FZJ80/LX450 tow hitch bolts size? bolt specs?

[DLPDLP]

Have an OEM hitch, just need bolts and can't find bolt info. Assume grade 8 but diameter, length, threads? Thanks

IIRC, they are M12x1.25, not SAE, so not grade 8, I would use at least 10.9, preferably flange head.

I have been running this same setup for 7-8 years. I occasionally pull a 1400# hummer trailer with a couple tons of rock for trail repairs. This also includes some serious wheeling, so definitely working it hard. I am running 4 of those 10.8 bolts holding the hitch, no problem. 2 of the 4 holes in the crossmember have weld nuts in them, but they were pretty rusty, so I knocked them off and use 4 flanged bolts and nuts. I am also running an early Slee rear bumper which wraps around the rear crossmember really tight and has the same match in my 4 holes, so I am running a double thickness back there. No problems so far, and I usually check torque on those after each heavy run.

Wanted to be sure, I have a Lexus hitch, frame mounted 6 bolts sits atop frame. Not the 80 bumper 4 bolt crossmember hitch. Thats the bolt specs you shared? Frame mount 6 bolt? Just makin' sure. DLPDLP

I actually also used my bumper mount pretty hard with my firewood trailer but nothing heavy on highway. I question the non-tow-rated info on the cross member setup. I now have both and need bolt info for the 6 bolt through frame setup. Thanks!

I need this for the 100...wonder if they're the same! Haha.

 

[DLPDLP]

Don't know about the 100 but here are the 80 specs from a Cruiser Master Mechanic

12mmx1.25 pitch I think 55 or 60mm long.

Thanks to all! Wheel on. DLPDLP
