There was a pretty good discussion on this awhile back. Non-greasable Spicers. The only way to fly! Also with the 30 it is possible to grind on the inside of the yoke ears to accomidate a full circle retaining ring. This will help by getting rid of those pesky half circle ones that always seem to work thier way off at the most inappropriate times, and shortly there after BOOM!!! Mr. Trunion is broken! I think JEEPN gave the details last time we discussed this.
where can I get them for my D44s? Summitt. Do they have a part number, I am looking at putting new ujoints in next weekend, but if I can get super strong ones, then I will order them and wait a week or so for delivery.
The non greasable Spicers are the unquestionable leader in strength tests time and time again. The greasable spicers and the Brute strength are fairly similar in strength. Jesse Jaynes from High Angle drive line may chime in on a post like this and give some more info. But you cant go wrong with the Non Grease Spicers.
The non-greasable DANA/SPICER type are the only way to fly. I'm assuming that everyone is also talking about the 297X in the front application. If you keep the stock weenie u-joint I'm sure it could be made from Martian titanium and still break due it's smaller size. The upgrade to axle shafts that will accept the 297x is definitely an improvement in sheer mass. Not bullet-proof, but alot stronger.
