I can't seem to find a 6 lug 14bolt close to me, so I wonder what all is necessary to convert an 8 lug to a 6 lug? I am wanting to narrow and 4 link it when I put it under the truck. I need some help cuz I really don't know where to start.

 

Find one that measures 67.5 wms-wms and swap to 6 lug 4x4 axles from a 1500.

New axles can be had for $200-$250

Check 2500 4x4 suburbans.

 

If you're going to narrow & link it anyways, then why not choose an axle with better aftermarket parts availability, and less unsprung weight?

The best reason to use a 9.5" 14 bolt is that it is a direct bolt-in. But you're not going to need any of that "bolt-in" advantage.

 

What would you suggest?

 

I don't know enough about his build or goals to make that recommendation. But there really isn't very much aftermarket performance parts for the SF 14 bolt, and he's going to be modding just about everything on it.

 

IMHO the 14 bolt 9.5 can still be built reasonably cheap compared to most alternatives and retain the factory brakes and function. The axles on the older units are much thicker and the factory lockers are plentiful and hold up better then there 10 bolt counterpart. If you look around you can usually score an eaton posi.

Best part is you can get most parts over the counter at the parts store too. Unlike custom parts which usually have to be orderd.

 

I have an 03 RCSB Silverado with a 408/4L80. I'm pushing in the neighborhood of 600 at the crank right now and plan on much more. I figured I could pick up a 14 bolt SF for a decent price (next to nothing) and build it accordingly. I am more worried about traction and when I find traction I don't want to worry about the rear end. I have the factory 10 bolt now with 3.42 gears and a trutrac. I have 4.56's to swap out, but was really considering a narrowed 4 link setup for future plans.

 

I like to find MOST parts at a convenient place, but don't mind getting the aftermarket parts as long as they are worth it. I'm not looking to build a 9 second truck, just something I don't have to worry about breaking when I play.

 

Why not swap the gears into the 10 bolt and take it easy.

4 link the truck later. Then you could build a 9 inch when you 4 link it.

A 4 link is not cheap and if your going to spend the money then do it right.

I am the first one to say go for it and use a 14 bolt bolt budget build.

The biggest down sides are the unsprung weight and the C-Clips.

Gear choices aren't as plentiful like the 10 bolt either.

There are no C-clip eliminators for 14 bolt either.

Your choice is going to depend on your budget and your end goals.

 

You just listed most of the reasons that a 14B might be the wrong choice for his build. With his power level goals and current traction problems, I'm guessing he'll have slicks. Most tracks are going to require c clip eliminators. Having disc brakes will get most of us through tech though, but that all changes once you're faster than 11.50

A Ford 9" would be a good option, parts are plentiful new AND used. Dana 60's are also plentiful and have a huge aftermarket too.

I just see everybody jump to the 9.5" 14 bolt, like it's the only answer. If you want a direct bolt in, it's a no brainer. Go for it. But, if you're cutting off the perches and narrowing the tubes & axles, there are better center sections to choose. Just my opinion.
