    I was putting my plow on tonight, possible snow showers the next few days, and I decided to measure how much the front end of my truck sags with the plow up. 3/4-of an inch!!! I was surprised. I thought it would drop a lot more than that, being a 1/2-ton and all. No load boosters by the way...

    Be glad you have the Z71 springs. The regular 1500's sag a lot more. If I remember right the FAWR with the Z71 pkg was ~3800lbs, plenty for a plow.

    3925 Front, 3750 Rear. Wait a minute, wouldn't this make my GVWR around 7675-lbs.???? Let's say my plow weighs 550-lbs., my spreader weighs about 350-lbs., I weigh about 145-lbs. soaking wet... which leaves 6630-lbs available. How much do you think a 1/2-ton ext.cab short bed weighs???

    Your FAWR and RAWR add up to more than your GVWR.

    Plow weighs 7-800lb. or so, depending on make/model.

    Truck empty is around 4800-5000?

    My 94 excab swb Z71 stepside weighed 5022 at the race tracks scales.It was a HD 1500 with the 4800 lb rear end.Its GVWR was 6600.If you have the 10 bolt rear your GVWR is 6200,if you have 14 bolt rear,you are at 6600 to.My Z71 excab held my 715 lb Fisher Minute mount very good.My cousin has a 96 Z71,excab and he has a Boss V 7'6" on it,it sags a lot more than mine did with the Fisher.When you measure sag with an IFS truck,you need to lower the plow,drive forward at least 10 ft,get out measure,raise plow,then drive forward again to let the suspension ,and tires squirm out,then remeasure.I bet your sag is more like 2-3" when you do it that way.If you have a solid axle truck,just raise,measure,lower,measure.
