Shifter base for TR6060 swap from 2008-2017 Viper or Falcon FG
Shifter base for custom conversions using TR6060 transmissions sourced from:
- 2008-2017 Dodge Viper
- 2008-2016 Ford Falcon FG / X (Australian)
- NO other TR6060 models - see separate listings
- Tail location only (see pic) - does NOT FIT forward location aka "inspection port"
- NOT FOR USE IN THESE VEHICLES - see complete kits
Mounts at tail location on a rectangular 4-bolt pattern that is ~ 2.88" wide x 3.44" long; stub pivot ball center is ~1.2" below the flange
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"+)
- 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 | upcharge |
|---|---|---|---|---|
| A | 8" | 3.1 | vertical | default |
| B | 10" | 3.6 | vertical | +$10 |
| C | 10"+ | 4.6 | vertical | +$20 |
| D | 12"+ | 5.4 | angled 14 deg left | +$30 |
| E | 13"+ | 4.3 | angled 14 deg left | +$40 |
| F | 14"+ | 4.5 | angled 14 deg left | +$40 |
| G | 6" | 3.5 | angled 11 deg left | +$10 |
| H | 5" | 3.0 | vertical | +$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
Kit includes mounting hardware and instructions. The base is built by Core Shifters using proven components inside a custom housing:
- Billet steel gear selector stub
- Hardened steel cross-pin & stainless steel fulcrum pivot ring
- Self-centering cross-gate bias springs with heat treated spring seats
- Glass-reinforced polyamide fulcrum socket with steel wear clips
- Extruded aluminum housing with Spirolox steel support ring
- Zinc-plated laser-cut steel base-plate & cover
- Rubber oil control seal with steel retaining ring
- Vibration-resistant serrated flange head steel retaining bolts
