GearSwitchers

 Three Gearswitchers.  From left to right:  2.0", 1.0", and 1.5" reductions.


This is the product page for Doctor Isotope's GearSwitchers.  The Default GearSwitcher has a 50% throw reduction and a 1.5" height reduction compared to stock.  It's also 15% shorter than a TWM Stage 2.  Packages range from just a shifter with cage bushings, all the way to a shifter mounted in the cage with full solid bushings and a shift knob.  You can read more about them in the product descriptions below.

After ordering, please contact me via e-mail to let me know your desired height reduction (all packages) and your shift knob choice (Ultimate and Extreme only).

 

Please Note:

Buyers have 30 days from receipt of shifter to return the core for full core value fee refund;  cores received after 30 days are eligible for half of the core value fee, that is, $40 for assemblies and $20 for shafts.
