Dodge truck Cartridge Lube Sock Filter - Page 2

This wording and the numbers didn't mean anything to the man at the parts counter in the local NAPA store. However, he was able to specify and order the NAPA No. 1011 filter. It had a suggested retail price of $18.90. Getting the filter was just a matter of paying for it, but trying to fit it into the canister was a lot harder job. We pushed it pretty far down into the canister, but there was still over a half inch of filter showing above the rim and it wasn't going to go in any further.

This photo shows the basic design of the Wix 51011/NAPA 1011 filters in both end view and side view. During a parts consolidation effort, a slightly taller and wider sock filter was released that is difficult or impossible to install.

According to the NAPA Website, the No. 1011 filter has the following specifications and dimensions, which are also the same for a Wix 51011 filter. Apparently, the two are the same except for the brand name on the packaging.

A problem arises in that the Wix and NAPA filters are slightly larger than the original-style Mopar JC series filter. This shows up clearly in the specifications and dimensions for a third oil filter that's available — the Baldwin JC405. Note that the JC prefix is the same one used on the original Mopar part.

Specifications for the Wix 51011/NAPA 1011 filters show an outside filter diameter of 4.063 inches, while the Baldwin JC405 lists an even 4.00 inch diameter. Todd Wilson took this photo showing a 4.50 inch canister opening. This suggests that all the filters fit as far as outside diameter goes.

Specifications for the Wix 51011/NAPA 1011 filters show a height of 5.562 inches while the Baldwin JC405 calls this the length measurement and shows it to be 5.25 inches. Todd Wilson took this photo showing an approximate 5.75 inch high canister opening.  However, the taller filters are a tight or impossible fit so the shape of the canister opening must be a factor as well.
