Motion Raceworks is in the business of solving problems.  When running a mechanical fuel pump on an LS engine or other engines where the crank pulley size is large and has a high HTD tooth count, it becomes difficult to locate the correct tooth count pulley for the fuel pump so as not to overspin and cause cavitation or underspin and limit performance. 

Motion solved this by creating our own HTD pulleys.  These pulleys are CNC machined and Made in the USA.   Featuring a spun on "fence" to insure the belt stays on, these pulleys are designed to be used with a standard 5/8" shaft.  We incorporated and use an 8mm HTD style tooth pattern.  Each pulley has 3 set screws.  

Anodized black and laser etched with the Motion Raceworks logo.  We also have a 50 tooth and 56 tooth pulley available in separate listings.
