What all has to be done to install a BB lift on my 2001 Grand Cherokee?

RIZ

 

If it's anything like a zj, take wheel off, unhook your sway unhook you shock jack up other side of axle so the side your working on puts the least amount of pressure on the spring. Take spring compressor, pull spring out. Take bump stop off. Put booster on. Might be tight, I took like a three inch pipe and a jack, put pipe against booster use the jack to push up the booster. Put bump stop back on. Put spring back in, will be tighter fit. May take some elbow grease. Jack the other side back down, hook sway and shock back up put wheel back on. Repeat three more times. That's how I did it. It's gets faster once you do the first one.

 

If I install a BB lift would I need longer shocks? Some say if no off roading is done then no.......Can I get longer Sensa-trac shocks? If so, does anybody know which shock is longer?

the general consensus is no... but i think it depends on the condition of your shocks and if they are preloaded or not. i seen that some 2 inch bb come with longer shocks. once i finally do my bb, i'm going to go ahead and get longer shocks, but you should be just fine without them.

 

I threw a 2in bb on my 2001 wj (grand Cherokee)
Pretty much it went like this
Jack up by lift points on frame rails
Let that axel Hang (tiers off) be sure to have a support in the front of sum sort
Disconnect the seat bar
Take the bottom bolts off the shocks to let axle hang free
Take the jack and raise the axle till the body is just off the jack stands on the frame rail
Put the spring compressors on the spring pretty easy to get there 20$ at harbor freight
Drop the axle down with the spring compressed about an inch
Pull spring
Put puck in place but don't forget the bump stops you'll have to get them out some how it's a mirical if you do I pryed a screw driver in the boot and used a clamp and pulled helps to soak in wd40
Take the boots out and put the spacer in and boot back in
Position the old bump stop in place and jack axle up with out springs in place to push the bumps in place
Put springs in place and connect everything back up in the front
Simmilar procces for the back just no bump stop boots to remove
Iron rock offroad.com has the best parts list for the wj and the best customer service I've delt with alot of other companies trust me they'll talk to you and help out
170$ for the full kit from them not including shocks
2 inch longer shocks are recommended because the stock ones knock alot
But I'm still running stock size and offroad just fine
