If you're looking to upgrade your clutch setup, the Advanced Clutch Monoloc Collar 884006P is a solid choice. This isn't just some run-of-the-mill part; it's a one-piece wonder that replaces the standard two-piece wedge collar and wire ring found in pull-type clutches. You know how frustrating it can be when things aren't aligned just right, especially when you're pushing your car to the limits. Well, this collar is designed with a spring tension that’s been meticulously calculated and tested to ensure everything stays in line, no matter how you drive or what mods you’ve made to your ride.
Built from hardened chrome-moly steel, this collar is tough as nails and ready to take on years of abuse. I’ve seen firsthand how it dramatically improves the life of your release mechanism, so you can shift with confidence, whether you're on the track or just cruising around town. And let’s be honest, who doesn’t want that extra peace of mind when slamming through gears?
