Primary Offset Kit

One of the best improvements to the latest models is the 6 speed gearbox. The Rocker® also has it.
But... After examining the 6 speed transmission we were shocked to find that the mainshaft incorporated 4 gearwheels, in one piece. A new longer gearshaft would have been too expensive to produce so a new kit was developed. Here’s the result:
13mm - Offset Kit "Hard Rock 13":
The 6 Speed Offset Pulley forms the heart of this kit, combined with laser cut aluminium parts, to allow for a 13mm primary offset. All without opening up the gearbox.
18mm - Offset Kit "Hard Rock 18":
Using our 18mm Primary Offset Kit we go even further, by using a slim 20mm drive belt. Again without opening up the gearbox. This kit even allows you to run a 300 on 10“ tire with minimal track offset.
