{"product_id":"atlas-transfer-case-3-4-spacer-rotation-ring","title":"Atlas Transfer Case 3\/4\" Spacer\/Rotation Ring","description":"The Advance Adapters AS-8603 is a 3\/4-inch spacer and rotation ring engineered for Atlas transfer case installations. Many transmissions feature a 'stick out' on their output shafts, which can cause a bottoming-out issue when an Atlas transfer case is installed. In situations where trimming the output shaft is not practical or possible due to a lack of sufficient splines, this spacer provides a solution.\n\nConstructed from aluminum, this spacer measures 3\/4\" in thickness. It functions by creating additional clearance, ensuring proper installation and alignment between the transmission and the Atlas transfer case. The AS-8603 is a key component for custom drivetrain builds and swaps where precise fitment is critical.\n\nIncluded with the spacer are necessary mounting bolts (3\/8\" -16 X 1.00\" SHCS ZINC). Test fitting the ring to both the transmission and the Atlas transfer case is recommended to ensure proper alignment with all mounting holes.","brand":"Advance","offers":[{"title":"Default Title","offer_id":52686806647096,"sku":"AS-8603","price":99.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687885055.jpg?v=1784876950","url":"https:\/\/store.motormia.co\/products\/atlas-transfer-case-3-4-spacer-rotation-ring","provider":"MOTORMIA","version":"1.0","type":"link"}
