Badger What do you want to know? Stock rear end will hold about 450-475 HP with the 27 spline stub shafts. After this you start to twist the stubs in the carrier. 2.88 carrier is the weakest carrier of the Jag rears. Higher the gear ratio the better the carrier. There are 4 carriers. For my car, I got the CWI 30 spline stub shaft kit, installed a locker and everything else is chromemoly tubing. The other thing a added was an LPW rear cover for the diff to add pressure to the carrier caps. It's a support cover. This will stop cap walk. With all my up grades the rearend is good for 600/600 HP and torque. I limit the dragracing, way too hard on this rearend. I only rev the motor to about 1,400 and leave. NO SLICKS. A watts linkage is another good kit to add to the Jag rearend. Decooney here on CC has pictures and designed it for ERA cars. Great responce to it. It stops rearend from rolling over. Again it's about putting the right parts togeather. The most important thing, IMO is shocks and springs for the rearend and wheel alignment. Wheel alignment is a biggie. I spent 3 1/2 hours seting up my car on a alignment machine, Camber, front and rear, Caster, and real important, front and rear toe. Thrust angle is also needed. You can ONLY do this after ride hieght is setup with your body wieght in the drivers seat to start. If you are adding someone else on the pass side this all changes. You need to find some one with scales for this setting up of the car. You wouldn't believe the different with before and after. Alignment is next, Video the car taking off, and then start on the springs and shocks. Rick L.
