Cable Exit?
Most Kwik-Shift Shifters can be ordered with either a FRONT or REAR cable exit. However, it is important to understand how this affects other aspects of the shifter design.
Cable exit determines:
- The up-shift pattern of the shifter, whether it is a PUSH to up-shift or a PULL to up-shift
- Whether the PARK location sits toward the front of the vehicle or toward the rear.
- (On Air Shift applications) Where the air solenoid will mount (Kwik-Shift II), or where the CO2 lines will connect (Kwik-Shift I).
- On Electric Shift applications (GM Powerglide), “if” or where the solenoid will mount.
Kwik Shift I Air Shifter part #485B (Chrysler 904 and 727, ProFlite, Reverse Pattern Valve Body with Clean Neutral)
#485B-FT – Front Cable Exit = PULL → up-shift pattern :::: FRONT of Vehicle (P-R/N-1-2-3-N)
#485B-RE – Rear Cable Exit = PUSH ← up-shift pattern :::: FRONT of Vehicle (N-3-2-1-N/R-P)
Please note from the above examples:
- Cable Exit
- Front of vehicle
- Up-shift pattern (push vs pull)
- Location of PARK
Cable Length
For FRONT exit shifter applications, a 7.0′ (2.13m) or 6.0′ (1.83m) length cable is common.
For REAR exit applications, a 5.0′ (1.52m) or 4.0′ (1.22m) cable length is common.
Front exit applications must make two u-turns between the shifter and transmission (see image below), and rear exit applications make a single u-turn. Making these bends too tight may cause premature failure of the cable lining. Keep the bend radius greater than 10″. Choose the cable length carefully.
The images below provide an overly simplified example of shifter cable routing for both front-exit and rear-exit shifter applications.
What Else?
The modular design of the Kwik-Shift shifter allows the builder/vehicle owner to only purchase those items necessary to complete the installation. Precision Performance does not believe in selling the customer a box of parts (a kit) that either includes items that will never be used or includes the wrong parts for the specific application—forcing the customer to spend additional funds to complete the installation.
Here are common items needed to complete shifter installation:
Floor Mount Brackets – Door cars may need floor mount brackets, whereas a dragster will not. Some builders may decide to fabricate their own brackets. This often occurs on those applications with either a tall transmission tunnel or not using an air shifter. Another concern is height. The highest point from the base of the floor mount brackets to the tip of the handle button is 12.5″ (31.75 cm).
Shifter Cable – A person may already have a shifter cable that is the proper length and design. For FRONT exit shifter applications, a 7.0′ (2.13m) or 6.0′ (1.83m) length cable is common. For REAR cable exit applications, a 5.0′ (1.52m) or 4.0′ (1.22m) cable length is common. Front exit applications must make an “S” turn between the shifter and transmission, and rear exit applications simply make a “U” turn. Making these bends too tight may cause premature failure of the cable lining—choose the cable length carefully.
Cable Bracket and Lever – Offered individually or as a kit, these items provide a secure connection point between the cable and the transmission. If the transmission already has a lever attached to the shaft (for the end of the cable to attach), a new lever may not be necessary. Proper geometry is key.
Air Cylinder – For Kwik-Shift II applications. Note: We recommend the Kwik-Shift I Power Shift shifter for air operation. Air cylinders for the Kwik-Shift II shifter are often purchased after the fact when the user decides to add air shifting to what was once a manually-shifted KS-2.
CO2 Kit – For air shifter applications, this kit includes the remaining items (less controller) to complete an air shifter installation. (CO2 bottle, line & fittings, valve, solenoid).
Thumb Button & Bracket – Many racers still prefer a thumb button on their shifter to control a staging lock, trans brake, backup lights, etc. Note: On Kwik-Shift I applications, the top button in the handle is wired to a micro switch in the shifter case for trans brake activation.
Other Items: Electric Shift Solenoid (Only available for specific 2-speed GM Powerglide shifter part numbers); Quick disconnect, trunnion, or ball & stud, for shifter cable (at transmission); Starter Switch Relay
