Durable, lightweight component
Durable, lightweight components such as titanium intake valves and connecting rods coupled with a forged-steel crankshaft make the LS7 engine incredibly robust. The standard 10.5-quart, dry-sump oiling system distributes pressurized oil from an external reservoir to protect vital components under high-g driving conditions.
The LS7 is mated to a TREMEC TR6060 6-speed manual gearbox that features close-ratio gearing - optimized for the engines power characteristics. The TREMEC is coupled with a 5.1:1-ratio short-throw shifter to ensure quick and precise feeling shifts.
Power is distributed to the rear wheels via a limited-slip differential, which features a helical gear set rather than traditional clutch packs. This continuously adjusts torque bias allowing drivers to confidently lay down more power to get through corners faster. Coupled with the Performance Traction Management (PTM) system, drivers can adjust the level of throttle and brake intervention to match their capability and driving environment, essentially making PTM custom to each driving situation.
Z/28 features a cooling system designed for the track ? standard. This incorporates the dry-sump oiling system for the LS7, which connects to an integral liquid-to-liquid cooling system for engine oil. Another liquid-to-liquid system provides cooling for the transmission and differential.
