Couldn't load pickup availability
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. 2-1/4" hex nut with right hand threads. Compatible with 6-speed transmissions. OEM replacement reference 35241-06 nut + 35242-06 lock plate + 3595 lock plate bolts. Note: See 978488 JIMS or 925544 (MCS) for install & remove tool.
