Can't find any number on it. I.D. info plate on glove box door only states number of springs and axle manufacturer (Eaton). The suspension is not in my service manual. Not that I could find. Trying to find rubber bushings for torsion bars. Thanx,

Would have been special order. | | | | | Joined: Nov 2005 Posts: 6,101 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,101 | Hy GMCPic, could you post a picture of your suspension? Your truck probably has rear suspension with a radius rod to control torque, could that be the "torsion bar" you're looking for bushings for?

Leaf springs have shackles at both ends, rods connect in line with the frame under the forward spring mount and connect to the bottom on axle spring clamp underside of axle. Ends of rods are offset to connect under frame and under the axle.
It reminds me of an early Hendricks setup but I do not believe it is Hendricks.

Original spec sheet calls them radius rods. | | | | | Joined: Dec 2009 Posts: 52 Shop Shark | | Shop Shark Joined: Dec 2009 Posts: 52 | GMCpic, check page 351 and 352 of your maintenence manual. It shows a picture on page 352. | | | | | Joined: Apr 2001 Posts: 268 Shop Shark | | Shop Shark Joined: Apr 2001 Posts: 268 |
