Chevy wheel cylinders--what year chevy and truck?
 

If I go somewhere other than NAPA what year chevy truck do I ask for when getting the better wheel cylinders?

Napa# 4637337

They don't need to know the truck and year, it just confuses them and you end up with the wrong parts.
The part number PJ gave is all they need.

What makes these cylinders better? I havent gotten to the rear brakes yet ,just tightened the shoes for now.

The cylinder bore itself is, I think, 30% larger than the stock Dodge units. That gives the system extra leverage on the shoes and translates into (for me, anyway) a firmer pedal and noticeably quicker and safer feeling stops.

Put that upgrade on my truck 3 weeks ago and it made quite a difference. then a week later I noticed oil on the driveway dripping from the drivers side front axle around the U-Joint :mad: Axle seal was shot :mad: :mad: Took it to my buddies shop and whatta you know my rotors and calipers are shot and the driversside is ceasing (tell me something I don't know!)...so needless to say now I've got crossdrilled rotors and some HUGH HiPo calipers with ceramic pads and you know what...my truck does something it never did before, it actually stops now and without that annoying squeal that accompanied the stock setup :rolleyes: go figure! [laugh] Almost sent me into the dash!! Hopefully I'll more than 25,000 on these rotors and more than 8,000 on the pads. The rear cylinder upgrade is well worth the money. I had to buy new pads as well the old ones were cracked. Both in the same spot!

I know the NAPA part numbers, but I dont shop at NAPA. I need the truck model and year.

There is a Mom & Pop parts shop right down the road and I can buy things there 25-50% less than at the big name parts stores.

The mom and pop place should be able to cross-reference a NAPA number, no? In any event, I asked for cylinders from a '94 3500 SRW 4x4 pickup. They used the same cylinders for ever and ever, so pick whatever model/options that strikes you:)

I just went on napaonline and typed in a few years for chevy trucks.

I found that 1995 chevy 3500 dual rear wheel 4x4 had the right part number.

Just make sure the part number has the 7337 number in it. That is part of the national part number. Kind of like a hollander number for a new parts store. I got bored on day and the same wheel cylander fit a dually from the 70's up to disc brake rears in the late 90's!

Dumb Question... Dodge has a TSB out that discusses this very same issue on our 3/4 Tons. It basically says if the truck is routinely operated at 75% of GVW or higher to replace the brakes with the cylinders for a 1 ton Dodge. So has anyone actually tried the 1 ton dodge cylinders or is just one of those deals where someone had some old chevy parts lying around and gave it a shot and it worked?

I thought that that TSB said to "disable" the proportioning valve??

TSB 05-04-98 addresses the ride height valve. I'll have to go back and dig for the new cylinder TSB number

Found it TSB 05-04-97

The chev cylinders are bigger than the ones that came out of my dually. I've got a pic of the difference in my gallery.
