I just had to give a shout out to Timbren!! Earlier this year I paid to have a set of Timbren's on my 2011 Ram 3500....as it turned out it when the truck accessory store installed them they left to large of a gap (which I wondered about) and they used the normal Timbren. I finally had some free time to talk to Timbren and found Murray to be a huge help. He informed me that I had the wrong Timbren's (that I should I. Fact have the heavy duty version) and that the gap was in fact to big. That said he sent a brand new set of Timbren's with more spacers then necessary for free!! And didn't even charge me shipping. I was very impressed and actually quiet amazed! I installed them today and can already tell a substaintial positive difference!!

X-2. I had something close to your situation, and they took care of it with no questions asked. They are an excellent company, and I am very pleased with their product.
