Please also check out the statistics and reliability analysis of the 2011 Chevrolet Silverado 1500 based on all problems reported for the 2011 Silverado 1500.
Rear axle has a gvwr of 3950 lbs the vehicle a 2plus 1 rear spring pack, 3 diferent 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 componet controls the gvwr is being violated by Chevrolet I have a truck marketing institute certificate in this area and a cd from michelin verifing the weakest componet controls gvwr. I asked Chevrolet for replacement springs from another model that has a combined rating of 4050lbs 100 lbs above ther 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.
