HKS 6 Speed H-Pattern Dog Box

HKS 6 speed H-Pattern dog box, with transfer case.

It was previously in an R32 GTR. Rated to 1000hp + these box's allow faster more positive shifts with out any issues of syncro's failing. Larger gears and stronger material ensure flawless use.

A dog engagement system offers more power transfer capacity compared to synchro systems giving added strength and reliability and with correct driver operation, fast shifting is possible.

H pattern shifting is popular due to the strong natural feeling of each gear change. The Shift pattern has been designed to allow the most used gears on the circuit (2nd and 3rd) to have a simple forwards/backward motion to shift between them (different on some models) Each shift pattern is designed to suit the characteristics of the each vehicle.

This box can also be modified using a cam barrel to become sequential. Using a barrel cam which converts the I shift pattern to that of an H pattern has allowed HKS to create a sequential transmission based on a reliable manual transmission base. Quick and accurate gear changes are now possible with particular attention paid to the weight and stroke of each gear change to give a genuine race car feel to your car.

This racing gearbox's cost over 20k to buy new and are hard to find. Any proper race car will have some kind of an h-pattern dog box.

Will suit r32, r33, r34, can be used in Silva's, etc. It can be modify to fit other Nissan's, Toyota's, and other performance cars.
