Product Title

Adjustable Billet 6061-T6 Aluminum Cam Gear | 2JZ-GTE & 2JZ-GE

Description

CNC-machined 6061-T6 billet aluminum adjustable cam gear for Toyota 2JZ engines. Eliminates OEM cast gear failure at high RPM. Direct B2B factory supply for engine builders.

Adjustable Billet 6061-T6 Aluminum Cam Gear | 2JZ-GTE & 2JZ-GE

A precision-machined Toyota 2jz cam gear should be used in place of the brittle OEM cast-iron sprockets. This adjustable unit, made especially for high-horsepower engine designs, guards against timing drift and gear cracking under high-RPM harmonics, excessive belt strain, and extreme valvetrain loads.

Key Technical Specifications

Material	Aerospace-grade 6061-T6 Billet Aluminum (Inner Hub and Outer Ring).
Hardware	5x ARP Grade 8 stainless steel locking bolts.
Adjustment Range	±10 degrees of camshaft timing adjustment (Advance/Retard) with laser-etched 1-degree mechanical increments.
Surface Finish	Type II Hard Anodized (Outer gear teeth hardened to 60 Rockwell C for extreme belt wear resistance).
Tolerance Control	Concentricity runout and gear pitch strictly held under ±0.01mm.
Weight	340g per unit (Providing a 40% reduction in rotational mass compared to the OEM cast gear).

Detailed Engineering Insight

The factory 2JZ cast cam gears become a severe mechanical liability when subjected to the aggressive ramp rates of aftermarket camshafts and stiffened dual valve springs. Operating as a specialized billet cam gear Toyota 2JZ manufacturer, RCH Precision engineered this structural upgrade to counteract the intense torsional vibration that causes OEM gears to fracture at the hub. By utilizing a solid 6061-T6 billet construction, this aftermarket cam gears for 2JZ engine increases tensile strength to 310 MPa while significantly lowering the moment of inertia.

The five-bolt locking mechanism guarantees zero slipping of the adjustable hub, ensuring your dialed-in valve overlap remains permanently locked during 9000+ RPM track sessions. For B2B wholesale buyers and tuning shops, sourcing a high quality Toyota 2jz cam gear is critical for tuning consistency; our ISO9001:2015 certified facility ensures strict batch-to-batch metallurgical integrity. The outer gear teeth are precision-hobbed to match the exact pitch of the timing belt, reducing operating friction and preventing premature belt degradation. Built for professional motorsport applications, this Toyota 2jz cam gear is dynamometer-tested to withstand valvetrain stresses exceeding 1,500 horsepower.
