Black finish without caps, steel body with internal reservoir and gas-charged damping for consistent performance on the road.

• Extended Length: 279.40 mm (11.00") measured centre to centre

• Duty: heavy duty — recommended for motorcycles frequently used near the manufacturer's maximum load
• Material: solid steel, black finish
• Damping Method: gas charged; internal reservoir
• Origin: made in the United States

Before installation, check the travel and clearances (swingarm, exhaust, chain/belt guard, tyre). On certain XL models ('86–'15), a chain guard adjustment or spacer may be necessary. Some shocks in the range are road legal: check the latest certificate for the updated list.

Ideal for riders seeking sharper handling without extravagance: stiffness suited for heavy loads, simple spring adjustment, and a discreet matte black look to remain consistent with a classic Sportster or touring aesthetic.
