LS1 3.905″ PISTONS -10cc DISH 4.000″ ST 6.125″ ROD 1.115″ CH

Description

Maximize engine performance and reliability with pistons engineered to exact LS1 specifications. These pistons address common challenges in combustion efficiency and mechanical stress by delivering precise dimensions and tailored volume displacement.

The 3.905″ piston diameter ensures a perfect fit within LS1 engine cylinders, reducing friction and wear. This precision fit directly contributes to improved engine responsiveness and longevity.

The -10 cc dish volume modifies the piston crown to optimize compression ratios and combustion chamber shape, enhancing fuel burn efficiency and power output. This design reduces the likelihood of detonation and improves overall engine smoothness.

Constructed with a 4.000″ stroke and a 6.125″ rod length, these pistons maintain ideal rod-to-stroke ratios, balancing performance and durability. The 1.115″ compression height is engineered to maintain proper piston-to-valve clearance, avoiding interference and ensuring reliable operation at high RPMs.

Weighing 5.4430 kg per set, these pistons balance strength and weight to minimize reciprocating mass, which reduces engine vibration and allows quicker throttle response.

Measuring 30.50 cm in length and height with a 15.20 cm width, the physical dimensions are optimized for compatibility with LS1 engine components and standard block configurations, streamlining installation and reducing modification requirements.

Manufactured by JE Pistons, a brand recognized for precision forging and material integrity, these pistons are made from high-grade aluminum alloys that withstand high thermal and mechanical stresses typical of high-performance applications.

These pistons directly enhance combustion efficiency, mechanical reliability, and engine balance. Designed specifically for LS1 engines, they offer measurable improvements in power delivery and durability, making them an essential upgrade for serious engine builders.
