We have the solution so your hopper will keep feeding paint like mad without breaking. Coupled with our O.D. overdrive pulley is our new durable delrin drive cone.
NDZ overdrive (O.D.) pulley. Features dual grooves for 2 speed choices. This basically almost doubles the speed of your hopper. The deeper groove is much faster than stock, while the other groove is even faster. Simply press on by hand over the brass Halo motor pulley.
Stock gear ratio is a 6.2:1 while our first ratio is about 4:1 and the faster groove is a whopping 3.7:1
