U bolt torque spec ?
What is the GM torque spec for leaf spring U bolts for a 57 Corvette ? Only thing I could find was a “generic” spec of 65 lbs on the Eaton site.
Got my new Traction Master bars today and I need to get em installed. I’m behind schedule on my Project X 57.
Thanks
Rex

Per page 14-2 of the ST-12:
Spring
U-Bolts...........55-60 Ft. Lbs.
Do not over tighten the outer U-Bolts, due to possibility of deforming the Axle bearing.
