The blazer rear end will not swap into a truck, because the frame of a blazer is wider in the rear than a truck, and the spring perches are farther out than a truck rear, no matter what year axle. You can use the brakes from the blazer axle, but you need to get a 1/4 inch spacer to put between the axle and the caliper mounting brackets. Also the parking brake cables are different than your 89's cables. I'm trying to figure out how to swap in 2nd gen cables to my 92 truck. The 2001 4x4 4 door blazer I got the cables from, has a 107" wheelbase, and my 92 reg cab short bed has a 108.3" wheelbase. Difference of about a inch & 3/8". Should be close. The problem is: 1st gen truck's parking brake cable comes out through the frame on the inside of the frame rail, and has a threaded end. The 2nd gen parking brake cable comes through the floorboard, and runs along the outside of the frame rail, with a little cylinder shaped "lug" on the end. I'll have to check to see if the 2nd gen blazer's parking brake cable coming from the pedal will work in a 1st gen truck. If it will, should be golden.

1 QUESTION TO ANYONE WHO HAS DONE THIS SWAP.. does this make your rearend wider at all? and is it different for the ls1 or lt1? I really need it to stay the same size.... thanks

[3rdCoastCrawlin]

^^ Good question. Also, I'm looking at getting a LS1 rear-end off of a 2001 Z28 with 3.42's, but since it is off of a manual Camaro, it has no traction control. Should this be a concern or does it not make a difference? Thanks

It does not make your rear end wider. Without the spacer's the calipers won't fit over the rotors. Remember, the blazer's axle HOUSING is narrower, so when you put them on a truck rear end which has longer AXLE'S the caliper mounting brackets come up a little short.

The distance between the rotor center line, and the rear end housing mounting flange (where the caliper mounting brackets bolt up) on a truck is different than that on a blazer.

I don't know if the same rules apply for the LS1 / LT1 brakes. Maybe someone who has done that swap could shed some light on it.

Hope that clears things up.

hey everyone ... yes my computer did crash. i do still have the how to mentally if you guys are interested. Basically goes like this:

-open rear pumpkin and drain
-remove all brake drums and springs, etc.
-remove axles - there is a small gold colored bolt running left to right. that gets loosened and the big gold circle will come out (actually a big rod) --- DO NOT TRY TO REMOVE THE BOLT !!!. Push the axles IN and a c-clip will come out for each axle. Pull the axles out
-remove the 4 bolts per side to take the drum backing plates off
-install the ls1 or lt1 disc backing plates
-reinstall the axles in reverse from above
-reinstall the rear end cover and seal and refill
-put on the rotors
-put on the calipers and pads - caliper rubber hose screws directly on the metal brake line
-put on the wheels
-fill and bleed brake system

As a side note, the rear discs WILL push your rear wheels out about 1/8" - 1/4" or so

Hope that helps guys

Onyx, do you know anything about this?

[Onyx02XCabX]

the camaro read end is wider than the s10 by a couple of inches on each side. Also, you will have to weld leaf spring perches to the axle. If you even barely don't get it right, u joints will suffer. As for the internals if that is what you wanted, they will fit in the s-10 rear end.

You do not want the tration control rear end anyway.

So the Blazer/Jimmy rearend set up is different from the S10/Jimmy. But that doesn't change anything as far as swapping to LS1 or LT1 disc, right? All the brackets and stuff should be the same on the ends? Just different axles and housings.

GM is VERY interchangable. Think of it like this, GM is such a huge company, that if they were to design, and build EVERY car/truck (made up of a lot of parts) unique from one to the next (including the parts they're made of), they would go broke. So what they do to save money, and maximize profit, is start with a "platform"on which to build multiple vehicles from, and use Most of the same parts (with a few tweeks) to build these multiple vehicles, all while giving the vehicles they'er own identity in the form of unique styling. Camaro/Firebird is one example. S-10/S-15 truck/blazer. Cavalier/Sunbird/Sunfire, ect. The rear axle that is in the Camaro is the "same" as the S-10. Only the camaro rear has beefier axle shafts, it's wider, and has coil spring perches. It's not Identicle, it's just the same design. These are probably the same design rear ends that were in the old rear wheel drive monte carlo's, regals, grand prix's, and olds cutlass cars of the late 70's, 80's, and early 90's. Why the same? Reliability, they're proven, and cost less to modify the existing design to fit a particular vehicle, than to start from scratch, and design, test, improve, and approve a totally new design for every day use in a new vehicle.
With that said, ALL the S-10 rear axles are the same (identicle w/ very minor changes) from the first one, to the last one. Same design that is in the camaro. If you have the same design rear end in nearly every rear wheel drive vehicle you make, it becomes very easy (and cost effective) to tweek the design to fit a particular application. Modifying only length, width, or highth, and the way it is attached to the different vehicles. Are you following me on this one? Brakes have they're own design, drum, disc w/ parking brake integral calipers, disc w/ drum type parking brake, ect.
So to make these brake designs fit a rear end design that's in nearly every vehicle you make, Say it with me....You make all the different brake designs mount to the rear end design. Which is especially lucky for us when it comes time to upgrade to better brakes!

