The spacer adapter #AS-8610 is commonly used on Atlas 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 tailhousing or adapter. This causes the output shaft to be too long; therefore, causing a bottoming out effect when installing an Atlas. 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-8610 is a 1/2” spacer to be used where trimming is not desired or an option.
Note: This spacer will not work on a New Process transfer case as it interferes with the retainer bolts of the NP transfer case. If a spacer is needed for a stock Jeep New Process, please use the 3/4" one we offer P/N AS-8603.
