I'm trying to find six bolts, 4 1/2" long, with M12x1.25 thread, grade 8 equivelant for my transmission crossmember lift blocks (EA81). Anybody know of a good vehicle that would have these bolts in the suspension? I'd like to find some at PAP.

People who build lifts usually don't go that route.

 

This is the common route.

 

It's been off road tested, very rigorously. I'm having problems with the body itself giving out...that bolt method is %100 still.

Also, those are standard 7/16" bolts on the bottom.

The only problem with that setup is the bolts into the body are very hard to tighten and access in certain spots. I do however have that exact type of setup on mine.

 

Id just head out to the junkyard and look at the Toyota and nissan trucks.

I found some suitable for my 3 inch blocks at the local hardware store. Grade 5, but whatever, there are 6 of them, and I'll be careful not to ram into stuff too hard.

 

THe two bolt per block thing is a pain in the butt.

My blocks are homemade with 1 1/2" x 1 1/2" steel stock with square washers welded to each end, with a total of 3 3/4" length. So, I have to use one long bolt per block. Will check out Nissan and Toyota trucks, thanks.

Duh....

Is tying the blocks together standard? Cuz mine are not.

They don't have to be tied together it just adds some extra strength. As for the bolts, I found a store near me called Fastenal. I'm sure there are locations other places too. But they had all sizes in all grades in all lengths! I got some 7 1/2" grade 8 metric thread bolts that were somewhere around 1/2". So they are out there. Good luck!!

Ive used toyota 22r headbolts for that lift

I have too, aren't they a different thread pitch though? Because I've had to run a die down the head bolts.

I checked out a few head bolts at Arlington PAP while getting a new flywheel for the Legacy(f'n burned it bad!!!), Mazda pickup headbolts and early 20R headbolts are like 10mm, so they didn't work. Suspension bolts don't seem to be long enough anywhere, but Legacy rear bolts(the long rump roast ones at the bottom of the hub) are perfect diameter and thread pitch, but way too long. Gonna keep searching. Gotta go to Lynnwood PAP to return some cores. The black Brat there had.... GCK's!!!!!!!!!!!!!

Tacoma screw wasn't bad. I had to get one from ace hardware that ended up being way over the top expensive.

Yeah, I have a Tacoma Screw Products locally. Might stop there and check them out if all else fails. A bonus for going there is I can go next door and blast some heat at the range.

Too long isnt a problem. Thread a die onto the bolt, cut the end off with a rotary or a hacksaw and then run the die back down to the end to clean it up. If its shouldered you might not be able to do this if the shoulder is too thick.
