Hey guys im posting to let all know that a 1998 Express van 2500 6 lug 14 bolt 9.5" WILL work in a 2005 Silverado RCSB. The only thing i had to do was cut off the bump stops that are inboard of the rear end perches, had to cut off and move the perches themselfes and make a modification to the left rear shock mount. everything worked right down to the drum brakes since mine already had them, they are bigger but still worked.

 

sweet action. i'm guessing these're easier to find than the 2500LD axles.

 

Depends where you live I guess.

The hard ones to find are in the 2500 suburban

 

picked it up from a local u pull it wrecking yard, i think the wheel mounting surface was a 1/4" to maybe 1/2" inch narrower than the stock 10 bolt and i set the leaf spring perches 2 3/4" in from the 4 bolt flange for the drum backing plate and then i set the pinion angle at ride height which ended up being 0 for my truck, it is vibration free all the way up to 90mph.

 

A couple pics it has a DJM 4/6 lowering kit and 245/65/17 tires

 

Are they desirable because OEM disc with the dual piston calipers?

 

Any pics of the modifications you needed to make?

 

Nope, work trucks are on the road more so they approach 300k much faster and people are replacing them. Plus there more likely to be involved in an accident from being on the road more.

Where as the 2500's suburbans are usually a weekend warrior Vehicle's at this point as people drive more fuel efficent vehicles to there day job...

 

but i thought all the HD suburbans had 8 lug axles... maybe i'm wrong.

 

They are 8 lug. But you can use the OBS 6 lug axles in them. Just have to weld on new brake mount flanges. Far easier than cutting a bunch of brackets off and lining them all back up.

The more cutting and welding you do, the more you can distort a housing. If you don't have a line up bar to check it you may have problems down the road...

I would never do another OBS housing again. It's more work and not worth the hassle when I can use a housing that bolt's in, Uses off the shelf axles, and only needs flanges to make the stock 1500 brakes bolt up.

The OBS housing requires the removal of nearly every bracket and then you have to clean up the mess unless you like the hacked look. Not to mention the OBS drums are hugh and weigh a ton in comparison to the newer stuff.
