Patented Technology

KAPS Transmissions dog kits contain the latest in shifting advancements. Our unique patented system for dog engagement replaces the 50 year old methods employed by other manufacturers and has proved successful with the results from our customers. For homologated classes, the shift lever must remain, but the distance the shift lever must move to engage the gear can be shortened. KAPS Transmissions’ design enables the driver shorter gear shifts, thereby enabling quicker stage times. According to our measurements the time saving between the synchronous and our dog-box transmission is approximately 0.2 second per kilometre, which means 40 seconds to the credit per 200 km of speed tests.

The geometry of the tooth curve is designed as special circle system which provides lower rolling-resistance force and higher strength – this means lower power losses and decreased noise.


Available for £5,950+VAT, the Evo X Dog Box Gear Kit is the smoothest and quickest shifting Evo X dog kit on the market today.
