ST Racing Concepts Heat Treated Carbon Steel "Big Bone" Universal Driveshaft Set (2)
I just came to post after seeing a really negative review on these. I have been using this set of CVDs on my basher blitz for over a year now with absolutely no issues. They have never came apart. They show almost no signs of wear. And to add, I am using this set with the slipper cranked down tight. They are handling the abuse well, even with a heavily boosted 6.5T motor! I am putting some SERIOUS power through these with great results.

Put in a good season running on these after too many problems trying to rely on stock dog bones and axles. They are stronger and more reliable and you won't have to worry about looking for a missing dog bone when the slotted ends of the axles snap or a ballcup pops loose. However they're not the perfect solution, they are only metal parts that will wear and break. I run mostly at an outdoor track more suited to 1/8 buggies and 1/5 gassers so abuse to a 2wd truck is expected but that's what I thought these were more intended for. Main problems shafts could be longer, I experienced they don't always stay in diff axle slots without adjusting camber more than you may want, and i did have two shafts shatter at the ball joint ends. I didn't loose any small parts much to my surprise but routine maintenance will solve that. Also during a recent tear down I found the tiny slip pins were horribly warped but far from broken! They are what they are, better than stock but time will take its toll, use with caution.

Don't waste your time or money! I noticed no change in performance or handleing. But i have had more breakdowns because of these drive axles. First 20 minutes one of the cv joint pins came loose and damaged the a-arm. And i lost the pin even though it was properly tightend and added glue to be certain. Had to buy a rebuild kit to repair. Recently had one come apart after a mellow crash with similar results plus damaged shaft. Allways checked them with every battery. Now back to stock shafts and problem free. Don't buy these!
