Product Information

The PRP Integrated Main Cap Engine Block Brace for Mitsubishi Evo 4–9 4G63 engines is designed to significantly improve bottom-end strength and stability in high-power and motorsport applications.

As 4G63 engines are pushed beyond factory limits, main cap walk and lower block distortion can become a serious reliability issue. This integrated block brace ties the main caps together, increasing rigidity through the crankshaft tunnel and helping maintain correct crank alignment under high cylinder pressure, sustained RPM, and aggressive boost levels.

Precision-engineered for serious performance builds, this brace is an essential upgrade for drag, circuit, and high-boost street Evo applications where durability and consistency are critical.

Key Features

  • Designed specifically for Mitsubishi Evo 4–9 4G63 engines

  • Integrated main cap brace design for maximum strength

  • Reduces main cap movement and block flex

  • Improves crankshaft stability under high load

  • Ideal for high-boost, high-RPM and motorsport builds

  • Precision engineered by Platinum Racing Products

Fitment Notes

  • Suits Mitsubishi Lancer Evolution IV–IX (4G63)

  • Engine machining and professional installation recommended

  • Intended for high-performance and competition use
