Alloy USA's New X-Joint

Alloy USA said:

here's some info:

First, we feel the cold forged 760x is a vast improvement over the hot forged297x in both strength and durability - very good all around u-joint. Having said that, we thought we could improve the design even more.

We worked over two years to perfect the cold forge process - very difficult, but yields great strength improvements in grain structure over hot forging.

We use an 8620 material - same as most ring and pinion gears (we do modify it slightly for the cold forging process). This gives good strength and as importantly high surface hardness for durability - this also allows us to use high strength needle bearings as the trunions are resistant to brinelling.

Finally, we added servicability - while the OE standard for lifetime lubrication may be met by the stock joint - we feel the harsher conditions most of us put our Jeeps through warrant the ability to grease the u-joint.

Are these the "strongest" u-joints on the planet - no. We aimed for the toughest most durable bearing type joint we could make for a reasonable price.

Hope that helps,

Ron
