Timbren Suspension Enhancement Systems

Timbren Suspension Enhancement Systems resolve your suspension problems. Timbren SES kits will improve your load-handling, make it easier to haul heavy loads, and eliminate sag and sway. They're easy to install and maintain! Simply bolt on the kit—no drilling, no air lines to route—and you're ready to roll with high performance and peace of mind. The patented Aeon hollow rubber springs cushion and absorb road shocks and automatically adjust to uneven loads and road conditions. You'll enjoy improved roll stability and reduced sway, unlike with the mediocre trailer suspensions and softer ride quality of today's trucks and trailers. Your truck, van, and SUV are designed for best performance under ideal road and load conditions—but in the real world, to tackle the imperfect, you need a Timbren Suspension Enhancement System. Order the kit designed to fit your year, make, and model application.

Chevrolet Performance L8P 6.6L 400 C.I.D Engine Assemblies

By combining the large-displacement and heavy-duty elements of the L8T 6.6L engine and a unique camshaft based off the Corvette Stingray's high-revving LT2 V-8, Chevrolet Performance engineers have created the all-new L8P 400 c.i.d. Performance crate engine. Rated at 523 hp and 543 lbs.-ft. of torque, it offers your project a unique and naturally aspirated combination of big-displacement torque and high-rpm horsepower. The L8T 6.6L foundation is the same high-strength, big-displacement engine found in the Silverado HD from 2020 to present day, featuring a forged steel crankshaft and high-strength components. Additional features such as oil-spray cooling for the pistons and a cast iron, long-skirt cylinder block with 6-bolt, cross-bolted main caps contribute to the engine's strength and durability. The new L8P builds on that with a unique, upgraded valvetrain featuring performance-oriented valves and springs, along with a unique camshaft that is based off the Corvette Stingray's LT2 engine. It has a non-active fuel management profile and more duration than the L8t's camshaft. It's the best of both engines: the largest displacement in the LT family and the power-building attributes of the Corvette camshaft. Put it to work in your project. Fast Facts: * Displacement: 400 cu. in. (6.6L) * Bore x Stroke: 4.06 in. x 3.86 in. * Crankshaft: Forged steel * Pistons: Hypereutectic aluminum * Compression ratio: 10.8:1 * Cylinder heads: Rectangular port D/I with 59.02cc chambers * Camshaft type: Billet steel hydraulic roller * Camshaft duration: 218 degree intake/231 degree exhaust at .050 in. * Fuel delivery: Direct injection with high-pressure pump * Horsepower: 523 at 5,800 rpm * Torque (lbs.-ft.): 543 at 4,800 rpm * Engine type: Gen V small block V-8 direct injection spark ignition * Block: Cast iron with 6-bolt no Dula main bearing caps * Connecting rods: Forged powder-metal * Valve lift (in.): 0.549 intake / 0.549 exhaust * Rocker arms: Investment cast roller trunnion * Rocker arm ratio: 1.8:1 * Intake manifold: Composite * Throttle body: 87mm diameter (single-bore) * Fuel delivery: High-pressure direct injection (2,175 psi / 150 bar) * Recommended fuel: Premium pump * Ignition system: Coil-on-plug * Maximum recommended RPM: 6,000 rpm * Reluctor wheel: 58X * Balanced: Internal * Note: Use with the new engine control kit, P/N 19435524, which includes a programmed controller, wire harness, pedal, oxygen sensors and mounts, MAD, fuel line pressure sensor and fuel pump power module.
