JASPER-engineered pistons are forged (4032 alloy) compared to OEM's cast aluminum.
JASPER's pistons feature a fully machined and anodized crown to resist carbon buildup and provide a thermal barrier for higher heat strength and increased durability.
JASPER-designed pistons have a wider, coated piston skirt surface area to improve durability and promote scuff resistance. Pistons also include stronger ring lands to withstand high cylinder pressure.
Installation of our forged pistons and ring sets allows JASPER to block off the piston oilers, which improves oil pressure throughout the engine.
100% torque-plate honing of the engine block, utilizing a torque plate and specially designed ARP2000® bolts, provides cylinder wall geometry that matches the cylinder head as a complete running assembly for improved ring sealing.
Camshafts are machined to exact tolerances.
Cam bores are machined with a specially designed, coolant-fed Mazak machine.
These processes will maintain tight specifications on bore alignment, size, and surface finish.
100% installation of NEW intake valves utilizing a 21-4N material to eliminate valves from developing a mushroomed condition (thinning of the valve face and margin).
Intake and exhaust valves are NEW and fully nitrided for improved heat resistance and reduced valve guide wear.
100% live-run tested to verify proper compression, vacuum, and oil pressure.
100% tested intake and exhaust cam actuators to verify proper performance.
100% blacklight leak-tested to ensure the unit is leak-free.
