🔧 GEARWRENCH 2321W: Wide Oil Filter Wrench for 4-3/8" to 5-1/4" Filters – Heavy-Duty and Reliable Review

Not used yet. Many different filter keys have been tried over the years. This seems to be well made. It matches my oil filter on my Cummins ISX which is why I bought it. Would buy again.

Works great with large filters - handles our tractor filters with ease. I stuck screwdrivers in to unscrew them; It's a much nicer and easier method, and well worth the few dollars it costs.

I have a Cummins ISL engine in a Class A van and have almost no access to the oil filter. There's not enough room for a hand, let alone leverage. Forget the usual filter key. With a socket wrench and a long extension, this wrench removes the filter with ease!

We had an old Cummins L10 in a car with two filters. Access was ok but nothing on the sides, had to go from below. One filter was very narrow and there was no way to pry it through with a screwdriver or put large channel blockers on it. This key was able to get the job done. The filters are 4.6 inches in diameter, the 2321W fits in with plenty of room. If I had to do it again I would try the smaller 2320W.

Removing the hydraulic filter from a John Deere tractor. After trying 3 different keys to remove the filter and breaking 2 of them I found a link to this key. After reading reviews of how well this wrench works, I realized this is my last resort before using an old filter screwdriver. This thing worked like a champ when it was on the filter, it took about a minute for the filter to completely shut off. The job seemed extremely easy. I highly recommend this tool to anyone having trouble removing
