I replace the K member and torsion bar cross member isolators with Energy Suspension components.
Factory service manual calls out 50 ft-lb for the cross member isolators.
Where it gets fuzzy is that it appears to call out 75 ft-lb for the torsion bar cross member isolators bolts.
This is the exact verbage:
"Position torsion bar isolator assembly over the hex ends of torsion bars and install two bolts. Torque bolts to 75 ft-lb, and tighten to specified torque".
Does this make any sense? 75 ft-lb seems excessive. Thoughts?

Follow the suppliers instructions after all they made the product and should know them best.

IMHO

is not the same torque down the stock rubber pieces than the Poly ones. Am I wrong thinking this?

I agree with you you Nacho. Energy Suspension instructions state to use manufacturer torque settings.
