lots to assemble
You will recieve it in pieces ie, diff, housing, brake kit...Youll need to upgrade to a longer drive shaft (mine 55 3/8in) and use adjustable upper control arms to get the right pinion angle if you dont want to wipe out transmissions.Do not get disc's unless you want to ommit the emergency brake( they sell explorer drum brake kits) ; their GM metric disc's with emergancy brake are junk.Never could get them bleed and after buying a $15.00 sock GM metric caliper (they have them) each side bleed in 10 minutes.The mounting bracket for the rear brakes if going to disc requires grinding the bolt or housing down to get it in. Also ck to make sure your brake line from body to diff is a 3/8 -24 or a 7/16 - 20 if it's a 7/16 -20 youll have to mode the original line with adapters to the aftermarket steel braided lines they sell which are -4's.Takes time and definately alot of mock up.I believe eventhough more expensive the Currie is more user friendly. Think your cost of personal time and enjoyment. Cheaper is not always better unless you have the background in that.
