2002 tahoe leveling kit/ alternator

[02tahoez71]

Ive got and 02 tahoe z71 and im planing on doing a rough counrty lift kit for it, and it all seams easy except for the torsion bar tool, is there a way to do it without buying the 75 dollar tool? And then my second issue is i have ls1 fans and im planing to run subs soon, but alternator is haveing a hard time keeping up now, whats the biggest safe size alternator i can run?
Thanks guys!

On the torsion bar thing, I've heard of using a big "c" clamp or even bottle jacks. How much would a local shop charge you? Them torsion bars are under a lot of pressure. I cant believe it would cost more than an hour of labor to get a shop to do the key install. On the alternator, I believe 140 amps is the biggest, IIRC.
