Traded my TL for this 2016 Sierra SLT. Just tint, exhaust, and swap cargo/license plate lights tomorrow so far. Hoping to get a RC 5" lift with tires and keep stock rims for a little bit. Going to replace my old Yankee cover with the attached one.

Thanks everyone. Loving it so far. Is it worth it to get the RC 3.5" or just go with the 5"

That's all personal preference and depends on how much $$$ you wanna spend, what your goals are, what you will be using the truck for. I just have mine leveled w/ bilstein 5100's and added 1" more to the rear block to keep a little rake and plan on also swapping factory tires for 275/60 or 275/65r20 - which will add an additional .5-1" overall height making the truck sit 2.7-3.2" higher than factory in front (bilsteins raised it 2.2" by my measurements)

 

As you go higher in lift there are other things that need attention - 3.5" you'll wind up w/ some issues w/ your ball joints over time, 5" absolutely, so would have to account for that w/ new control arms, the higher you go the less aerodynamic the truck gets killing MPG's & hurting acceleration @ highway speeds, then obviously you'll be going bigger and heavier w/ your wheel/tire setup to match the lift, 5" lift w/ something like 35" tires results in anywhere from 30-50+ lbs of unsprung weight to each corner - so you will hurt the performance/acceleration as a result (in addition to legit MPG drop), and it WILL be noticeable, but if you're gonna be mudding, real off-roading/tracking/hunting, driving beach dunes etc. then that's a worthy compromise. Then many guys get sick of the more sluggish acceleration & end up tuning, swapping gears, adding headers, etc etc - so that's why I said, depends on what YOUR goals are.

 

Basically bigger you go the more things you also have to consider. If you have the 5.3 - while a perfectly suitable powertrain for any 1/2 ton - the power robbing effects of lifting the truck will be more apparent.

3.5" requires notching of the cross member. I'd honestly look towards other brands, I haven't been overly pleased with RC and the ride quality after the fact. Can't speak to much else besides Fabtech and BDS which I have nothing bad to say!

Thanks for the great info. I'll be 100% honest, it will be on pavement the majority of the time. I just wanted a nice lift without getting too high with a 6+. I've been looking at McGaughy's 4"
