No I was running factory 17's with tires that were around 31" tall, the stock 20's with the factory tires are 33" tall so that brings my final drive down. On the other hand I still used second prime with the stock 20's my trap with 17's was 98 and best trap with the 20's was 96 and my truck goes into second prime somewhere around 85mph and I do have the stock 3.55 gears still
