This kit comes with easy to follow directions and you can text or call if you have issues.. 

Fits right in the 50 series coolers,with the 51 series you will have to splice a few ends and ad some ends but it will come with the kit and its not hard at all..

These kits are a great upgrade to your 300 watt cooler,once upgraded it will have top speeds higher than any factory Cruzin Cooler made and will outrun a 500 watt with ease.Video below shows it..

This is what everyone with a 300 watt Cruzin Cooler must have 30% More run time,A noticable amount more torque and top speeds up to 20 mph depending on weight and road condition.Will help get up inclines and threw rough terrain..it also gives you a option to ad a brake light that works off the brake,just simply plug in any 24 volt 2 wire brake light right into the controller.

Tested and proven on my own Cruzin Cooler and many others for years...I have upgraded many 300&500 watt Coolers,its worth every penny!

This kit transfers your 24 volt cooler to a 36 volt,its a safe overvoltage kit and it works wonders on these Coolers and even more wonders on the 500 Watts..The controller allows the factory rpm to exceed past factory rpm but it keeps it still in the safe zone..

My kit includes everything you need and see above..it comes with..

1 new Trimax LED 36 volt throttle
with key and matching grip.

1 new 36 volt performance controller

1 new fan cooled 1.8amp 36 volt battery fast charger with trickle charge.

1 new matching battery--BATTERY CAN NOT BE SHIPPED OUT OF THE U.S.A- WE WILL REFUND $26 AND YOU CAN BUY IT ELSEWHERE BUT EBAY WONT ALLOW IT.

                                                    How hard is this to install?

It takes me about 15 minutes but I would look foward to about a hour of taking your time and doing it .

One of my customers wrote this..

" I bought an upgrade kit for my buddy's 300. it will walk away from my 500,I can't wait to get my kit installed in mine so I can keep up"

Another customer was going to buy a 1000 watt because he needed more run time and power..This is his email to me..

Update. After installing the 36 volt kit and finally making my tires real firm my cooler is super fast once it winds up. It is almost scary. It goes over 20 MPHs. At walking speed it seems to go all day too.
