At 1.25\" in length, it's noticeably shorter than the AS-6455 kit, and it's machined from 356-T6 heat-treated aluminum alloy for strength.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eImportant compatibility note straight from the listing: this adapter is used exclusively with 4L80E 4WD models, and it must be paired with Advance Adapters' 4L80E VSS kit (50-6409), which is sold separately. Without that VSS kit, this adapter alone won't complete the transmission-to-transfer-case signal path — so if you're speccing this swap, budget for both parts together rather than assuming this one adapter covers everything.\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\"\u003eAdapter, 4L80 to Atlas, Short (51-6408)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBolt, 10mm 1.5 x 35mm SHCS 12.9 Zinc (720028)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis is a lean, purpose-built kit — just the short adapter housing and its mounting bolt.
