Variator DR3 Kit GY6 150 Gokart

Regular price $149.95 Sale price $114.00

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
  • (6pcs each)-
  • -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!)
