Description
AS-8603, 3/4″ Spacer Rotation Ring Transfer Case Spacer.
This is a 3/4 inch spacer needed on some late model transfer cases to make the #10A adapter fit.
(Will require some slight fitting on 2007 6L Hummer H2)
Needed on Borg Warner transfer cases used on Hummer 2 and Cadillac Escalade.
Can also be used as a clocking ring to turn the transfer case.
The spacer adapter #AS-8603 is commonly used on transfer case conversions to alleviate fitment issues caused by variations in transmission output shaft lengths.
Many transmissions have positive “stick outs” on their output shafts in relation to the edge of the rear tail housing or adapter.
This causes the output shaft to be too long; therefore, causing a bottoming out effect when installing your transfer case.
For some applications, the output shaft can be trimmed back.
There are however several applications where there are simply not enough splines on the main shaft.
The #AS-8603 is a 3/4” spacer to be used where trimming is not desired or an option.
