Many from this forum have ordered custom made grade 8 u-bolts from Boise Spring Works out of Boise Idaho. I believe they said they cost them around $45 shipped and they arrived pretty quickly. They have torqued them to 120 ft/lb with no issues.

 

Give them a call, (208) 377-1157.

These are the torque specs I used on my 2014

1500 when I installed my 2.5” kit. Worked great for me and have had no issues, just be sure to recheck and re-torque after you drive some and everything settles.

So... if I used the supplied MotoFab u bolts and torqued them to 120... even though spec is to 55 and then 130 degrees..... is that bad? is something horrible going to happen over time? 

 

I have a nearly perfect memory, and I know that when we did my buddy's truck in 2014 that the instructions to his kit said to torque to 120, so that is what I did on mine in 2020.

Torqued my motofab 2” rear lift block with new ubolts to 100 ft lb. Have driven 1500miles and recheck torque. Were still at 100ft lb.

      My house is set at 75. My car at 70. When I have guests the house is at 70.

      OK you say you could hang meat but what was the actual temp? One of the AC systems job is to remove humidity that we feel on our body your new system removed alot of humidity as that is were the water comes from on the ac coils and that made it feel colder. 80 degrees with high humidity will feel hot vs 80 degrees with low humidity will feel alot cooler.

      I was using recirc/max air. Especially if it really hot i start out by lowering the front windows a little with regular ac the go to recirculation after a few and rolling windows up. And it does not have the newest refrigerant. It has per the info under the hood r134. Not the new r1234yf.

      AC diagnostic on a neo-classic Camaro

      By Atlas · Posted

      tldr; Shade tree mechanic stumped by variable displacement AC compressor.   Not Silverado related, but for my 2000 Camaro SS. I've never really used the AC since acquiring the car a good handful of years ago. I plan to take it on a trip this summer so I wanted to make sure the AC was in good shape. On an 73 degree day in the shop with the car idling I set the AC on "Max", temp set to cold, and fan on hi. The compressor turned on and air turned nice and cold.   I let it run for several minutes but noticed the compressor never cycled off. The engine was up to temperature enough that it began cycling the cooling fans on high. I had a set of manifold gauges hooked up and it was consistently at about 25 psi on the low side and between 200 and 225 psi (warm engine) on the high side. Per temperature charts, the low side is low (should be 30-35) and the high side is a little high (up to 170 per chart). I read the low pressure as potentially being under-charged underscored by a continually running compressor This was also underscored by temp readings of mid-20 degrees at the vents. Not just cold, freezing cold. Switching off the AC but leaving the HVAC fan on high produced a deluge of condensation underneath the vehicle. I was getting ice buildup on the evap core most likely.   The low reading (25psi) concerned me that the compressor wasn't switching off so I swapped out the pressure switch. No change in behavior, still ran constantly.   The AC clutch works fine as it engages/disengages with the HVAC switch on command. The compressor relay is good as I swapped it with two different known good relays just to be sure. Having eliminated that, and the pressure switch, I added refrigerant, thinking the constant run and low "low" pressure were signs of a slight undercharge. Makes sense, the car is 26 years old and it doesn't appear the AC system has ever been touched.   Adding some R134a didn't meaningfully change the low side pressure. And that's when a lightbulb flashed upstairs. While I consider the car "old", it's possibly "new" enough to have a variable displacement compressor. Did some reading and sure enough. Dangit. I don't work on these for this reason.   Adding refrigerant means the compressor will just compensate and won't really change pressures until it's severely overcharged or undercharged. But at least I wasn't getting ice/frost anymore, but instead high 30 degree temps out of the vents. That's more normal, but with variable displacement now I have no idea where my charge level is at. It's probably overcharged now. The high side even with the engine radiating serious heat was never really over about 225.   The static pressure at room temperature is dead on, before and after the charge. Both high/low equalize after some rest.   I'm thinking I'll need to take it to a shop. I want the proper charge level so I'm not working the compressor too hard. The only way to get an accurate charge is to evacuate and then re-charge with the exact amount specified for the system -- at least that's what I'm reading.   Anyone here with modern automotive AC knowledge?

      Mine is in the shop for the AC now. While it did get cold after a bit, it would take a while to even start to cool the air at all. Turns out the compressor was bad and cycling.
