With 52" front springs? I'm goin with 52" Tough Country 2" Lift springs in the front, I have an Arizona Drivelines "Bad Boy Jr" front Driveshaft that the P/O put on to compensate for 12" of supsension lift. It has a bad CV joint, and A/D is showing their wonderful customer service by not providing warranty on it like they told the P/O they would. The shaft splines slip about 4" from full compression to full extension (before it hits the limiting collar). Is this enough with the new-found flex I'll have w/ the 52's, or should I look into getting a whole new long-slip high-angle CV Shaft instead of just a new high-angle CV Joint to put on this A/D Shaft?
