TS are good people. And 300 bucks with warranty is a pretty good deal. I just prefer to turn my own wrenches if I can. But I don't warranty crap. haha I'm probably going to have TS to a once over on my suspension to make sure it's all tight. Never hurts to double check.

It's not bad bro. I've changed my suspension 5 times now. If I don't have any battery failure on my impact (like I did last night) changing struts, shock and springs can be done in an hour.

I just got my shocks/struts, springs and phb.
The springs are already mounted in the struts...
Any idea how hard is to replace everything?
What tools are needed?

Thanks!

Pretty straightforward, took me the better part of a day, but a fair bit of effort was taking springs off and onto the struts. Premounted would save a goodly amount of time. Check out the install instructions and/or videos over at americanmuscle.com

Really just:
jack and stands
metric sockets
torque wrench
tape, string, weights (plumb-bob), and measuring tape for aligning the rearend.

Impacts make it go a lot faster.

Very easy. Impact, sockets, spring compressor, jack, jack stands and a couple of beers

Beers. The best tool imo

OP, I'm in Irving as well, if you need help let me know.
