replaced oem parts perfectly seems to be best quality and at good prices

Placed these on front loader of l2800 Kubota tractor with the help of my mechanic friend. They have been working great since then.

Fitment was good and parts appear to be equal quality of OEM parts. Piston rings are separate and taped to prevent confusion for less experienced mechanics doing at home. If their longevity compares to factory parts… great buy.Be sure to get the tool to twist wiper seal if you don’t have experience , makes it a lot easier

Very durable and installed easily

The exact seal kit but half the price, every seal you need to fix a leaky hydraulic cylinder, I have about an hour on the two cylinders I fixed with no issues.

My husband ordered these to complete a job where he only needed the o rings. He had to buy a full rebuild kit with stuff he didn’t need here in town. This o ring kit worked perfectly & he was able to complete the job without having unnecessary parts left over! Great value.

This kit was exactly what I needed for my 2006 Kubota L3400 front end loader bucket cylinder. The parts seem to be of good quality and they installed easily enough. I’ve used it a handful of times since the rebuild and there has been no leaking. And the price was WAY better than buying from Kubota.
