Sonic Racing Products Rear-mount Starter Driveline Packages are specifically designed for short track racing. These packages are ideal for any Late Model-type class that allows the use of small diameter clutches and flywheels, reverse-mount starters and aluminum bellhousings. Starting a MSRP of $1895, Sonic Rear-mount Starter Packages meet the budgets of most cost-conscious racers. Sonic Rear-mount Starter Packages benefit from many of the design features found in Tilton's successful UTGC Magnesium Monohousing Packages, mated to cost-effective manufacturing process and materials. The result is a quality, "no-frills" driveline package for the hardcore short track racer. Sonic Rear-mount Starter Driveline Packages include an aluminum bellhousing, clutch assembly and discs, 105-tooth flywheel, hydraulic release bearing and rear-mount starter. Features Aluminum Bellhousing: An incredibly rigid and strong bellhousing offering maximum ground clearance. Benefits from the same casting molds as Tilton's UTGC Magnesium Monohousing. Rear mounts starter for additional header clearance and improved weight distribution. Weighs 11. 4 lbs. 5. 5" Clutches: Offer excellent engine acceleration and deceleration characteristics through a low Moment-of-Inertia. Features a similar open clutch cover, pressure plate, and floater plate design as Tilton's OT-series clutch for uncompromised reliability. Available in 2 or 3-plate versions. 105-tooth 8. 92" Flywheel: Machined from top quality, preheat-treated billet 4140 steel. This results in a far superior and safer operation than competitor's riveted-on ring gears and stamped metal adapters. After machining, flywheels are given an additional surface heat treatment, greatly improving ring gear tooth life and reducing wear to the clutch friction surface. This flywheel also provides a lower Moment-of-Inertia than competitor's 110-tooth arrangement. Rear-mount Starter: Features a 1. 4 kW (2. 0 hp), 9-tooth pinion gear and proven gear reduction design. It is also directly interchangeable with Quarter Master rear-mount starters. Hydraulic Release Bearing: Mounts directly to the bellhousing and all clearances are preset from the factory. Once installed, bearing clearance will never need to be adjusted over the life of the clutch. Features the same seal and piston designs that have made Tilton bearings the choice for 24 Hour endurance racing where 20, 000 shifts in a single race is the norm.Pit Stop USA offers Sonic Rear-Mount Starter Driveline Package - 5.5" 3-Plate - Rear-Mount Starter - Fine Spline - SB Chevy V-8 (E) 10001 at low everyday prices.
