Bought sets for my two axles from Morryde. Heavy duty shackles and everything I needed. One of the bolts had a grease zert in it.... but no outlet hole in the middle of the bolt for grease to come out. I called a local RV/mobile home parts place and they had everything there. Wet bolts/copper sleeves/ heavy duty shackles.... same stuff morryde sent me.... but a LOT Cheaper in price. Same quality parts at a cheaper price. Look/call a local RV parts place and see if they have what you might want.
