Seal kit received was as ordered and fitment was as claimed. Might order more just to keep around as I know people that have a small fleet of log splitters with this size cylinder.

This was exactly what I needed to fix my log splitter. The seals fit perfectly and seems to be good quality. It took me about 45 minutes start yo finish and I was back to work. Check your cylinder and bore size.

Replacing gaskets on a 15yr old splitter, if 15yrs is how long they last, then a 2 pack will last me 30yrs! Okay! Purchased and they look spot on. I'll be back to finish this review AFTER I replace the old. TO BE CONT...Contiued: took longer than 45 minutes to replace, all went on well, although 4 extra gaskets in one of the kits is cool by me, free gaskets! Ran splitter after repalce/repair and nothing leaks. These are exactl1 to 1 exact replacements. Ya'll be good, be Kind and stay Awesome.

I ordered this seal kit because my cylinder had started blowing hyd fluid out of the front..Once I pulled the ram out of the cylinder housing , it was a walk in the park to change ALL of the seals.. Including cleaning the ram , it took maybe 30-40 minutes to change all of them..It's almost impossible to mess this up. Each seal fits a specific slot , both internal and external seals....You will need a pick or a small flathead screwdriver to pull the old seals out of thier groves.. When I tested/used it as soon and I put it back together..zero leaks and BONUS : I did not have to remove the unit from the log splitter to remove the ram , so all hoses stayed in tact. I used a sm log to hold up the cylinder housing on an angle ..
