Rear axle has a gvwr of 3950 lbs the vehicle a 2plus 1 rear spring pack, 3 different spring suppliers rate this spring pack at 1425L or 1500 lbs each for a combined rate of either 2850 or 3000 lbs per pair. Which makes the factory rating of 3950lbs either 1100 or 950 lbs higher depending on the spring supplier. Using the industry guideline the weakest component controls the gvwr is being violated by Chevrolet I have a truck marketing institute certificate in this area and a cd from Michelin verifying the weakest component controls gvwr.I asked Chevrolet for replacement springs from another model that has a combined rating of 4050lbs 100 lbs above there 3950 lb axle rating. This issue has caused trailering problems but Chevrolet refused this is a safety issue the springs I requested would correct the problem can you help? I can supply further information if needed thank you
