The ARC DJ-1028 Racer Series kit is a high-performance upgrade for GX240, GX270, and Predator 301cc Hemi engines, designed for increased horsepower, higher RPM capability, and aggressive racing applications. Includes billet flywheel, billet rod, camshaft, and valvetrain components. See full product details below.
The ARC DJ-1028 Racer Series kit is designed for GX240, GX270, and Predator 301cc Hemi engines where maximum performance, higher RPM capability, and aggressive power delivery are the priority. This kit is built for racing and high-output applications, making it a step above mild performance upgrades.
These big block engines produce significantly more torque than small block platforms, which increases stress on internal components. Upgrading to billet flywheels and connecting rods is critical to safely handle higher RPM and prevent catastrophic engine failure under load.
The included performance camshaft and upgraded valve springs increase lift and duration, allowing the engine to move more air and fuel. This results in stronger acceleration, improved throttle response, and increased top-end power.
Performance kits for GX240/GX270/301 platforms are commonly built around billet rotating components and aggressive cam profiles to support higher RPM and competitive racing use.
Disclaimer: Some parts may need clearancing to fit.
