George will certainly go though your drives and let you know what is needed to get them back to stock if that is what you are asking. He may suggest some things that will make them stronger/better depending on your usage, but I guarantee he will not force you to buy any upgrades that you don't want or absolutely need. AADS is very honest and transparent, no scams, you absolutely get exactly what you agree upon and more. The employees are very skilled and friendly. Customer service is outstanding. Just my observations!

+3 for AADS. Had them do my drive, one year later hit a log and made a mess of the drive. He worked with the insurance company to get it covered 100%. Where else do you get a 24 month warranty on a drive with more than stock horsepower? He does have some really good ideas on basic drive improvements. He has thousands of broken parts and has really made some significant improvements.
