So, I've got a 2015 GMC Sierra that I use to pull a trailer, with the NHT setup.
Very low mileage. Have not hit 45,000 KMS yet. But it broke on me last year and dropped an AFM lifter. Under warranty, but still cost me ~$1,500 as I was on holidays at the time and had to have it towed home, plus renting a 1 ton to get my trailer (underwhelmed by the GM 6.6L gas BTW). So I'm thinking I either sell it and buy a Ford with the Godzilla (don't want the headaches of diesel) or keep it and make it more bulletproof. Given the state of getting a new vehicle right now, and how unlikely it is I upgrade my trailer any time soon (RV market is similar to truck market, except the QA has gone to ******), I'm thinking it's time to dump the AFM properly.
So, what do I need to dump the AFM and build a reliable trailer rig? Options all the way up to a Procharger if it is useful. Bigger issue is finding a shop capable of doing it. I'm in Central BC, Canada.
I get that I'm talking cam and lifters, but what cam? And does the stock tranny (6spd) need anything? Truck has the bigger 3.73 gears, so I doubt I would upgrade those.
Any advice? Anyone done something similar?
Thanks for any input.
