I went to a aftermarket truck store and asked for some spring pins. they said that all they use is grade 8 bolts for all their lifts. I've read things about greasable springs being weaker and breaking though I've never had this happen. am I lookin for trouble just using a good quality bolt? I know they came from the factory with out greasable pins but I've always liked the idea of having the bushings move on the pins. I have to use 9/16 bolts which are smaller than the stock 15mm pins so I dont want to get even weaker by using a greasable pin that's too small to have appropriate strenght
I recently came across this same issue- 15mm/9/16" bolts. I'm using Ruffstuff too. Anyway, I discovered you won't find a 15mm bolt that long
