T56 GM Input Shaft 29 Tooth 1386-585-007

T56 GM Input Shaft 29 Tooth 1386-585-007 If you’re rebuilding a Tremec T56 “011” unit (1386-000-011) and need to replace the input shaft, you’ve come to the right place — and you already know how rare this part is. The 011 was a short-production T56 variant produced from the late 1990s to early 2000s, originally designed for swap and conversion applications to replace the T5 in GM vehicles. This is a genuine original Tremec input shaft — new old stock — and one of the last remaining examples of a part that has been discontinued for years and is nearly impossible to find anywhere else. Specifications 29-tooth / 26-spline 11 1/8″ length Fitment GM “011” unit 1386-000-011
