1988 1500HD. 9.5" semi floater with 6 lug axles. New bearings, original gears (3.42), and an Eaton Truetrac.

 

Glad to see some updates on this thing, definitely one of my favorite builds. Your tire fitment issues are due to the 14b being a bit wider right?

 

Love this build, what's your goal as far as time with your current setup?

 

The 14 bolt is narrower than the 10 by an inch total I think, maybe it's a half inch. I just meaured it really close to get the biggest tires possible. The truck can really use the 1 inch lift in the rear. The shock mounts on the 14 bolt are shorter than the 10 and the shocks are bottoming out way too easily now.

Thanks. Hopefully I can get somewhere in the low 11's with the current setup. Maybe switch out the shocks or something, it has no weight transfer to the rear.
