I have a 85 blazer with a 6 inch lift/36 inch tires and am sick of my driveshaft hitting rocks. Its got a 10 bolt in it now with 4.56 gears. What do you guys think is my best high pinion rear option? Strength/cost/driveshaft height/oiling issues considered I live in Wyoming and don't know anybody locally (as of now anyway)to go check any out. Thanks for any help.

I really don't think there are any reverse cut axles that are strong enough to be used in the rear of a full size vehicle.
I have seen a reverse cut '60 in the rear of a K5 once, so it's been done before. The guy cut up a Ford front axle to make his rear axle...and built it himself.
Keep in mind that your pinion will only go up approximately 3" by this swap. You might be better off with bigger tires instead.
Hell if you've got a 10 bolt now, anything is an improvment just about.

If you have the $ resources, go with an aftermarket center section like Tera's CRD, Currie, Rock Crusher or Dynatrac's. They are designed with better oiling and such.
Or if you have alot of extra funds.... Mog portals!!! /forums/images/graemlins/smile.gif

I'm starting to think this guy is a troll.
If you're wondering about high pinion axles, do a search on www.pirate4x4.com
There is only one person making a true high pinion 9" and they just came out recently.

which do you think would be stronger the hp9" or the hp60?

If you go with a Currie HP9", then the 60 is definately strong as the Currie unit uses a smaller carrier than a normal 9". It's somethign like an 8.8" or 8".....
One company did just come out with a true HP 9" like TIm said. Do a search over on Pirate for it...
Tim - Why would you think he is a troll?

I think he's the guy creating this high pinion 9" trying to expose the product. I can't really blame him, either.
Just seems kinda weird to me that someone with 5 posts and a rear 10 bolt is asking about a high pinion axle.

Most of my buddies and I have 80's blazers and love our gm's. When we lift them the the driveshaft gets so much angle they shake. We've tried more pinion angle less pinion angle sometimes its on accel sometimes decel. The c/v on the t-case end seems to help but you grind the heck out of it to get any travel. We've tried replaced the bushings in the t-case output. It's getting to be a drag. I'm thinking I'd like to try and fix this one last time and be done but don't know which way to turn. /forums/images/graemlins/confused.gif

I'd go with a Tera CRD 60 houings and call Jesse at High Angle driveline for a CV with more movement so you dont have to grind the stock! He has them up to 80* I believe!

if he's going to get the housing from Teraflex, then he mind as well get them to build them the whole axle, or find another place. it will cost more than 2000 dollars after adding in quality aftermarket parts to match the rest of the set up.
if you just want a HP front axle, use a stock ford hp 60, and upgrade whatever you want, then you have all the stock parts as spares...

Everyone is missing what he is looking for. He stated in the first post:
"What do you guys think is my best high pinion rear option?"
He could save a little money if he can assemble the rear himself and install the gears. It's only about $200 to retube an axle, but then you got to add on installing housing ends....

he also said:
"Strength/ cost /driveshaft height/oiling issues considered "
I dont understand why he needs such an expensive after market HP rear axle... sure he hits the driveshaft on the rocks alot, but it will be cheaper to buy a few spare driveshafts instead of buying a HP rear axle...
