I work about 1/2 mile from the Bilstein headquarters in Poway, CA and the other day at lunch I knocked on their door and one of the engineers invited me in to discuss the shocks. He said the 4600 are exactly the same shocks as the 5100 but 5100 are adjustable to work with trucks that are lifted. He said that since I just wanted to use my truck for towing and if I didn't think I would want to lift it later, then save the money and go with the 4600. Which I did and love them.
I have a 2015 Sierra LT 2WD with the Max tow package with 43K and bought it used with 38K, so don't know it's history. I pull an Airstream 27FB and the shocks were so shot I couldn't dial in the weight distribution hitch. Put 4600 on it last week with 10 ply tires and the change is like night and day. This is not my daily driver though and my intention was to make it more like a 2500, but I couldn't be happier with the results. Took it out on a 80 mile test ride over the roads that use to give me fits and it solved all my issues. The ten ply Michelin defender tires ride great but not for a daily driver.
I ordered the complete actuator and picking it up today, but I saw some videos for replacing the motor and it looks doable. I wish someone would have made a video of the 20115 actuator replacement. Plenty of the 2007 to 2014 but I couldn't find any for the 2015 Silverado / Sierra model. Anyone know of one please post the link. Like to think I'm pretty savy about searching for stuff but I have come up with bupkis.
Hey guys, I just installed my tow mirrors as well. Seems like the top one is set close to the side as mentioned. But the bottom one seemed like it needed to be up a bit to cover the blind spot. But now I'll have to check and see if my rear tire is visible. Thanks for the expert advice, I do like backing into parking spots rather than putting the bed of the truck into traffic before you can even turn your wheel.
I'm having the same problem, intermittent issue with the actuator on passenger side door lock.. Anyone deal with and resolve this? Almost seems like it just needs some lubrication or something, because you see it jump sometimes when you hit the unlock button on the fob.
The screen quality is good, my only complaint is not having the guidelines. The veiw of the hitch ball is fantastic and it's easy to line up with the trailer. Backing up in a parking lot, it will show if someone is right behind you. But not really how close you are to other obstacles. Other than the two solid weeks towing up and down the West coast, I don't drive it much. Hopefully with time I'll get a feel for it. Still just getting used to the 1/2 ton pickup.
Yep I made them send me the a pic of the rpo codes from the glove box. NHT code is the code for the Max Trailering Package. And the GT4 code is the code for 3:73 axle ratios.
That's what I was thinking too, but I did see where one guy added timbrens, but I don't remember if he had the Max Tow Package. The bounciness does make me wonder if the previous owner tuned down the Max Tow Package.
