My rears (1500) do not have the slot. It is " kind of" there but not really a knockout.


Of course, it is still a good idea of where to locate the adjuster.

 

Just to add some info on the upgrade part, I just put 1998 8800 gvw 2500 calipers in my 98 1500 4x4 and they work great.

 

I'm thinking about doing the 2500LD on my 99 1500. Can you give any advice on your upgrade? Did you have any issues arise? Do the 1500 pads and rotors fit on the 99 1500?

 

These are the parts I used on my '98 1500 brake upgrade.

Front Cyl 80mmØ from 2500LD (stock 1500 are 75mmØ) - AC Delco 18FR741 & 18FR742
Rear Cyl 28mmØ from 2500/3500HD (stock 1500 are 24mmØ) - AC Delco 18E112

Discs/Pads & Drums/Shoes are stock 1500.

If you want more braking in the rear, use the GM3500 cyl 30mmØ - NAPA #37337

All these parts are direct bolt up, no mods needed.

 

Yup, I used the stock 2500 calipers with 1500 pads in front, 1500 pads with 2500 cylinders in rear. No mods needed. With no load in the truck, the rear seems to lock up easier (duh, of course) even before the rear abs kicks in.

 

That's why I stopped with the RAM2500/3500 cyl... I don't often carry a lot of weight.
If I had a LB and carried heavier loads regularly, I might have been tempted to use the GM3500 cyl.

 

I did the same upgrade as Adukart, works great! Only difference is I went with 2500 pads in the front.

 

Do you use the same 1500 rotors as well? How long was the job to switch them over? Is autozones product a decent product?

 

You have to use the 1500 rotors (5 stud).

 

^X2. Yes.
