BAKER DRIVETRAIN Shift Kit (manufacturer part number: CD6N1-602-M8) — a drum/support kit designed to achieve sharper and smoother gear shifts on 6-speed Cruise Drive gearboxes. Made from machined 6061‑T6 aluminium, it directly replaces the original assembly for easy installation from the bearing door, without disassembling the gear train.
- Gear Shift: fixed-axis drum and advanced groove geometry to reduce friction and decrease the effort required for each shift.
- Mechanical Reliability: machined pillow block in 6061‑T6 and precision-machined shaft/drum for high durability of the selection drum.
- Neutral Selection: redundant neutral function and improved geometry ratchet for safer and more repeatable neutral detection.
- Integrated Components: linear ratchet bearing on the right mounting plate, seals and fasteners included — reuses the original fork, centering pin, and shafts.
- N1 Pattern: 0-down pattern, all the way up — neutral under 1st to limit neutral grabs during aggressive 1→2 shifts.
- Origin: made in the United States.
