Description

If you're running a touring bike and want measurable power gains without a complete engine rebuild, the S&S Cycle 551 Series Gear Drive delivers. By eliminating timing chain lash and reversing the rear cam's rotation, this kit unlocks higher valve lifts and stronger low-to-midrange torque across the entire powerband. The precision of gear drive timing means you get consistent, repeatable performance—no more chain stretch robbing you of reliability or power.

This is a professional-level installation requiring machine work, specialized tools, and verification of critical clearances. But if you're committed to extracting real performance from your engine, the results justify the effort.

  • Material: 4130 chromoly construction
  • Fitment: Touring bikes only
  • Compression ratio: 9:1–9:9
  • Peak power band: 1,000–4,000 rpm
  • Installation type: Requires professional fabrication
  • Timing accuracy: Eliminates chain lash
  • Valve lift: Increased capability
  • Compatible with: Stock pushrods, springs, lifters
  • Included: Cams, inner/outer gears, bearings, gaskets, instructions
  • Material removal: Required from gear cover
  • Tools required: Hydraulic press, professional-level equipment
  • Pre-installation checks: Coil bind, valve clearances, piston clearance
  • Maintenance note: Replace cam bearings and gaskets
  • Characteristic: Increased valve train noise (normal)
  • Origin: Made in the U.S.A.
  • MPN: 330-0100
