YJ springs into a CJ

Nothing but a can of worms. Really. On hunt for shackle/spring eye bolts. Zero luck. Summit. 4 wheel parts. R&E fasteners, granger and fasten all. All zip. Need 1/2” x 4.5” with shoulder of 3 5/8. All are too short or too long. FML. Project comes to screeching halt. Welding on new spring perches, cutting off and new shackle hangers and new front one off fixed spring hanger foR the SOA and SR. Thanks to crasher time for engineering but still a hot mess. Then we get to tear back into the rear pax to learn why it’s eating bushings and twisting shackles….

Buy longer with correct shoulder and cut length if you worry about thread been inside shackle.
McMaster has some

tnx, will try them. R&E and Fastenal both no luck. Cannot believe its so hard to find a 1/2" x 4.5" with shoulder to clear the shackle plates.

Probably because it is not standard bolt. Here is 5" with shoulder length you looking for.

Can you buy a longer bolt with enough shoulder and then run a die over it to take the threads down to where you need them and then cut the bolt to length?

will keep looking. the length can be a mile long, IDC, just that the shoulder portion is 3.75". no more, no less. heard cashman equip sells bolts. Spoke with Rubicon Express, rough country and even WFO, no luck. they say just use the old YJ bolts, which of course i do not have.

Springs and hangers are in correct position. Snag is the P side. The spring perch is cast into the axle housing near the center section. With the 2” CJ pax it was close. Now with 2.5” pax it’s too close. Had johns make up a new inner u bolt with some bends but it’s not enough. Might try more bends in the shop vice or try something completely different. Ideas?

Damm Mark, long time buddy! IF your going that route slap some anti seize on them threads before tightening to help shape before you do your final torque , so you dont stress the threads out to bad. once thats done squirt it off with break clean in-stall with new nuts.
