Installed the 2" lift kit bilstein 6112 shocks and springs on my otherwise factory 2015 gmc sierra crew cab 6.2 SLT.
Kit number was 47-273702 and included both front shocks, springs, mounting cups/hardware etc. I put a set of 5160 rears on it.
These showed up and wow! Shocks are huge diameter almost 3". Giant pushrods. Everything looked extremely stout, bigger and equal quality to the $2k+ set of fox I put on my last cummins.
Installation went smooth, no hangups although I am surprised at how fast GMs rust given the truck is 4 years old.
I've driven 800 miles so far so presumably everything has settled nicely. The top setting (4 adjustments) gave me 1.8-2" of lift, which makes the truck appear level in stock form. Ride is VERY controlled, does not feel stiff to me at all, but the bounce and rock from the stock ranchos is now completely gone. Quite fun hitting speedbumps and joints quick, the truck just absorbs the hit and there is no jounce or jar. Very stable. I would even venture to say the ride soaks hits better than the 2.5 fox setup, although this truck is lighter and independent front so never a fair comparison. Overall just wanted to post this up since I did not see many reviews for this product related to GM trucks, so I was a bit weary on the initial purchase!
