These are CNCed from 7075-T6 aluminum and anodized, which is much stronger then the stock cast aluminum fork. They have been analyzed and the typical failure points were targeted on the stock fork, so a better one was made! 100% made in the USA! The stock 3-4 fork isn't very durable for racing applications. They can wear out or break from hard shifts. This is a nice upgrade for anyone already rebuilding/upgrading their R154 transmissions, and is now included as an option in our ultimate rebuild kit!

Please note that we typically try to send a Marlin Crawler version, but we might also use a different supplier of the same quality if there is an extended wait time.
