Does anyone have a spreadsheet with all the torque specs for these T1 trucks (I.e. leaf springs, lug nuts, sway bar links, etc)? I know there are several threads on the K2 trucks... would like to do a once over in my 19 now that it’s nearing 5k.

Anyone???

I'm changing my rear spring blocks and not sure of the u-bolt torque.

I heard that the factory U-bolts are really a one time use kind of thing. When I changed the blocks on my K2 truck, I bought a set of Zone grade 8 u-bolts. Much beefier and made me feel better about the taller blocks.
