Today were going to review part #9103309. This is a Redline Oil Seal. This oil seal is designed for 8,000 pound Hayes axles. It is a double lip, double case seal. It has an outside or overall dimension of 3.376 and an internal or inner dimension of 2.250. This oil seal, you can go to the product page for this part number, and theyll list a seal cross-reference chart, and what that will do is list the different brands that make oil seals and the part numbers for those specific brands.
What you can do is look on that chart, and if you have a different brand of oil seal and its listed there on this page, that would mean this oil seal would work in place of it. That should do it for review on part #9103309. .

Bought new axel parts and brakes bigger wheels for my boat trailer. My existing axel was 20 years old and never was adequate for the weight it hauled causing wheel bearings to wear out and the chance of loosing a wheel. This was the most economical way to repair as a new trailer was so expensive. All the parts I needed were available and went together beautifully. Very happy with etrailer, this is not the first time I have ordered from them great option for any parts you need.
Very good seal. The only time we've had to replace them is when a bearing was overloaded and overheated the hub, resulting in overpressurization and seal blowout. Otherwise, I've got a 26K trailer running 6 of these over the past 10K miles with no issues.
I have received several different orders from trailer in the last couple weeks. Everything from a B&W fifth wheel hitch to trailer brake assemblies and lastly, axle seals. Everything received was very professional with excellent helpful service when help was requested. The seals that I just bought were exactly half price from what they would cost from a local vendor. Outstanding products as well as service!!!
I’m very happy with everything I purchased from etrailer. Everything was correct and fit perfectly. I’m very impressed with the service and their professionalism and knowledge of what they sell. I will definitely be ordering from them again.
I haven't has a chance to install them yet, but looking at the product it appears to be high quality. The customer service was excellent. My only complaint was the shipping time and costs, also product had a delay in transit. This caused me to not be able to work on the trailer as planned. Over all great to deal with company... Thanks for the help.
Great seals, used for a grease to oil-bath hub conversion. 5,000 miles and not a hint of any leaks.
Exact replacement for my Four Winns boat trailer.
Purchased oil seal- 9103309 for a spare part for my fifth wheel. Great Customer Service....
These seals are a little more expensive but do a good job of keeping grease in the bearings and out of the brakes.
All parts ordered were of excellent quality, Thanks!
