VW 2.0TFSI EA113 Golf 5 GTI Billet Kurbelwellenrad

Billet Crankshaft Timing Gear – VW 2.0 TFSI EA113 (Golf 5 GTI, S3 8P, Cupra, etc.)

Maximum Safety & Performance for Your TFSI Engine

This precision CNC-machined billet crankshaft gear made from high-strength 42CrMo4 steel is the perfect upgrade for a known weakness in VW and Audi 2.0 TFSI EA113 engines: the crankshaft-to-gear interface.

Especially in tuned engines with more than 500 HP, the OEM gear often loosens – risking catastrophic engine damage.

OEM Gear Problems:

• Keyway shears → crankshaft damage
• Timing belt slackens → timing shifts
• Valves collide with pistons → engine failure
• OEM gear too soft → not suitable for high torque

Solution: Billet Gear from 42CrMo4

• Machined from solid billet – no casting
• Material: 42CrMo4 – high tensile alloy steel
• Handles extreme tensile and compressive forces
• Suitable for engines spinning over 9,000 RPM
• Designed for 500+ HP performance builds
• Allows higher torque at crank bolt without distortion
• Race-proven, precise and durable

Technical Specs:

• Fits: VW Golf 5 GTI, Audi S3 8P, Seat Cupra (EA113 TFSI)
• Precision fit to crankshaft – no play or loosening

Conclusion: Must-have upgrade for any high-power TFSI engine – reliable, race-proven, and engineered for extreme performance.
