I currently have a 95 S10 Blazer with the drum brakes in the rear. I want to install disc brakes. What years would bolt up and is there and fabrication needed. Also I don't Kno how to tell my gear ratio in front or rear end. I cannot look it in in the RPO as the dash had been replaced before I bought the Blazer.

 

98 and newer are disc brake. Make sure you get one from a 4x4 if yours is 4wd, a 2wd if you have a 2wd, or a zr2 if yours is zr2(Idk if they had those in 95, or if 96 was the first year)

Those 3 axles have different widths, but as long as you get the corresponding axle and proper gear ratio it will be correct...I also reccomend looking for one with the g80 gov-locker

You can decode your vin on a number of websites for a small fee. This will give you all your rpo codes and their meanings.

 

I was hoping to get one that was 2 or 3 inch wider than the original rear end so the rear end in the front end would be the same with cuz I know the front end is two and a half or 3 inch wider then the rear end is and mine is 4 wheel drive

 

Get one from a zr2 then

 

Or just use wheel spacers.

 

I just ordered 1.25" hubcentric spacers for my rear wheels the other day. Pics to come..

 

it is my understanding that the wheels are further apart on the front axle to give the vehicle a separate track in a mud hole...
i dont know how to find that out for sure, perhaps old wives tale, but ive heard that all my life

 

I always figured the front just needed to be a little wider so the wheels have enough clearance when they turn, and the control arms can be long enough for good suspension geometry.
