I'm relatively confident that Chevrolet didn't offer a full locker in their rigs. Most either came with an open differential, or a limited slip (which by this time, is most certainly completely worn out and about as good as an open diff).
The '89 FS Blaze comes with a Corporate 10-bolt rear axle, which is a c-clip design, and notoriously weak. Here's an article we did several years ago about the axls and what you can do to beef the up.

Hope this helps,

PS - your front axle is also a 10-bolt, but with an open differential (they didn't offer a limited slip front axle).

Thanks ChevyMan! It was a real eye-opener for us when we started interviewing experts in the industry, and we found out how strong a 10-bolt axle is, and can be.
While we haven't had that truck in our stable for a few years, it did take quite a beating and the axles held together perfectly.
Regards,
Rick |

As a front axle the 10 bolt is not bad and while you can install stronger axle shafts one of its major weaknesses in the housing itself and lifts with big ofset tires place even more stress on the housing even when static and a lot more of road so if you plan to play hard off road in a big truck, you really need more than a modified 10 bolt because I have seen housings fail. One cheaper axle upgrade is if you can find one in a bone yard is to use the front axle out of a old fullsized Jeep pickup because it has a stronger housing than GM, Ford or Chevy used and it will take more abuse before housing fails and with upgraded internals it can be a pretty tuff cookie. BTW, A D50 is nothing more than a D44 in a stronger housing with a bit bigger axles. |

| My stock 10b's went to trash before I could save em, bent the tubs and blew the gears and shafts. I am horrendous to my poor K5, I feel bad for it most of the time!!! But since then I put a 14b in the rear (full float), and a HDD44 in the front. The D44 has held up wonderfully, but I know it is only a matter of time. Unless I make a truss for it. But I have a D60 on the way soooo, well you know..why bother right? |

| For what it is worth, if you can find a D50 out of a ford it is is nearly the equal of a D60 and sometimes over looked and if you want a serious front axle, get a AAM 9 1/4 solid axle out of a 2003 or later Dodge as its housing and knuckles are massive and a D60 pales next to it. (Dodge starter to use them quietly because the weight of the CTD engine was beating the D60's into a early grave in knuckle areas. |

| Yea, I have heard the same thing. And I agree, in fact I remember having a conversation with a friend about trying to find a wrecked Dodge somewhere and yanking the undercariage, caus you know the CTD will be long gone. What I wouldnt give for a CTD to put in my K5!!!! Man that would be a fun rig!! I have no doubt that I would wrap my truck into a knot with it!![:D] |

Quite honestly it would be a bust offroad with a CTD in it. That extra 600 to 700 lbs up front would not do you any favors in the short wheel base and a strong small block with deep gears would run circles around it off road and a big block properly geared would clean its clock. Another thing is that it takes a lot more water injestion in a puddle to trash a gas motor than a diesel. |

Great points, but it's not easy to get aftermarket parts for it. For an '89 Blazer, a D60 is likely a better bet as you'll be able to get 4340 axles, all sorts of locker options, hub options, brake options and so forth.
I'm not arguing that the AAM isn't a better axle, just that it will be hard to find aftermarket parts for it.
...but then again, one could argue that you might not need aftermarket parts. [)] |

Not sure what parts you are talking about that are hard to get. It uses a GM 9.25 IFS ring and pinion so that is no problem and the axle is so massive to deal with weight of CTD that you will have to work pretty hard to break it. (you will likely break a D60 long before you bust the housing up on that axle) Only one real minus here, no lockout hubs and a after market kit to install them is about 1600 bucks last I heard because of hub design spindles, hubs and stub shafts have to be changed. |

That's one of them.
There are also a limited number of deeper gear options available for that axle. Plus, while the R&P gears are the same, there are variances in the carrier design which make it hard to find various types of lockers.

Last I checked you can get up to 5.38 gears for it (same as GM 9.25IFS) which is enough fo any tire combo it would be solid with. Also far as lockers, I have not researched it but I am not a fan of front lockers anyway as they are good fr distroying front axle ujoints on striaght axle in locker turns because not only are you dealing with different rolling radius but also the fact that the ujoints in front axle are not constant velocity when bend past about 3 degrees (it gets worse the more you bend it) and this adds to torque wrapup and strain and steering wheel whip and something sooner of later will give. Also rmeber that when tires as skidding for a locker in a turn you actually have less effective traction to propell vehical. They are not the cure all that some claim. Years ago I had a setup that you could apply brakes to sliping wheel (line locks) and force power to better wheel) and it worked pretty slick in a tight spot. I may try this again when I restore my J20. It is pretty easy to do on front axle, rear axle is more challanging because it usually has one line for both wheels on axle so you need to run dual lines to it and place line locks up in chassis. |

Cutting brakes - I've used them on and off for years and they work great. I use them for other reasons, but yes, in an open-diff or limited slip setup, you can use them to help.
Regarding lockers - see the other post.
