2nd Gen Non-Engine/Transmission 3500 Drums On A 2500 Truck

[JBoone]

HAS ANYONE PUT 3500 BRAKE DRUMS ON A 2500 4x4 (1995)? DO YOU NEED TO CHANGE THE PADS? ARE THE 3500 DRUMS THE SAME DIAMETER AS THE 2500 DRUMS? THANKS FOR THE HELP.

 

[WadePatton]

yes

That is the difference between a 3500 and 2500, one inch wider drums--well that and two wheels.



One inch wider drums and one inch wider shoes. That's the way I unnerstand it.

This may be a bit off-topic and something you already know, but many members have put 3500 wheel cylinders in their 2500 brake drums. They were different parts up until some point, which I've forgotten, but a '95 has the smaller cylinders. The idea being bigger cylinders pushing more fluid should equal more force. I noticed some improvement with this upgrade.



Just a friendly heads-up: posting in all caps is considered yelling. Some folks consider it rude, I don't.

According to your signature, you have a 2500 automatic. Therefore, don't you have a Dana 70 rear axle? All 3500's use the Dana 80. Are backing plates interchangeable between these axles?

Same drum & same backing plates on all model year 2000 2500's and 3500's. I don't know about JBoone's 1995.

So pads and drums for a 1995 3500 are all I need?

That's quite a leap from what I posted. My information about the model year 2000 Rams is from the model year 2000 parts catalog. This page on the Dave Fritz site has a bit of information on brake sizes but I don't see anything more than Wade or I posted. The Fritz page has the larger cylinders showing up on the rear wheels of 2500's in 1997.
