S10 rear end for 1953 210...

I am getting prepped for a motor swap on my 53 210 and I am in need of a rear end. I've read that the S10 is a fairly easy rear end to swap out and I believe bolts right up?

If this is true, will an S10 Blazer 4wd rear axle work?

Much appreciated!

 

Oh and if it matters, it's from an 85 Blazer S10

 

I don't tnink it "Bolts Right up".You may have to move the spring pads
and adjust the Pinion angle. Have one in my 57 Chevy and that what I had to do. Good luck. Tom (Tired Old Man)

 

Alright, then I'll just stick with my 68 Camaro 10-bolt rear end.

 

I would stick with the 10 bolt.

 

I was going to put an s10 rear in the 54 210 that I have been working on but it is too narrow to allow the backking plates to fit around the frame at full drop. so I went with a 72 nova 10 bolt.

 

you need an s10 4X4 rearend. you have to weld up $10 perches. Its super hard.

 

Used a 70 Nova in 53 .

 

here's my S-10 4x4 rearend before shocks.. perfect width, just remove and weld on new perches...

 

Have had good luck useing 8in"granada rear.58"wide dropout centersection 4.5 bc.Jimmie

 

Thanks gsport, that looks great man!

 

So is the rearend out of an S10 blazer the same as the S10 truck?

 

I may be wrong when I say yes,but it must be from a 4X4.TOM (Tired Old Man)

 

Yeah, the one I'm looking at is out of a 4x4 S10 Blazer...it's a 1985.

 

then it is correct.

 

Great 53sled, I'm going to pick it up tomorrow night then instead of getting that other 10 bolt that may not even fit. Plus this one has good brakes where as the other needed everything for about the same price!

 

What gears can I expect and will it be posi since it's out of a 4x4?

 

S-10 rears are junk. Go with a Chevy 10 bolt.

 

Is it 5x4.75 as far as wheels?

 

s10 rears are 10 bolt. There are different versions. 7.5" 7.8" 8.5" etc. Many people push 300-350 horse motors through them in the little truck.
Thanks for playing.

yes, your wheels will fit.
common 4x4 ratios are 3.42 and 3.73, very few are posi.
only easy way to know is the glove box id. unless you crack it open and inspect.

 

Thanks 53sled, I see you becoming an invaluable resource over the next few months!

 

The blazer and pickup S 10 rear ends are not the same width. One is narrower, can't remember which one is,but have put S10 rear ends in a 50 Chev sedan and a 53 Chev wagon a few years ago. I'm thinking if you said the blazer one you have is to narrow then get one from a pickup. The ones we used were about 53" measured backing plate to backing plate. Hope that helps.

 

here's the codes as to what ratio and rearend you have.. the information is found in the glove compartment.. it has to be from a 4x4 as the 4x2 has a much narrower rearend...
GU1 : AXLE REAR, 2.41 RATIO
GU2 : AXLE REAR, 2.73 RATIO
GU4 : AXLE REAR, 3.08 RATIO
GU5 : AXLE REAR, 3.23 RATIO
GU6 : AXLE REAR, 3.42 RATIO
GV1 : AXLE REAR, 2.73 RATIO
GV2 : AXLE REAR, 5.83 RATIO
GV3 : AXLE REAR, 3.08 RATIO
GV4 : AXLE REAR, 3.36 RATIO
GV5 : AXLE REAR, 3.55 RATIO
GV7 : AXLE REAR, 4.11 RATIO
GV8 : AXLE REAR, 2.72 RATIO
GW2 : AXLE REAR, 2.56 RATIO
GW3 : AXLE REAR, 2.56 RATIO
GW4 : AXLE REAR, 3.31 RATIO
GW5 : AXLE REAR, 2.73 RATIO
GW6 : AXLE REAR, 3.27 RATIO
GW8 : AXLE REAR, 4.10 RATIO
GW9 : AXLE REAR, 2.93 RATIO (DUP WITH GU3)
G80 : AXLE POSITRACTION, LIMITED SLIP

It depends on what you are using for a motor. The one we put in the 50 Chevy had a 305 with a mild cam, edelbrock dual plain intake and 600 carb, the 53 wagon has a350, intake and 650 carb. The one in the 50 has been in there for 9 years with no problem, it is still running and was driven alot, went from Chicago to Back to the 50's in St Paul for 6 times running to to 85 mph. It will be going there again next summer the wagon has been driven for two years with no problems. Againit depends on the motor and how you drive it.

 

Can anyone verify if the Blazer and pickup have different width axles? Or is it just 2x4 and 4x4 are different.

 

just 2x4 or 4x4. blazer is a short wheel base s10 frame with a different body. just make sure some one didn't put a 2x4 rear in before you get it unbolted. about 59" wheel mounting surface to wheel mounting surface.
2wd is only 54"

I have the 1988 S-10 Blazer "Guv Lock" 4X4 3:43 rear end in my 57 Chevy.
Also a build SBC 355 with a "Big" lift cam and (2) 500cfm Edelbrock carbs
and 4speed transmission. Have run this combo very hard and it will "Fry" the tires. Have never broken a thing in 5 years.I don't think its because I'm lucky !!!!!! These are good rears are cheap and can be found in most any salvage yard. The S-10 4X4 in my grandsons 38 chevy truck with a Built 355.600cfm Elderbrock carb and TH350 is from a 1999 S-10 Blazer.
It is a"Guv lock" 3:43 and will Fry slicks !!!!!! I may add that the later model S-10(1999 +) rears are Disc brakes also. To each his own. Hope this helps. TOM (Tired Old Man)

 

most of the 4x4s in Canada have the gov loc rears with either 3:42 or 3:73 rear from my limited experience looking at parts vehicles.
I have 3:73 GovLoc in my 52. good cheap rear. Good for 300hp at least.

 

You didn't mention your springs. Drill a 5/8 hole in the perch to slide the axle back 1.5" if using stock springs, and grab the shock mounts and u-bolts off the s10. You can use them.

I've heard if you swap leaf springs (front to back) it will center the axle. I used the drill a hole method. much faster for me.

 

4x4 rear is 4in wider than regular rearend i beleive i just wonder will the ring and pinion from s10 rear work in 4x4 rear?? any other way of finding out what gears i took the rear out of 4x4 but didnt check glove box
