Check this out... 1) Weigh your truck at all 4 wheels. We're looking for the weight at each wheel. 2) Throw some metal rods in place of the front shocks 3) Jack up the rear 10-20" or so 4) Weigh the front wheels Now: CGH = Center of Gravity Height CGwb = Center of Gravity in wheelbase (from behind the front wheel centerline) CGtrw = Center of Gravite in track width (from left side of track width) WB = Wheel Base TrW = Track Width HT = Height Raised FW1 = Front Weight before jacking FW2 = Front Weight after jacking RW = Rear Weight RtW = Right Side Weight TW = Total Weight Having said that: tan x = HT / squareroot( HT^2 + WB^2 ) FWc = FW2 - FW1 CGH = ( HT * FWc ) / ( TW * tan x ) CGwb = ( RW / TW ) * WB CGtrw = (RtW / TW ) * TrW Keep in mind CGH in from the centerline of you axles. Now you can go paint CG spots on you truck. You will roll over when your CG spot passes your wheel.
