Sonic Rear-mount Starter packages have been designed specifically for the short track racer. They are the most modern rear-mount starter packages on the market, offering the latest technology in driveline components. These packages provide great value, exceeding the performance and reliability of packages from other manufacturers.
Features:
• Aluminum Bellhousing: Rigid design eliminates power-robbing driveline flex. Offers maximum ground clearance. Blueprinted for accurate alignment. Weight: 11.4 lbs.
• 5.5" MACH II Clutch: Low inertia offers excellent engine acceleration and deceleration. The clutch features an open cover design and is assembled with quality components for the highest levels of reliability. Available in 2 or 3-plate versions.
• Flywheel: 105-tooth. Machined from heat-treated 4140 steel. Offers a far superior and safer operation than competitor's riveted-on ring gears and stamped metal adapters. Its smaller diameter, when compared to competitor's inferior cover-mounted ring gear design, offers reduced inertia for maximum engine performance. After machining, they receive an additional surface heat-treatment that greatly improves ring gear life and reduces wear to the clutch friction surface.
• Starter: Rear-mount. 1.9 hp motor and gear reduction provides quick, dependable starts. They are also interchangeable with competitor's rear-mount starter.
• Hydraulic Release Bearing: Mounts directly to the bellhousing. All clearances are preset from the factory. Once installed, bearing clearance will never have to be adjusted over the life of the clutch. Monoseal design provides maximum reliability.
