Mitsubishi Evo Billet Diff Cap – Crown Wheel Reinforcement Upgrade
🛠️ Strengthen Your Evo 6–9 Rear End — Billet Diff Cap for Crown Wheel Support
When pushing serious power through your Mitsubishi Lancer Evolution 6, 7, 8 or 9, the factory aluminium diff cap can flex under load — allowing crown wheel deflection that risks failure or gear damage. This CNC-machined Billet Diff Cap provides a serious upgrade in rigidity and alignment, ideal for high-torque street, track or drag builds.
Engineered by Milton Engine Developments, this precision billet component is designed to replace the factory cap and provide superior support to the ring gear under extreme load.
✨ Key Features:
- Billet aluminium construction – high strength and thermal stability
- Supports crown wheel under high torque loads
- Prevents cap walk and gear misalignment in high-RPM conditions
- Designed for Mitsubishi Lancer Evolution 6, 7, 8, and 9 rear differentials
- Precision-machined in South Australia
📦 Fitment:
- Mitsubishi Lancer Evolution VI (Evo 6)
- Mitsubishi Lancer Evolution VII (Evo 7)
- Mitsubishi Lancer Evolution VIII (Evo 8)
- Mitsubishi Lancer Evolution IX (Evo 9)
- Fits factory rear differentials with original caps
🔧 Installation Notes:
- Professional installation by a drivetrain specialist recommended
- Torque to factory specs or as per build requirements
