RV Chassis Parts Xref P Series

As many of you RV'ers know all OEMs have their own Part Numbering system even though most of the parts are available from a GM dealer, other OEM sor from a auto parts house. So, if you have purchased any parts from any other source other than the RV manufacturer and have the OEM part number and description please leave me an EMAIL with the information and I will add to this section.

Note - This cross reference file is a collection of parts numbers supplied by the members of IRV2 and myself. The OEM numbers have been added for reference and may vary as I have seen multiple parts numbers for the same part.

I have added links to my photos of the various parts referenced here. So, if you want to see a photo of the part in question just click on the highlighted part and it will open a new tab or window.

Any updates or corrections please Email me.

4150844
Raybestos 7/16 Bleeder Screw
 
Be aware that there are 2 different calipers used on the P32. About 90%+ use the 4152828 66mm caliper for the front/rear or left/right for years 1985 to 2003 uses a 10 mm bleeder screw. But, we have found a few that use the 4150844 70mm caliper on the rear. This caliper uses a 7/16 bleeder screw. It just so happens to be the same as the one used on the W22.

So, check your caliper casting numbers before you order. Not sure what to look for? Look at the P32 caliper specs Caliper Specs
