Leaf Spring Questions

[9car]

how tight do you guys fasten your u bolts on the housing/springs ? i have never fooled with leafs before and have shims and lowering blocks that i dont want to come loose , but dont want to overtighten it because i read that effects spring rates ? just looking for some input

thanks

torque 1/2 u bolts 45 ibs

landrum leaf springs technical section states 45 ft lbs torque for a 1/2 inch u bolt and 20 ft lbs torque for leaf eyelet bolts and i also double nut them so they dont come loose,i hope this was useful for you.
