Pro Shaft Rocker Kit LS3 1.70/1.70 AFR Mongoose

The Pro Shaft Rocker Kit LS3 1.70/1.70 AFR Mongoose is a high-performance rocker arm assembly designed for serious LS3 engine builders and track enthusiasts. This precision-engineered component enhances cylinder head performance by optimizing valve lift and duration characteristics, making it ideal for competitors, drag racers, and street performance builders.

The kit features a 1.70/1.70 rocker arm ratio that is specifically calibrated to deliver optimal valve overlap and lift characteristics across the RPM range when paired with AFR Mongoose heads on an LS3 platform. JESEL's Pro Shaft design incorporates precision-ground shafts and hardened steel rocker arms with needle roller bearings, minimizing friction and ensuring consistent valve actuation under extreme load conditions.

Engine builders integrating this Pro Shaft Rocker Kit with AFR Mongoose heads on LS3 platforms will benefit from improved valve control and repeatability across consecutive heat cycles. This makes it an excellent choice for high-performance applications, including turbocharged, supercharged, and naturally aspirated setups.
