Rear-end "Gear Swap" ........

Looking at swapping the 3:36's our for some 3:08's.. Anyone have a source? Info or advice on making this swap?

Thanks,
Dan

I bought a 336 ring, pinion and master install kit from this place. Was about $285.00 in all...looks like they sell a 308 also.

Cool! Thank you!

Particular mfg:
Yukon and Richmond are out there and I've heard that both are solid bets.

Van axles:
In general we got GM 8.2" rears with 1.400" pinion diameter. So if it says 1.628 or as such, that won't fit.

General RPO swap notes:
If you do that there's a somewhat expansive list of things you need.
In no particular order;
* New RPO (duh)
* Set of shims
* Pinion bearing
* Micrometer
* Paint
* Setting bearing
* And maybe a pinion seal... Don't recall.

Point is that it's not too complicated, however you'll need a ton of patience to set the backlash correctly. The Setting bearing is also a good to get, which is like $50 or so. It is necessary to be able to be able to setup your shims correctly, as you can remove it and measure/swap out shims multiple times to get a great mesh.
Otherwise you are guessing with pressing in a bearing, and destroying it when you have to pull them out if things are off.

Different between a thrown-together and properly-setup axle is also staggering. A setup axle will go for... ever, while a thrown-together axle can easily grenade itself in 500 miles or so from what I've heard.

Read around the internet, there are some great guides out there dealing with say, a Dana-44 or 60 swap. They are roughly the same concept, just different numbers.

Good info Xelmon! Thank you!

When you buy a gear set, make sure it's the Chevy 8.2 and not the BOP 8.2. The BOP won't work.
