Leaf Spring Perches/ Location - The 1947 - Present Chevrolet & GMC Truck Message Board Network

JNJchev77 · 02-08-2011, 07:02 PM

Had to remove the perches off my 12 bolt, they were hacked off and welded back on under the axle as a "rigged" flip kit, prior owner... Anyway, does anyone know the distance between the two leaf spring perches? Center hole to center hole? Need to weld new ones on and cant seem to find any info on the measurements...

You'd be better off setting the rear and perches under the springs, snug the u bolts up, set the side to side, set the pinion angle then weld them in place.

Thanks dwcsr, however, I should have explained a little more... I'm actually adding PB 4 link rear, so using your method wouldn't work for me, sorry bout that, but thanks foe the reply! Anyone know where I can find The measurement or know of an alternate solution?

Measure from center to center of the bag mounts on the bridge assembly... this will also be the center to center measurement of the leaf spring perches. I would recommend mocking it all up and tacking the pads in place once all measurements are confirmed... then pull it apart and make them permanent!
