Question on changing legal GCWR
While looking for an 8.1 Burb, I come across some 3:73 models which have a factory GCWR of 16K. Since the only change to the GCWR of 19K with the 4:10 models was the gears, has anyone changed the gear...

Another to look and think about. Is actual gradability of your truck. A rig with 400 lb ft of torque, a 16-1 over all low ratio with stock 30.5" tires has a max starting ability of 15-17% at 20k lbs. Make the overall low 24-1, you can now pull a 30% grade. That's the difference in one of my trucks with the 14500 gcwr auto, lower ability. Vs the 12500 gcwr with a 5 sp manual, believe it or not, better performer. Back in 90s, GM lowered the gcwr by 2000 lbs with the nv4500, Dodge on the other hand, increased gcwr with the nv4500. Reality from a performance standpoint, the NV4500, kicked both auto transmissions ability's.
If you boat ramp is in the 15-20% tell like a few I know of here in puget sound region, having lower gears all around for slow speed stuffed good. With 4wd, you do have 4lo which can save you bacon, vs numbers I quoted in rwd/4hi. For youruseage, I can see how a 3.73 change out to 4.33/4.56 would be better than a 4.10. as you appear to be doing local stuff, vs over the road stuff like Don did, others on here.
