COMPSTAR SBC 3.480 STROKE, 350 MAINS, 2.100 PINS, 4340

Description

Optimizing engine performance starts with a crankshaft designed for strength and precision. The COMPSTAR SBC crankshaft offers a critical upgrade with its 3.480-inch stroke, allowing enhanced piston travel that translates directly to increased torque and horsepower. This component is engineered specifically for small block Chevy engines, ensuring compatibility and performance consistency.

Constructed from 4340 forged steel, the crankshaft delivers superior tensile strength and fatigue resistance. This material choice means the crankshaft withstands high RPMs and heavy loads without deformation, increasing engine reliability and lifespan. At 24.5 kilograms, the weight balances durability with manageable rotational mass, supporting quicker engine response.

• 3.480-inch stroke: Extends piston movement for greater displacement and power output, essential for performance builds.
• 350 mains and 2.100 pins: Provides robust bearing surfaces and pin dimensions, improving crankshaft stability and reducing wear under stress.
• 4340 forged steel: Ensures maximum strength and resistance to fatigue and stress fractures, enhancing durability in high-performance applications.
• Dimensions (95.30 cm length, 27.90 cm width and height): Confirmed sizing guarantees precise fitment in SBC engine blocks with no modification needed.

Each dimension is tailored for optimal balance and fit, minimizing vibration and mechanical losses during operation. The 2.100-inch pin size accommodates high-performance connecting rods, supporting aggressive engine builds without compromising reliability. The 350 main journals provide a solid foundation, maintaining crankshaft alignment and smooth rotational dynamics.

Designed and manufactured by Callies, a leader in high-performance crankshafts, this component meets stringent quality standards with meticulous forging and machining processes. The COMPSTAR SBC crankshaft is ideal for engine builders targeting improved torque curves and long-term durability under demanding conditions.

Equip your SBC engine with this precision-engineered crankshaft to realize measurable gains in power and engine longevity. Its specific stroke length, material composition, and journal sizing combine to deliver a reliable core component for serious engine enhancement projects.
