My current setup needs new gears front and back aswell as new driveshafts. I installed a 14bolt FF with 3.73 gears and converted my 10 bolt to 8 lug. It has 2.73 gears. I also have a 454/TH350 and 208 setup. With the 38" TSL's is just installed I dont think I should get the shafts made up until I upgrade my transfer case because Im afraid it won't survive. I need to regear the front no matter what because of the miss match. I can get the set of 3.73's from the 10bolt 3/4 ton I got the 14bolt from and switch them to make them the same. I was thinking what If instead of getting new gears like 4.56 or 4.88's I keep the 3.73's and upgrade the 208 to a 203/205 doubler setup then buy shafts instead of geeting a 205, lower gears and new shafts. This way I will get better gas millage on the highway with the TH350(No overdrive) and with the 4.1 ratio I will get a better crawl ratio then 4.88's and a 205. 2.52X2X4.88 = 24.6, 2.52x4x3.73 = 37.6. Seems like a much better setup and advantage to me. I also want to upgrade to a D60 when I find one, so I dont feeling like wasting money on new gears and the install costs on the 10 bolt. Also this would be the last pair of shafts I ever buy unless I brake one of course. I priced out a doubler at northwest fabs and it was $1700 canadian. This would be around the same price to get new gears installed. When I get a D60 I will go to lower gears but for now I think this will work out good. Do you guys think this would be a good idea, and if not why? Has anyone else thought about this setup aswell or something similiar?
