Introducing the new adjustable Linkage Guard from Fastway. They teamed up with the suspension pros at Stillwell Performance to design a product that replaces the linkage arm with a hybrid guard and adjustable suspension link. "Pro" version is a closed design for improved strength over the "Trail" model. Adjustment: Four adjustments available from stock out to 2 mm. Improves front end steering and cornering. Helps with rear wheel traction. Can lower seat height down 1/2 an inch at 2 mm setting. Protection: Machined from a solid block of 6061 aluminum. Weighs only about 6.7 ounces over stock link. Shaped to deflect blows away from the linkage. Protective 'hard-black' anodized finish. Dual heavy-duty 20 mm needle bearings with dust seals installed.
