Unlike the high-output 6.2L transmissions, the 8HP70 behind a 5.7L uses a 23-spline output shaft, so this kit is a straight female-to-male spline match rather than a step-down conversion.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe kit centers on the same 5.7\/6.2 8HP70\/8HP95 adapter housing (51-9905) used across the Advance Adapters transmission adapter line, paired here with a shaft specced Jeep 23 female x Jeep 23 male (52-9901). That shaft carries the transmission's output straight through to a 23-spline male end, ready to mate with a compatible transfer case input.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eOne important fitment note straight from the listing: some applications may require the spud shaft to be shortened. That's worth confirming against your specific transfer case and driveline setup before final assembly — it's a heads-up worth passing along rather than assuming a drop-in fit every time.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWhat's included:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e5.7 and 6.2 8HP70\/8HP95 Adapter Housing (51-9905)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eShaft, Jeep 23 Female x Jeep 23 Male (52-9901)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSealed Bearing 209RS (716308)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSnap Ring, T350\/T400 (716450)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eTrue Arc Snap Ring (716456)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eAs with the 43-spline version, the sealed bearing and snap rings come included so the shaft is fully supported and retained in the housing without sourcing those separately.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis is the right pick if you're mating a 5.7L HEMI-based 8HP70 (not the high-output 8HP95) to a transfer case that needs a 23-spline input — a common combination for Ram 1500 and Grand Cherokee-based swaps.\u003c\/p\u003e","brand":"Advance Adapters","offers":[{"title":"Default Title","offer_id":44666287947842,"sku":"50-9905","price":600.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1476\/5984\/files\/0004925_ram-57-grand-cherokee-57-8hp70-23-spline-output_625.jpg?v=1785623288","url":"https:\/\/www.skinnypedalracing.com\/products\/ram-5-7-and-trail-hawk-5-7-8hp70-23-spline-output-50-9905","provider":"Skinny Pedal Racing","version":"1.0","type":"link"}
