What will you do about the pittman arm? The brake flex lines won’t reach. And the drive shaft angles will cause the U-joints to fail even in normal driving and in hard mud driving they will leave you stranded quite often. I have dropped and scrapped a great many lift kits from 4x4s when the owners gave up on getting all the bugs worked out. ---

As mentioned by Rod Knox above, the drive shaft angle is a critical consideration. U-joints aren’t like CV joints, which can work well at extreme angles. U-joints have limited angle tolerance. Too extreme of an angle will cause u-joint failure and worse than that, vibrations. Recommend to know in advance how much the DS angle will change & if this will prove a problem. ---

Do yourself a big favor and leave it alone… ---

Why do you need a lift? Are you going off road? Or do you you just want to look tough? Nothing wrong with that, I guess. ---

I agree with the the majority here and will also advise you to leave the suspension alone. Years ago…I decided to add 12 inch shackles to my '57 Chevy Belair. I spent an entire Saturday morning installing them so I could have the car ready for my date that night. When I pulled into the driveway…my girlfriend’s dad laughed at them and walked away. My girlfriend took one look at them and remarked “It’s silly.” I went home after the date and worked well into the early morning removing them. I sold the shackles on Monday to a guy who didn’t have any more sense than I did when I bought them. Live and learn. ---

Oh yes.you are better off leaving well enough alone,you can buy pittman arms that allow for the different angle,but;(whynot just up the tire size one or two sizes and try that out?)-Kevin ---

I can onlt add my agreement to what everyone else has said. Rod and George have described my reasons perfectly. Missileman’s story was great also…and I thank you, missileman, for the laugh.
