Upgrade to the Heavy-Duty Throwout Bearing Kit


Bert Baker, of Haslett MI. based Baker Drivetrain says: "If you've ever dealt with clutch drag, chatter, or premature throwout bearing failure, you know how frustrating - and expensive - those issues can be. That's exactly why our Heavy-Duty Throwout Bearing Kit is more than just another part - it's an essential upgrade for anyone serious about reliability and performance."

The stock throwout bearing in many Big Twin motorcycles is a known weak point, "especially once you've added performance upgrades or spend time on the road. Our heavy-duty solution drastically improves on the original design with a 97% larger thrust surface and 77% greater static load capacity, which means far less wear and way more durability."

Heavy-Duty Throwout Bearing Kit

Engineered to handle "hard use and aggressive riding", this bearing kit replaces the failure-prone stock parts and is a "simple, affordable insurance policy for the clutch and transmission." Fitment covers a wide range of 1987-up H-D models with cable-actuated clutches.

Also seen here, Baker's new Race Grade Primary Chain Adjuster Shoes "are a smart choice" for most Big Twin builds delivering "reliability where it counts."

Precision-machined from virgin billet Nylon 6-6, "these adjuster shoes have been engineered to deliver greater strength, reduced wear, and a significantly longer service life compared to the original cast components."


Race Grade Primary Chain Adjuster Shoes

Designed as direct replacements for H-D part numbers 39976-65B (1965-2000 Big Twin models) and 39976-01 (2001-2006 Big Twin models, excluding the 2006 Dyna), "these adjuster shoes offer a high-quality solution now that OEM production has ended. Our U.S.-made alternative fills the gap and outperforms both stock cast parts and imported cast copies."

They have been manufactured using modern CNC technology and "proven through real-world use, each adjuster shoe delivers consistent performance you can trust - on the street, at the track, and everywhere in between."

Stronger and more durable than stock components, the reduced rate of wear means increased service life and reduced wear, making them "ideal for demanding performance and high mileage applications."
