Upgrade your original Billet RSX Shifter (KTD-RSX-SFT) to the stronger Race-Spec Billet RSX Shifter (KTD-RSX-PRO). Taking apart your shifter can be difficult. We offer the upgrade service at no cost to you. You must cover shipping both ways and pay for the product. This is a good option for people wanting to make sure that everything is put back together perfectly and inspected. If you are up to the task you can purchase the upgraded arm and take your shifter apart. Make sure to take notes of disassembly as there are not instructions for assembly.
