[lxhatch91]

hi guy i want to change my gear ratio from stock 8.8. 2.73. to 3.73 . I need some help about the shim for pignon . What is the difference about the stock shim thickness and the one i have to put for 3.73 because i dont want to remove and repress the bearing on pinion hundred time to get the right depht

Only way to tell is by using a pinion depth gauge or by "removing and repressing a hundred times". 8.8" rear ends and the ring and pinion gears that go in them are not precision machined components. Ergo, there is no "standard" shim that you use for a given gear ratio.

EricTheCarGuy actually did a pretty well documented how-to on setting up an 8.8" rear end that shows some tricks to get around having to remove and press the bearing every time if you don't have a depth gauge.
