2017 GMC Sierra 4x4 5.3 V8 Regular cab with 7inch Rough Country full front strut lift (no spacers) replacement upper control arms, 35 inch Ridge Grapplers on 18’s.... rides very nice and great quality , I do believe issues arise with any lift when installation is not done with attention to detail... rough country has been around for decades and is only growing.... it makes no sense for a shop to sell and install a product if the customer is going to be constantly bringing there vehicle back to them with issues. The right installer is key.

Ok what a difference ... no chopper sound anymore , I left the resonator off so with that and my airaid MIT with a K&n drop in filter is good enough for me.. still has that rumble at WOT but no V4 chopper drone.. it’s all a matter of what your willing to live with ...gm performance borla (dealer item) includes the flapper on its muffler , so it’s there for a reason... but pricy$$$

I recently swapped my stock muffler (flapper included) with a magnaflow muffler I purchased at pep Boys for under $90... I’m literally at the muffler shop reinstalling my factory one back on... don’t get me wrong the magnaflow sounded great until it went into V4 mode... I could not take it anymore that helicopter sound was so unsatisfying... so I’ll wait till I can get the gm performance borla cat back..

35/12.50 on 18x9 +18 Nitto ridge Grapplers .. 3inch level up front 2 inch out back.. zip tied in liners and not rubbing ... well until you flex it out which is rare..

I have a 3 inch up front and 2 inch in the rear (leveling kit) .. running 18x9 +18’s and 35/12.50/18’s Nitto ridge Grapplers only rubs when full turning out of incline drive way. May do a NorCal Mod.

I had preivioisly done this modification to my 2008 Z71, once it’s all done you gain 2 1/2 inches of clearance ... don’t feel like dropping $2500 or so on a lift.. down the road i may switch to a 4 1/2 zone lift . But I’m not kidding when I say on normal city driving I have zero rubbing.. but once the suspension droops it will hit ... the NorCal mod should eliminate that though
