Chain Kit for 4 Speed Big Twin, 1973-85 Shovelhead & EVO

Chain kit includes everything needed to REFRESH your 4 Speed Bike to a heavy duty 530 O-ring chain:

22T Front Sprocket and 51T Rear Sprocket is the stock gearing.

KIT INCLUDES:
Transmission Sprocket

• Heat Treated Steel
• 22, 23 or 24 Tooth

Steel Rear Wheel Sprocket

• Full thickness for 530 Chain, beware of other thin .25 thickness sprockets out there.
• Steel Sprockets last longer than aluminum sprockets and are ideal for high load situations (Burnouts, Wheelies, High Horsepower Engines)
• Black Powdercoat Steel or Chrome plated Steel
• 48, 49, or 51 Tooth Available

Transmission Nut Lock Plate

Transmission Super Nut

Grade 8 Hardware for rear sprocket

Chain Info:

530 O-Ring(BMOR) Chain

• 9,700lbs Tensile Strength
• Includes Rivet Master Link
• Component designs optimized with computer analysis provides higher tensile strength.
• Specially controlled heat treatment means tougher material.
• Reinforced roller offers higher impact resistance and longer durability.
• Available in Natural, Black, Gold or Black/Gold
  

530 X-Ring (BMXR) Chain

• 9,700lbs Tensile Strength
• Offering 1.5 to 2x longer wear resistance than regular O-ring chains.
• Each refined component, designed with computer analysis, provides higher tensile strength.
• Specially controlled heat treatment means tougher material and more durability.
• Quad seal ring and reinforced pin and roller provide superior wear resistance, higher impact resistance and fatigue strength.
• Quad seal ring offers less friction, which minimizes power loss, almost half that of standard O-ring chain.

530 High Strength BMZR Chain- Recommended for all baggers

• 11,200lbs Tensile Strength
• Includes Rivet Master Link
• Specifically developed for today’s high-performance sport machines.
• High-quality components coupled with a factory-greased seal ring ensures superior rigidity.
• High-tensile steels used throughout the chain components; larger pins
  mean loads spread out over wider area, resulting in longer life and more
  strength.
• Specially controlled heat treatment means tougher material and more durability.
• Available in Chrome, Black, Gold or Black/Gold

530 EK 3D Chain- High Strength, Recommended for all baggers

3D
parts are precisely manufactured, leading to a greater improvement of
transmission efficiency, better acceleration and efficient engine work.
Features an original special plate with a lightening hole. EK creates a
hole on both ends of a pin to lighten the chain without weakening the
plate according to computer analysis. The edge-cut inner plate reduces
friction and realizes smooth engagement with sprocket. This plate
enables the chain to be light, removes mud from the hole and dissipates
heat effectively.

• 11,400lbs Tensile Strength
• Includes Rivet Master Link
• Reduced friction
• Chromium carbide pin with lighten hole in end
• Inner plate with lighten hole
• Dimpled outer plate.
• QX-2 ring
