios available.
• The gear change is performed by using the standard Nissan gear lever and mechanism. The gear lever is pulled back for up changes and pushed forward for down changes.
• Clutch splines are normally 1 1/8" x 26, 24/48DP, 30 deg P.A., but can be ordered with standard Nissan splines.
