These are apparently the part numbers to "upgrade" your stock transmission to the Highlifter specs.

I installed this gear set in my 2014 XP4 1000, and got ZERO gear reduction.
In fact I now have a 2 mph HIGHER TOP SPEED than I did with the stock gears. (GPS TESTED)

Turner Cycle told me that their 32" gear reduction was the same ratio as the Highlifter. They also told me that their 32" gear reduction is a lower gear than the xp4 1000.

Something does not add up here.
