I haven't pulled the springs out from under my truck and I need to order the center bolts to install an AAL / Add A Leaf to the rears. None of my local McParts stores have them in stock so I have order them. A "search" of the site hasn't helped. Does anyone know what the diameter of the bolt is supposed to be? Does anyone have a pair of springs off their rig or one that's loose from a stock pack? TIA!!
Leaf Spring Center Bolt / Pin - what diameter?

Originally posted by wiley-moeracingNapa should have them, either 5/16 or 3/8.
I've found those sizes, but which one is the correct one? If I go with the 5/16" then I have a 50/50 shot, but they could be too thin and with the 3/8" they could be too large. I could buy both sizes, but I need two sets and dont want to get stuck with special ordered parts I cant return.Originally posted by will eKeep in mind. Getting old is easy. Being old is hard.

Originally posted by wiley-moeracingMy local Napa keeps them in stock, no special order needed. They should be 3/8 if it is a later model. You should be able to see the bottom of the bolt through the leaf spring to verify what you have, same front or rear.Originally posted by will eKeep in mind. Getting old is easy. Being old is hard.

If your local NAPA causes that much trouble, I suggest you get them online. I've only needed these bolts for my CJ-6, and they were 5/16" size. The CJ springs are really narrow (1.75") and I would guess that the FSJ springs would use 3/8" bolts.
I bought these - https://www.amazon.com/Rancho-RS8127...80M/ref=sr_1_6
and these https://www.amazon.com/Rancho-RS8128...3A/ref=sr_1_11
and threw the 3/8" bolts in the junk bin, IIRC.
eTrailer has them cheap, but maybe not much cheaper than the Rancho ones when you add shipping.

Jeep used both, depending on year/spring rating/etc.
Who knows if your springs are still stock?
I have seen both sizes used on SJsTony

Yeah, the head goes into the seat on the axle, no? Meaning the end of the bolt should be visible in the hole in the clamping plate???
Nut could even be removed?Sic friatur crustulum
