Introduction:

The CTM u-joints are currently being used in all types of off-roading and Rock Crawling sports by professionals all around the world. For example Lance from Pirate 4x4 runs a set in his Dana 44 front axle, Chris Durham (winner of ?00 Skyjacker Rock-Crawling Competition) runs them in his Tera60 front axle, and many others. Neither of which have been able to break a set of these incredibly strong u-joints. If your familiar with these competitors names you know these guys have heavy feet to say the least. 

I've personally seen Chris Durham grenade a Dana 60 U-joint into pieces which launched out of the vehicle about 50 feet away! I still have a piece of the shrapnel for proof. Another hardcore well known Rock-Crawler is Lance from Pirate4x4, he too has been known to explode 297x U-joints into a million pieces. See pictures below of Lance?s grenaded front axle and knuckle assembly. Notice the CTM U-Joint still in perfect condition just with one of the caps removed, With a new axle shaft that CTM U-Joint is ready for some more abuse. CTM Racing Products is so confident that you won't break one of these new u-joints they back them by a lifetime guarantee. So essentially these will be the last set of u-joints you'll ever have to buy again!

Installing the CTM U-joints wasn't any different than installing any other type of U-Joint. I took the liberty of installing a set of Warn Alloy shafts at the same time. The Warns shafts are much stronger than my factory shafts and also except the Full C-Clip design that CTM Racing supply's with the U-Joints.

Installation:

Installing the CTM?s was no different than installing any other axle u-joint. Actually it was easier because the bearing caps don?t have bearing at all so you don?t have to worry about dropping the caps and all the bearing falling out. 

See picture gallery for more details. In conjunction with the CTM U-joints I purchased a set of Warn alloy inner and outer shafts to go with the bomb proof CTM?s.  By the way, you don?t have to run Warn shafts with the CTM?s. They?ll fit in any set of axle shafts that are capable of accepting full C-Clips retainers. More installation pictures in the Picture Gallery.

Testing The CTM's Strength:

After installing the CTM U-Joints I was dying to go beat the heck out them and see if I could break them. For this test my Club and I headed over to some local Rock-Crawling trails in my backyard (the San Bernardino, Ca. mountains). 

At each rock garden we came across I took the hardest lines slamming the front axle as hard as I could attempting to break the CTM's.

Everytime with out failure the CTM's just kept going and going. I didn?t have one problem all day! In a couple of particular sections I guarantee any Spicer or other 297x u-joint would have exploded into shrapnel easily but the CTM?s weren?t even fazed!! I never thought I would be complaining about not being able to break.
