Selling a brand new set of Baja Kits boxed upper control arms. I sold my 2016 1500 for a Duramax so these never got put on my truck. They are $899 brand new, im asking $700 spilt the shipping. They fit 14-18 silverado / sierra 1500 with factory aluminum upper control arms, and fit 16-18 silverado 1500 with factory stamped steel upper control arms. NEED GONE!!!!!
I've got a 2014 GMC Sierra L83 single cab... I recently decided its time I start getting some performance out of my truck.
L86 Thottle body and intake manifold
1 7/8 header + full 3 inch exhaust (magnaflow muffler)
Stage 2 GPI cam kit + DOD Delete
Transmission Oil cooler
I had the car dyno tuned and everything went perfect. We later had a few trial runs on the street and hit issues with sort of a misfire at specific rpms and gears... 2nd gear at 4,200ish rpm it would have a slight nudge and again at 5,200ish another drop and kick. It would happen almost all the time.
We thought it would be the spark plug cables, went and got MSD plug cables added those, tried again, same thing! Spark plugs are new, fuel injectors are serviced with zero issues... the car ran perfectly before we did all of this...
The tuner now tried raising the oil pressure in the transmission thinking its a gear slippage due to the oil pressure. Tried again, same thing!! We've ruled out alot of the problems, now theyre saying that its the disc thats slipping in the transmission which would make sense but I want to get ideas as I'm spending money trying to fix the issues that we're not a 100% sure about. Can you guys let me know if anyone went through anything remotely similar or if you have any views on the matter.
My buddy just got a 2017 Sierra SLT Z71 after his old truck died. The Sierra has a 4" Rancho lift kit on it that the previous owner had installed. To keep a long story short, my buddy & I drove to the shop where his old truck was located to pick it up as they were able to make it driveable. He drove his old truck back & I followed him in the Sierra. He lives on a farm with narrow dirt roads & I had to move over to the far left of the road as there was a tractor going in the opposite direction. I hit a roughly 7" deep pothole that I couldn't see as there was grass around it while trying to get around the tractor. After arriving at my buddy's house we both noticed the left front wheel grinding on the well when I turned in, & also that the truck is a little more than 2" lower on the left side than the oppsosite side (Please see pictures, I've uploaded 2 of the side that is lower). My biggest concern is that after spending nearly 2 hours looking over everything, we can't locate the reason for the leaning. Since I was driving it I'm going to have to pay for it, & neither of us are mechanics, so I would greatly appreciate any information as to what the issue could be, if anyone in here has experienced the same thing & what was needed to fix it, etc. Sorry for the long post, I'm new to this.
After very carefully going over the undercarriage pictured below we discovered a crack in the control arm (albeit a small one) & also discovered that the sway bar link on the driver's side is bent fairly badly. Hopefully that's all it is but I'm wondering if those two things alone can account for a 2" drop & the wheel being off center.