Happy brake upgrading!!

bump with a question. i was looking at a camaro a few days ago and thought about this swap, but figured i would be impossible, then i searched and found this thread, so i'm doing it soon. i work at a body shop and my boss has a wrecked 96 transam with lt1 and 6 speed (no traction control, right??) and also a 99 camaro z28 with LS1 and auto (traction control???) the camaro is really bad and the brake rotors are sheared off half way, so which one should i use? i know the ls1 cars had better gear, but would it be worth it if the rotors are messed up that bad? i'm doing this to a 99 with a 5 speed. i might just throw the gears in there too while i'm at it, since this 2.2 isnt going to be in for long. opinions?

[acrofobia]

Is it also true that this swap kicks your wheels out a 1/4" on each side?

[>X<]

yeah, it pushed the wheels out 1/4. can someone explain traction control to me, its like electronic limited slip right? what gears come in the camaro tbird rearend, i can swap those in too right? are they posi?

[XtremeVintage]

hey oynx... new to the site but you seem to be the man to talk to on this thread! hey i found these on partsamerica.com....i searched under '02 camaro z/28 and found reman calipers with the brackets for $61 apeice...will these work?

http://www.partsamerica.com/ProductD...e=5003&ptset=A

any help is appreciated, i'm going to do these this spring once it warms up here in ohio.

oh and also, did you say you could also purchase the camaro brake lines to work with this? i'm assuming it would be the lines from the block on the axle out to the calipers? am i correct?

thanks!

[HofinaterSS]

dude this thread is really old! Awesome thread though...i'm going to have to pull the rear brakes off the firebird in my local junk yard now

[corybride]

Hey guys, me and my buddy both have a set of these f-body rear brakes for sale...

[HofinaterSS]

so if im reading this right...i can find a 4x4 s-10, or blazer with disc rear brakes and take off the rotors, calipers, and mounting plates, and just bolt them on my truck?

[INTRUDER]

Hey guys, new to the group. Lots of info here!!! Too cool and thanks so much!

Now my Q: I am starting a V8 swap into a 94 S10 and definately want rear disc. Have an uncle that works for NAPA and get my parts for COST, Rightous! Since the swap works on the rear, will the bigger F-body front brakes swap out as easily? Or do you know of such a conversion kit to swap out the calipers and rotors?

Just in case this has been posted already, sorry. Don't flame me please. TIA!!!

[XyellowX]

i just upgraded my rears to c5 brakes using the brackets off of ebay and my caliper cage is super close to the backside of the rotor. just wonderin if this is normal? about how much space is susposed to be between the rotor and the cage?

[XtrEmeHeAt]

Onyx02XCabX, could you send me those pics and instructions aswell... Was looking into the swap for my blazer jus wanna see what im gettin into.. Thanks

xtr3mehe4t@yahoo.com

[Onyx02XCabX]

Wow this thread was brought back to life I have long since purged the info from my numerous computers over the time. The "how-to" in this thread is still accurate.

This really is a straight forward bolt-on conversion. I live in the DFW area now so if anyone is in the area nad wants to meet up, I can show you what you mess with on your truck. Also, depending on the weekend, I would be willing to help.

eBay Motors: Firebird Camaro Monte Carlo SS GN S10 rear disc brake (item 220106520419 end time May-02-07 09:21:15 PDT)

won't these work on a newer rear end

[ridered600]

which is easier(more straight forward, i guess)....modding the existing e-brake cable or replacing the cables with the Camaro/TA cables? Starting to check bone yards and when i find a car I only want to make 1 trip

[SONOMAZRX]

You can buy a rear drum conversion kit from SSBC but it will run you between $700-$800. But you don't have to worry about the bulls**t. Bolts right on

[BudRacing]

I'd rather save $400 and worry about some BS. And keep my parking brake.

That's fine if you have the skills and tools to do so. I agree, just giving some options to the people who cannot do it on their own.

[BlownGP]

I know old post..

I think I got most of it figured out, but my only questoin is.

oynx... when you say ls1 or lt1 disc backing plates.
Do you mean "caliper brackets"?

Thanks
Steven

[the_dam_man]

I am planning this swap for this fall when i put in the zetel diff and new gears. figured if I have it all apart then.....

plus they will go good with me 12" front brakes I am putting on later this month. (B-body spindles and 1LE rotors with some global west arms.
