Ok cool thanks alot. This pretty easy to put on?
Define "easy" ?
You have to support the back of the vehicle, un-mount the leafs and axle (drive shaft), then clean up the leafs, put the flip kit on it, load up the axle over top the leafs on the flip kit, and re-install the leafs on the truck with the new shackles, connect the drive shaft and shocks with the new shock extenders.
There is no need for an alignment so once installed, you are good to drive the truck.
The initial dissassembly process can be a PITA depending on the state of the current suspension and level of rust you may have to deal with.
If you have some horizontal driveway surface (don't attempt this in a sloped driveway) 2 good jack stands, and a floor jack, that will get you started on lifting the truck for the job. Taking the bed off may make it easier but is really not necessary.
Then it is mostly a matter of a good set of socket and ratchet, and an impact can be helpfull but not mandatory. A breaker bar is also a good idea to have around, the longer the better. A torque ratchet is also not a bad idea but again not necessary.
The axles have an index key for everything to be put back together without special alignment tools.
I would say it is a 1 day job taking your time and making sure everything is back together appropriately. If you can get some help from a buddy that is also usually a good idea as the axle is kinda heavy.
Also the kit comes with detailed installation instruction and DJM has a good support service if need be.
More time consuming than difficult I would say depending on your mechanical comfort level.
Hope this helps and have fun.
