KNM has improved our original DR2 Variator and now, we're making the DR3 right here in the USA! If you liked our DR2, you're going to LOVE our DR3! No more trading your top end for low end torque like you do in any other Variator, in fact testing showed some increase in top end speed too!! NO HYPE, NO FLUFF, NO other Variator can touch our DR3 in your Gokart!
With a Larger slide face and deeper/steeper Slide ramps that are specifically designed to accentuate the travel of your Polygon weights, we have greatly improved take off and top end!
It's the most tunable and user friendly variator on the market AND, we knock the snot out of the DRPulley variators performance, by quite a bit!
The DR3 kit comes with everything you need:
-115mm Fixed outer fan with 19 splines,
-KNM Race modified variator,
-Backing plate with durable nylon guides
-Center Boss pin and
-NEW- $90 Free) 3 sets of quality Slider weights, instead of Rollers
-10 gram sliders,
-12 gram sliders
-14 gram sliders
Use one of the included 6 slider weight sets or Mix & Match between 2 sets to tune your low end, change your shifting speed and your Top end! Our Race modified ramps are designed to get more out of your Polygon weights than any other variator. We accentuate the positive!
There's nothing else that even comes close to our DR3 and it just slides on and bolts right up in just a couple minutes! (1 fan nut, it's that easy and nothing else needs to change!)
This kit fits Most GY6 150cc Gokarts and ATV's as well as MOST other GY6 125/150cc Scooters from China.
