Using this K - Tuned Gear Lockout is straightforward. First, make sure you have the K - Tuned V3 Billet RSX Shifter because this lockout only works with it. The unit comes with all the required hardware for installation, so just follow the included instructions to attach it to your shifter. When you're driving, the spring - loaded pin will keep the shifter out of the 5 - 6 - R section, letting you focus on shifting to the 4 corners. Since it's manually operated, you'll have to control the shifting yourself. As for maintenance, periodically check the solid steel components for any signs of wear or damage. Keep the parts clean and lubricated to ensure smooth operation. And always remember, this lockout doesn't come with the shifter, so you need to have the K - Tuned V3 Billet RSX Shifter already.
