PBI Sprockets .000 Inch Offset 33 Spline 530 Transmission Sprocket for Harley Big Twin Sportster Buell

PBI Sprockets .000 Inch Offset 33 Spline 530 Transmission Sprocket for Harley Big Twin Sportster Buell

For builders and riders who demand exact drivetrain geometry, PBI Sprockets’ zero-offset transmission sprocket opens up fitment possibilities that standard offset options simply cannot address. The result is a drivetrain that lines up precisely how your build requires, backed by the same long-term reliability PBI is known for across their entire transmission sprocket lineup.

Key Features

• Available in 23 and 24-tooth configurations to suit your final drive ratio requirements
• Zero offset design for flush seating against the main shaft bearing — ideal for custom and narrow-profile drivetrain builds
• CNC-machined to exacting tolerances for consistent fit and reliable power transfer
• Case hardened for superior wear resistance under sustained high-load conditions
• Electroless nickel plated for corrosion resistance and enhanced lubricity across the chain interface
• Drilled and tapped to accept the late-model lock plate — lock plate available separately
• Compatible with .530 pitch chain systems

Fitment Notes

• 1986-1993 Big Twin models require an additional spacer, seal, and O-ring for proper installation — consult your factory service manual for the correct components before proceeding
• Offset measurement is taken from the face that rests against the main shaft bearing to the inside of the teeth — this sprocket seats flush with zero outboard displacement
• Verify chain line alignment carefully before installation, as zero offset may require adjustment to rear sprocket positioning depending on your specific build configuration
• Select tooth count based on your desired final drive ratio before ordering — gearing changes affect both acceleration and top speed characteristics
• Review the Fitment tab for the complete year and model breakdown
• 86-93 Big Twin models must use OEM #33344-94 (SPACER), OEM #12067A (SEAL), and OEM #11165 (O-RING)
