Like many others, i've been disappointed with the magnetic ride control crap design that GM used back in this timeframe. I've got 125k on my truck and it's riding like a wooden-wheel wagon (according to my wife... but I agree). I had the front struts changed out under warranty around 55k - they were leaking & it rode like crap. Those reached their end of life last year around 100k - and I couldn't swallow the quote from the dealer. I bought a pair of Dorman (part# 949-730) shock/strut & coil over assemblies and used those for replacement - as they were supposed to be OEM-type replacement for MRC. Ride quality was OK, but didn't seem to be as good as the AC Delco's. Well, they only lasted about a year and seals seem to have blown on both sides - and the rough ride returned. I'm thinking of buying this Strutmaster magnetic ride control shock/strut replacement kit. Has anyone heard anything about these? https://www.strutmasters.com/products/2014-2018-gmc-sierra-1500-magnetic-struts-4-wheel-oe-replacement-kit-gc114f?zCountry=US

Thanks for input. I haven't moved on this yet, but seems like i did hear in some post that IF you listen to XM/satellite radio, that it is somehow affected by using the PAC AmpPro interface? They said that it goes to a "mono" sound? That was a little concerning to me since I probably spend 50% of my time listening to XM stations. Have you noticed anything like that, if you use satellite radio? Thanks!

Thanks. I was thinking of doing the same thing... by replacing some of the speakers with similar impedance as an initial step, just to see if i could tell a difference in sound quality by still using the factory HU & bose amp.

While the Bose sound system in my 2015 Sierra Denali is pretty decent for a factory system, I've been trying to determine what options i have to improve. Based upon what i've read in the forums, the bose speakers use an odd impedance, so replacing with aftermarket options will likely not produce great results. Has anyone used the PAC AmpPro (AP4-GM61) aftermarket amp interface to add an amp? Sounds like that would allow me to keep all the factory bells/whistles but also add a new amp (or amps) if i wanted to upgrade the sub speaker below the center console. I assume that would also allow me to add an amp & replace the door/dash speakers with something of better quality? Thanks!

Ok. Sent you a message.

you still have this Amppro AP4 for sale?
