I answered this call today. At first I didn't but they called back so I answered it the second time. They asked my name I said yes and he said they wanted to extend my chevy silverado Warranty. I told him I've had a previous call about this and I declined also a letter. He then asked if I had any modifications to my silverado and I said yes it's a rocky ridge package from the dealer. He asked if it was lifted I said yes from rocky ridge conversions. He then asked how Man many inches I said 6 inches he replied with sorry to bother you we can't extend a warranty if your vehicle had been lifted over 2 inches.
