Longfield 300M Dana 44/60 U-Joints

These Longfield 300M Dana 44 and 60 U-Joints now come with one grease fitting instead of 4, they are cross drilled which will give you more grease storage. We went with a high impact aluminum nickel bronze bushing. These are much better for high speed than standard bronze and will help prevent galling like our previous joints. These come with full circle c-clips. You are able to rebuild this joint. Just think now only 2 grease fittings instead of 8. Of course they are made in the USA, designed and built by Longfield and come with our lifetime warranty against breakage.

We are very happy with the field testing and the breakage test results from our new joints.

These are sold individually.
