      Piece of mind

      Perfect fit, no worry about sprocket nut coming loose and causing damage to man or machine.

      Mega nut

      It makes aligning the lock nuts up so much easier. Looks good enough to leave the cover off after I used Lowbrow chain conversion kit.

      Solid Item

      Rather than reuse the stock locking nut (it’s 20years old) and retainer , I ordered this unit. It is really nice and went on solidly. Design makes sense and lined up perfectly.

      Well engineered replacement for multiple parts

      Nice add on, easy install. Replaces 2 parts and looks way better.

      Mega Nut Sprocket/Pulley Lock-Nut for 1993 & Up H-D Sportster

      Far superior to the OEM item(s). Spun on easily by hand and torqued to spec. Could not be simpler to use. Would like to give a shout out to Todd's video on fitting the Lowbrow chain kit which I purchased some time ago. I was encouraged to go the distance on fitting the chain after my belt was contaminated by oil. The decision to purchase the complementary sprocket nut later has proven to be positive.

      Very well made!! Unfortunately, it’s not compatible with my Baker Drivetrain pulley, so I’m going to have to return it. I didn’t realize that it was different than stock.

      OEM nut kept loosening up and chattering.

      Cool, does what it supposed to do. The surface area on the nut is pretty small, so that was a little bit of a pain in the wiener. But I gotter. Toss the stock nut on retaining plate, this one is better.

      Sportster Mega Nut

      Much easier to torque down than stock and a better look if you are leaving the cover off.
