If you are a Harley rider, you’re likely looking for a primary chain tensioner that will work as well as possible. You can choose between a Manual or an automatic one. We’ll go over the benefits and drawbacks of each type and recommend the best one for your needs. You can also read our review of the Tension Reliever from Twin Power. Listed below are some of the best choices for the primary chain tensioner on Harleys.
Manual harley primary chain tensioner
If your bike’s chain is too tight, it can cause premature failure of the engine, transmission, and primary bearings. A factory automatic primary chain tensioner is usually the culprit. To prevent premature engine and transmission failure, purchase a Twin Power Tension Reliever. It will allow the chain to be properly adjusted for safety and performance. The Twin Power Tension Reliever fits most Harley models, including the Dyna, FLT, and Softail.
This kit replaces the original factory automatic tensioner, making it an ideal upgrade for big displacement, high performance engines. It locks the chain tension in place during shifts, so there is no need to change the tension during severe shifting. The kit includes mounting hardware, but does not include a primary chain gasket. The adjuster does not include a primary chain gasket. The Biker’s Choice manual primary chain tensioner is available for most Harleys and many other motorcycles.
Twin Power’s Tension Reliever
If you’ve been struggling to keep your primary chain tensioned for your V-Twin motorcycle, consider getting a Tension Reliever Manual Primary Chain Adjuster. This tool is designed to solve many common primary chain tension issues and is available at your local Tucker Rocky/ Biker’s Choice dealer. The Twin Power Tension Reliever replaces the factory adjuster and offers up to 5/8 inches of free play in cold weather. Made from 6061-T6 aluminum, it features a 4140 steel adjusting screw and a 6/6 nylon shoe. Installation requires you to remove the outer primary cover to access the tensioner.
Most manufacturers include a manual primary chain tensioner in their motorcycles, but there are several options available for you to choose from. You can also purchase a universal replacement primary chain tensioner shoe to fit any bike. Regardless of which model you have, the Twin Power Tension Reliever will keep your chain properly tensioned and will prevent premature engine and transmission failure. The primary chain tensioner is an important part of your bike, and should never be left unattended.
Harley’s automatic primary chain tensioner
The Automatic Primary Chain Adjuster is original equipment on Harley-Davidson Dyna(r) and Softail(r) models. It eliminates the need to manually adjust the primary chain tension. It works by ratcheting the shoe up or down by one notch whenever the chain slacks. The automatic tensioner has its own drawbacks, however. Here are some of the drawbacks of Harley’s automatic primary chain tensioner.
