Pros:1. Improved durability: A starter drive extension shaft can help increase the lifespan of your Harley-Davidson's starter drive. By absorbing the torque and stress produced during starting, it can help prevent damage to the original starter drive, ultimately reducing the need for frequent repairs or replacements.
2. Convenient installation: Installing a starter drive extension shaft is typically a straightforward process that can be done by an experienced Harley-Davidson mechanic or an enthusiastic home mechanic with the proper tools and knowledge.
