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.
All shifter packages are made to order, so lead time (the time between placement of order and shipment) can be anywhere from 3-7 days. It's nearly impossible to get previous customers to return their stock shifters-- my return rate is less than 10%. I don't print the shipping label until the package is complete, so as soon as you receive a notification from the USPS, you will receive your shifter package 2-3 days after that.
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 $25 for shafts.
