Shifter base for conversion using C5 / C6 / C7 Corvette driveline

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

*** Not quite as pictured but very similar. Same concept but baseplate is smaller to fit application. ***

Shifter base for custom conversions using a 1997-2019 Corvette driveline:

  • Fits onto OE shifter box that mounts onto OE torque tube found in:
    • 1997-2004 Corvette C5
    • 2005-2013 Corvette C6
    • 2014-2019 Corvette C7
  • Allows use of a Hurst bolt-on stick (see below)
  • NOT FOR USE IN THESE VEHICLES - see separate listings for complete kits

Mounts on the OE specialized remote linkage framework for rear-mounted transaxle configuration with shift rail entering through front of case (see pic). For swaps using complete Corvette chassis only. Rectangular 4-bolt pattern that is ~ 1.6" wide x 3.1" long; stub pivot ball center is ~1.4" 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"+)
    • Note OE dust boot is short and exposes stick mount which helps in tight situations
    • 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
A 8" 2.9 vertical Billet Plus default
B 10" 3.4 vertical Billet Plus +$10
C 10"+ 4.4 vertical OE (short) +$20
D 12"+ 5.0 angled 14 deg left OE (short) +$30
G 6" 3.4 angled 11 deg left OE (short) +$10
H 5" 2.9 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

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. This kit has many superior features & components, integrated into a unique, exclusive assembly:
