Our DHD Heavy Duty Billet Spool is your ONLY choice for you Duramax Diesel or Dodge Cummins Diesel. This is the absolutely best, most heavy duty spool in the aftermarket and is manufactured from start to finish right here in the MotorCity.
This is the same 38 spline spool that comes in our axle & spool kit. Our DHD spool is built from solid 4340 material and is the toughest spool on the market. This spool will fit all Chevy/GMC & Dodge pickups with the AAM11.5 rear axle.
This spool is dimensional designed to function with DHD 38 axle shafts only. Yukon and various other manufactures utilize a different pressure angle on the drive splines.
