Default Rear End U joints

Just finished exchanging a Dana 36 for a 44. In the tear down we notice I needed to replace all of the u-joints in the rear. I need to go heavy duty, and was wondering if any here has a recommendation for the u joints on the rear. Brand name etc.

Thanks in advance

Spicer, Precision, Vintage TRW solid trunnion racing U-joints.

Has been a very hot topic on C4 tech lately U-joints for some reason.

You likely wont find those TRW's.

Still on my TA nearly 20 years later.
Front & rear driveshaft safety loops never had to catch that driveshaft spinning at 7K RPM's + yet with u-joints letting go.

Precision is good if you want to try them.

Just replaced all 4 of mine in the back a few days ago. I went with PRECISION Part # 231 U Joint - Non-Greaseable Super-Strength. Bout 14 bucks per piece. Came with all new clips and everything. Lets see how long they hold up behind my new 396
