Holly stored energy (Front spring change) - The 1947 - Present Chevrolet & GMC Truck Message Board Network

They were a little tough going in.

Had to compress the spring 7" or so
Drop the control arm from the cross member
Set the arm with spring in it under the pocket
Jack it up a little to set the ball joint and shock
Jack up the cross shaft with a block of wood
Bolt it all together
Release the spring

Moroso Sring 47140
240lb rate
17 3/8" long

Truck sits about 3/4" higher than it did with the 14.5" 350lb springs.

Yesterday I pulled the ball joints out of the upper control arm and mounted them from the bottom side.

I have about 6" of true apward travel with out the spring settled yet.

Heated up the tires on a test road and left. It tops the suspension out now even on the 70/30 front shock setting. I was using the 90/10 before with the other spring. I tried to slow down the lift with the 70/30 setting after taking it for a ride in the 90/10 setting..
