S&S Cycle Easy Start 585 Camshaft Kit, 106-5299, Chain Drive Big Twin 1999-2006
Regular price $540.95 USD
Category:
Upgrade compatible Big Twin engines with the S&S Cycle Easy Start 585 Camshaft Kit, part number 106-5299. Designed for 1999-2006 Big Twin models, excluding 2006 Dyna applications, this bolt-in camshaft kit helps make starting easier by temporarily reducing crank compression during initial cranking. As engine speed increases, the centrifugal compression release lobe retracts, allowing the engine to operate with full compression and without sacrificing performance once running.
The S&S Cycle 106-5299 camshaft kit is designed for 88-106 cubic-inch engines with compression ratios from 9.7:1 to 10.5:1, as well as 106-124 cubic-inch engines with compression ratios from 9.0:1 to 10.0:1. It is engineered to deliver strong horsepower and torque gains beginning at approximately 3,000 rpm and continuing through the upper operating range. Recommended performance ranges are approximately 3,500-6,000 rpm for 88-103 cubic-inch engines and 2,200-5,000 rpm for larger engines.
This complete kit includes the S&S Cycle camshafts, gear cover gasket, bearings, retaining ring, O-ring, thread-locking compound, and installation instructions. The bolt-in design supports a straightforward installation when used with compatible applications, while the included components help provide a convenient solution for performance-focused engine builds. Made in the USA, the 106-5299 camshaft kit is intended for installers familiar with performance engine assembly and setup. Before installation, verify coil bind, valve-to-valve clearance, and valve-to-piston clearance. This kit is not compatible with models equipped with OEM compression releases.
Features:
- Easy Start Design: Reduces crank compression during starting, then centrifugally retracts the compression release lobe as rpm increases.
- Full-Compression Operation: Allows the engine to run with full compression after startup without a performance loss from the compression release system.
- Engine Compatibility: Designed for 88-106 cubic-inch engines with 9.7:1-10.5:1 compression ratios and 106-124 cubic-inch engines with 9.0:1-10.0:1 compression ratios.
- Performance Range: Provides substantial horsepower and torque increases from approximately 3,000 rpm through redline.
- Bolt-In Installation: Designed as a bolt-in camshaft kit for compatible Big Twin applications.
- Complete Kit: Includes camshafts, gear cover gasket, bearings, retaining ring, O-ring, thread-locking compound, and installation instructions.
- Application: Fits 1999-2006 Big Twin models except 2006 Dyna applications.
- Made in the USA: Manufactured by S&S Cycle in the United States.
- Installation Requirement: Verify coil bind, valve-to-valve clearance, and valve-to-piston clearance before installation.
- Compatibility Warning: Not intended for models equipped with OEM compression releases.
