Pulley Systems

Machined from 6061-T6 Aluminum w/genuine HTD® pulley stock to increase belt life & run more efficient than stock pulleys. 

Developed to meet the needs of the most strenuous riders with pressed in bearings. Customize & tune your Boosted Pulleys, Evolve Skateboard Pulleys & Lacroix Board Pulleys to your riding & wheels! 

Developed To Be The Best

We start by using genuine HTD® curvilinear tooth profiles in our pulley systems. In addition to the increased durability that 6061-T6 Aluminum offers compared to plastic pulleys, they also increase belt life and run more efficient & quieter.


We then machine our Pulley Systems to 1/1000th of an inch to press in our bearings for a perfect fit. You'll see other ESK8 brands use Loctite or glue to seat their bearings, we give you a perfect bearing fit and don't cut any corners! 

Interchangeable System

 Start by choosing your hub... Abec, Kegel or both! 

Then choose different ratios for your Boosted Board Pulley or Evolve Skateboard Pulley to tune in your riding style or get those big wheels rolling at the correct speed.


Can't decide what ratio's for you? All our systems are interchangeable so you can swap between ratios and hubs based on your wheel combos! 

Cutting Edge Design

With our new two-piece metal pulley design we bring new levels of adaptability and riding style tuning to your board with top of the line materials. 


 At Skate Kastle our motto has always been to provide the best products for your board. Upgrade your Boosted Board Pulley, Evolve Skateboard Pulley or Lacroix Boards Pulley to the next level with these Aluminum Pulley Systems!
