Description: *** This listing is only for the default fulcrum height indicated below (for 8" stick length); FOR ANY STICK LENGTH GREATER THAN 8" - DO NOT BUY THIS LISTING! - YOU NEED ONE OF THE OPTIONAL FULCRUM HEIGHTS not sold on eBay - go to our website.*** *** File photo of similar model *** Shifter base for custom conversions: Fits Tremec TKX 5 speed aftermarket transmissions Does NOT FIT any other model - see separate listings Replace the Tremec-supplied base with a higher fulcrum to reduce throw Tremec's fulcrum height is only 1.9"; follow the chart below for substantial improvement! Mounts at tail location on a rectangular 6-bolt pattern that is ~ 2.2" wide x 5.5" 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" 3.7 vertical Billet Plus default B 10" 4.2 vertical Billet Plus +$10 C 10"+ 5.2 vertical OE (short) +$20 D 12"+ 6.0 angled 14 deg left OE (short) +$30 E 13"+ 4.9 angled 14 deg left Billet Plus +$40 F 14"+ 5.1 angled 14 deg left Billet Plus +$40 G 6" 4.2 angled 11 deg left 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.
