Shifter base for NV4500 swap from 1998-2005 Dodge Ram HD
*** For OE replacement see the complete kits instead. ***
*** Pics are of the similar NV5600 shifter I also sell. NV4500 shifter is the same except there is no lower pivot bushing and the lower ball has flats on each side. ***
Shifter base for custom conversions using NV4500 5-speed transmissions sourced from:
- 1998-2005 Dodge Ram 2500 & 3500 HD trucks
- NOT FOR USE IN THESE VEHICLES - see separate listings for complete kits
- Does NOT FIT NV3500 or any 6 speed
- For GM models, see separate listings; NV4500 is NOT universal!
Configured for square top short lid w/ casting # 25137 (1.75" stub depth w/o gasket)
- Does NOT FIT 2001+ GM NV4500 (lid casting # 33893, 1/4" taller mount)
- Does NOT FIT earlier years w/ "round top" lid (see last pic)
- For more info see the NV4500 lid page
A Hurst stick is required (NOT included, sold separately) - NOT negotiable. Other brands and homemade sticks are will NOT fit! 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 4" 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"+)
- Requires a Hurst stick directly mounted on side w/ serrations
Stub fulcrum height options (critical to optimizing leverage for short throw):
| Option | For stick length | stick mount height | stick mount angle | boot type | upcharge |
|---|---|---|---|---|---|
| F | 18"+ | 4.15 | angled 14 deg left | Billet Plus | default |
- Stick length = point-to-point distance from mount hole to knob thread
- Stick mount height = height from base flange to stick bolt hole
Kit includes mounting hardware, dust cover boot, and instructions. The base is built by Core Shifters using proven Hurst Billet Plus components inside a custom housing:
