Engine/Transmission (1998.5 - 2002) wheel cylinder 1/16 inch

[rrab1]

has any one installed the larger wheel cylinder off of a 3500 onto a 2500? Don't want to do the chevy because of thread differance, I see that the line on the 3500 comes straight out the back of the cylinder and the 2500 is off set to the side, can the lines be (tweaked) just alittle to make the larger cylinder to work Thank's Don

I did it a few years ago. Mine were a direct bolt-in. Unsure about about your truck.



From Sam Peterson:



" Stock specs for wheel cylinder size is easy to remember===13x2 1/2 uses cylinder size 1 1/16----13x3 1/2 uses cyl size 1 1/8. The upgrade to the larger cylinder won't be any problem unless the rear tires don't grip well in the rain. At higher speeds the antilock should keep the tires from sliding. If a different prop valve was used the larger cylinder would be of no advantage. The idea is to increase rear brake pressure.



According to this chart, your truck should have 1" or 3500 wheel cylinders as OEM.

The Chevy 1 ton wheel cylinders are a direct bolt on. Thanks Steve B.

If you are referring to model year 2000 (like your signature) Ram 2500's & Ram 3500's be aware that the brakes are identical on both: http://dodgeram.org/tech/specs/brakespecs.htm

Both three-quarter and one ton Rams used one inch rear cylinders.

Frank helped me change to the Chevy cylinders on my 96, 2500. HUGE difference. Direct replacement.

I'm just curious what all has to come off in order to change the cylinders.

I thought about using the chevy for mine, but I just used 3500 ones for mine. They were like $3 cheaper than the 2500 also. This was for a 1994 rear. Sounds like the 2000+ use the same for the 2500 and 3500

I'm just curious what all has to come off in order to change the cylinders.

Just the two springs that clamp the shoes against the cylinder. Then two bolts that hold the cylinder in place, out she comes. The new cylinders are a direct fit replacement, no modifying needed. They're slightly larger in diameter.



The PIA of the whole thing is getting the drums off & the springs. The springs are a PIA on every drum brake I've worked on, even with the tool. The brake lines come off easy as do the two bolts.



That difference in size really makes a difference. I was surprised. No doubt I'll notice it towing, big time.
