EK 630SHBZ Drag Race Chain 150L (10) (RAS)

EK 630SHBZ Drag Race Chain 150L (10) (RAS) is purpose-built for the demands of drag racing, where every inch of power transfer and every microsecond of timing counts. This is not a casual replacement chain—it’s a dedicated race-grade drive for high-torce engines, optimized to withstand brutal launches, rapid shifts, and track-day sessions where consistency matters.

Why choose this drag race chain

• 
  630-series design means heavy-duty construction capable of handling high horsepower and aggressive traction without sacrificing durability or reliability on the strip.
• 
  150L length provides flexibility for extended wheelbase setups and varied sprocket configurations, enabling precise chain tensioning and optimal wrap for peak power delivery.
• 
  SHBZ finish signals a specialized coating and treatment designed to reduce friction, resist corrosion, and extend service life under demanding racing conditions.
• 
  RAS designation marks a racing-focused build with tight tolerances and robust components engineered to deliver consistent performance across multiple passes.
• 
  Precision engineering with hardened pins and high-strength plates ensures minimal stretch, improved shift feel, and reliable continuity under high-load launches.

What this chain delivers on the track

For drag racing enthusiasts and professional racers alike, the EK 630SHBZ Drag Race Chain 150L (10) (RAS) translates raw horsepower into reliable, repeatable acceleration. Expect crisp engagement, reduced power loss through drivetrain friction, and a chain that stays within spec through the heat of a race day. The combination of size, coatings, and race-grade manufacturing provides a durable link system that resists the abuse of hard launches and rapid acceleration sequences common in quarter-mile and bracket racing.

Ideal use cases

• Dedicated drag bikes and race-prepped motorcycles that demand maximum traction and dependable power transfer.
• Long-wheelbase builds or sprocket configurations that require additional chain length without compromising tension.
• Track enthusiasts who push engines toward high RPM ranges and frequent, aggressive shifts.
• Maintenance-conscious racers seeking a chain with enhanced longevity under harsh racing conditions.

Practical considerations and best practices

• Use with compatible EK sprockets and a rivet-style master link designed for 630-series chains to ensure a secure, reliable connection.
• Follow a race-appropriate break-in and lubrication routine to maximize life and performance, especially during initial track sessions.
• Inspect for wear, stretch, and any signs of deformation after each race weekend, and replace as needed to maintain optimal power transfer and chain safety.
• Store and service in a clean environment; protect the SHBZ-coated surface from grit and moisture to preserve its friction-reducing benefits.

Who should consider this chain

The EK 630SHBZ Drag Race Chain 150L (10) (RAS) is tailored for riders who treat drag racing as a science—teams and individuals who chase consistency, peak performance, and predictable reliability across multiple passes.
