Nut with a built-in lock plate. Never a loose transmission pulley again; that is what the MegaNut is all about. The built-in lock plate in the JIMS MegaNut works with all OEM and aftermarket pulleys. Some aftermarket pulleys may require an additional hole to be drilled and tapped in the pulley; so the lock bolt can be installed. 1-1/2-24 left hand threaded. Will not fit 6-speed models. OEM replacement reference 35211-91; 35211-91A; 35211-91B (nut); 40251-92A (lock plate) and 3594 (lock plate bolt). Note: Left hand threaded. Note: See 978332 (JIMS) or 925544 (MCS) for install & remove tool.
