RK Chain GB520EXW-108 520 Series Gold XW-Ring Chain 108 Link

The RK Chain GB520EXW is an XW-sealed chain and is the best high-speed, extreme heat performance off-road and ATV chain available today. This premium quality 520 XW-Ring chain features a tensile strength of 8,500 pounds per foot, making it suitable for applications up to 750cc off-road motorcycles and ATVs.

Advanced XW-Ring Technology:

• RK's XW-Ring seals utilize triple barrier grease protection plus anti-debris technology
• The XW ring has six sealing points, as well as two stabilizers that prevent the ring from turning under extreme load
• This avoids the loss of lubricant under all conditions - the service life is extended by up to 50% compared to an O-ring chain
• EXW was designed to handle ATV swingarm movement and increased torque stresses and wears 1.7 times longer when compared to O-ring chains

Thermal Protection Design:

• EXW chains feature special thermal crack resistant sideplates to protect against thermal cracking
• Thermal cracking can result from debris or components impinging the chain's movement, causing the chain to quickly heat up and cool down in rapid succession, which over time can reduce the strength of the chain

Premium Construction:

• Metal components are made from a specialized high carbon steel alloy that is shot peened, heat treated, and pre-stretched
• Anti-corrosion, gold tinted surface treatment
• Weight: 3.36 pounds per 100 links
• 108 links included with connecting link
