JIMS Cruise Drive Mega Nut

If you tinker with your bike, install or reinstall your driveline, you know about the issue of your rear pulley coming loose from your main drive gear.  Years ago JIMS, the leader in performance tools for your Harley, designed the original “Mega Nut” complete with a machined clamping face profile and additional locking holes for a more precise way to secure the pulley nut.

JIMS® Cruise Drive Mega Nut No. 1733 now incorporates the same advanced design for late model Cruise Drive transmissions and when installed correctly you can feel confident that your rear pulley will never come loose from your main drive gear. The left hand thread Mega Nut can also be secured in several additional places with a simple drilling and tapping operation. JIMS® Cruise Drive Mega Nut No. 1733 is machined right here in the U.S.A. from the highest quality material and has an MSRP of $77.30. For more information visit JIMS USA or call 805-482-6913.

    road rash,

    Every bike we build has a chain …. what we do is turn the outside perimeter of the nut down somewhat and it slides right in place …. then install the bolts to lock in place. Piece of cake.

    Why would any one want to buy a new part and have to machine it to fit,thats bullshit,make them to fit .if it’s that easy like a piece of cake then let the manufacturer do it instead of passing the labor on to the customer…….Over, Over and out….

    “Sum fitting may be Required”, that’s why we call it “CUSTOM”!! Wiz
