Shifter base for NV1500 / NV2550 / NV3500/ NV3550 swap from 2000-2004 Jeep + Dakota

*** For OE replacement see the complete kits instead. ***

Shifter base for custom conversions using NV1500, NV2550, NV3500, & NV3550 transmissions sourced from:

  • 2000-2002 Jeep Wrangler TJ - 4.0L 6 cyl only
  • 2003-2004 Jeep Wrangler TJ - all engines
  • 2000-2001 Jeep Cherokee XJ - 4.0L 6 cyl only
  • 2002-2004 Jeep Liberty KJ - all engines
  • 1999-2000 Dodge Dakota - 2.5L 4 cyl only
  • 2001-2004 Dodge Dakota - all engines
    • (sales codes DDD & DDK)
    • NOT FOR USE IN THESE VEHICLES - see complete kits
  • Does NOT FIT 2000-2002 TJ 4 cyl models (AX5 = sales code DDQ)
  • Does NOT FIT any other models or years - see separate listings
  • Configured for shifter cup receptacle height of 3/4" as original to these models only
  • IF transmission was rebuilt or replaced, it MAY REQUIRE A DIFFERENT BASE. If you install the wrong one it will not work properly and could cause damage. Height can only be confirmed by removing shifter base and measuring transmission as shown in last pic.

A Hurst stick is required (NOT included, sold separately). Other brands and homemade sticks are discouraged. Stick mount has 3/8"-24 threaded holes spaced 7/8" apart on center + mating serrations for a Hurst stick on one face. Due to larger mounting threads (3/8"-24), sticks that use 8mm mounting bolts (most OE, "non-TKO" Lokar, others) will not work. Lokar TKO sticks can be mounted but only to the smooth side of the stub. To select the proper parts:

  • Wait until new transmission is installed to buy shifter parts
    • Remove existing shifter base if present
    • Sit in vehicle, in driving position, with all interior trim (dash, console, etc) in place
  • Define desired knob location in space (neutral position):
    • Measure height from base flange to desired knob location = overall height
    • Measure side & rear offsets from receptacle bore to desired knob location
    • See this diagram for clarification
  • Study the Hurst stick page for shapes that meet your needs
    • Allow 3-6" for stick mount height
    • Choose a stick and see what fulcrum heights are compatible with it (see chart)
    • Check overall height (see chart: stick height + mount height = overall height)
  • Confirm chosen combination achieves desired knob location and that fulcrum height works with stick length selected
    • Consider various stick & stub combinations to optimize
    • Note long sticks on angled mounts will strongly offset knob to left (can be 5-6"+)
    • Note OE dust boot is short and exposes stick mount which helps in tight situations

Stub fulcrum height options (critical to optimizing leverage for short throw):

Option For stick length stick mount height stick mount angle boot type upcharge
A 10" 4.8 vertical Billet Plus default
B 12" 5.3 vertical Billet Plus +$10
C 12"+ 6.3 vertical OE (short) +$20
D 14"+ 7.1 angled 14 deg left OE (short) +$30
G 8" 5.2 angled 11 deg left OE (short) +$10
H 6" 4.7 vertical OE (short) +$10
  • Stick length = point-to-point distance from mount hole to knob thread
  • Stick mount height = distance from base flange to stick bolt hole (affects knob height)
  • Fulcrum height = distance from lower ball to fulcrum pin; varies by option, not published
    • Warning: Follow stick length guide to avoid excess effort & component failure
  • Core / Hurst kit for Wrangler uses Option C
  • Core / Hurst kit for Cherokee uses Option B
  • Core / Hurst kit for late Dakota is specialized (not offered separate from kit)
