Armored Attitude Adjuster
If you have a 2006 or later Dyna, or a 2007 and later Softail or Touring bike, Bert Baker says that "you know the issues that come along with the stock auto chain tensioner. At the first moment that the chain has any slack in it, the auto tensioner ratchets the shoe up another notch.
"Now one notch is not going to be an issue, but the tightening never stops, and this causes several problems. The BAKER manual chain adjuster is stronger than the original and prevents damage to the motorcycle's left-side motor case bearings, inner primary bearings, clutch hub bearings, and transmission output gear bearings."
This Baker manual chain tensioner allows you to set the chain to the proper 5/8" 7/8" (cold) freeplay, and never have to worry about it being too tight.
The chain shoe is machined from Nylon 66, the active plate and back support plate is investment cast with 4130 steel. It has 28% finer teeth spacing (compared to 2001-06 chain adjusters) for more accurate adjustments - the chain adjustment method is same as 2001-06 style stock 'L-Bracket' adjusters.
Bert says that this design increases torque by 3.42 ft/lbs, reduces primary noise, helps prevent damage to the primary and improves motor bottom end and inner primary race bearing durability.
It is designed for 2006-later Dyna models; 2007-2017 Softail models and 2007-later Touring models. "The Armored Attitude Adjuster is an excellent solution for any non-racing application. We offer this chain adjuster for fitment with stock outer primary covers. I recommend checking the primary chain tension at the 500-mile interval and then after every 5000 miles, and you should replace the chain if cannot be adjusted properly."
