Looks good, but its definitely not worth an extra 10k. Looks like it is just a strut extension and new upper control arms. The kit costs somewhere around $500-600. Wheels and tires probably no more than 3k. The "liftshield" warranty is pretty much nothing. A leveling kit doesn't void any part of the warranty. IF something fails, they have to be able to prove it was a direct result of the modification. IF, that happens, then ProComp would come in and cover it since they warranty their parts and damages that occur as a result as long as it was properly installed and no signs of abuse.
I installed my leveling kit myself from Readylift. $600 after taxes and shipping. $100 for an alignment. After wheels and tires total cost was still under $3k.
Even if you can't do it yourself, a shop won't charge anymore than maybe $300-400 bucks for the install.
