The ComeUp Seal Slim 9.5rs is the official GM/AEV part for my truck. It was modified to include a longer wiring kit for controller relocation, modified fairlead & longer free spool handle. Around $1,850 to $2,150 depending where you source.
I just don’t believe it was properly sized for a 7,300# GVWR. It should have been the Seal Slim 12rsi you noted. Ironically that is the winch they use on the heavy duty 2500 version of my truck — with similar modifications to qualify as the official GM/AEV part number.
ComeUp has a pretty good rep & quality from what I can tell — haven’t personally ran one yet. As you probably know, the parent company (ComeUp) is located in Taiwan which is where all the winches are also made. Their US presence (aka ComeUp USA) is located in the same town as Warn which is Clackamas, OR. I spoke with Rob, their general manager, when I was considering them and he was a wealth of information. He had been with ComeUp for about 30 years and helped start the US operations. A genuinely great guy all around. No idea about the rest of their operations but he impressed.
I just had a hard time justifying spending more dollars on the ComeUp winches than the Xeon XC I got. And had I went with the smaller XC-12s it would have been another $120 cheaper.
Admittedly I could have been okay with a 12k. My only thoughts with the larger 14k was layer count. Depending which layer I’m on I get about 1,100 - 1,700# extra pull strength. This just gives me more flexibility to not have to spool all the way out to hit 12k. For instance the winch is rated for 11,544 on layer 2 as opposed to 9,895 on the 12k version.
I use the Safe Xtract app to enter grade angle, soil type, number of wheels buried, GVWR, etc to determine total pounds of resistance. While I am sure it’s not perfect it gives me a really good idea how much resistance I am tackling and gives me a shot of setting up my rigging appropriately. I won’t be just blindly trying to do 14k pulls for reasons you already noted.
Below is an example of rigging needed for a 9,500 winch under select conditions. With mechanical advantage it’s possible but even puts you in the caution zone on a double line pull. A Spanish Burton gives you some overhead but is more complex.
The 12k or 14k winch simplifies rigging.
