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"+)
- Options E & F require 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 |
|---|---|---|---|---|---|
| E | 15"+ | 3.9 | angled 14 deg left | Billet Plus | default |
| F | 18"+ | 4.15 | angled 14 deg left | Billet Plus | +$10 |
- Stick length = point-to-point distance from mount hole to knob thread
- Stick mount height = height from base flange to stick bolt hole
- Core Shifters kits for Ram use Option F
