High-Horsepower Turbo Street Performance

Designed for high-horsepower street and strip builds, this direct-fit straight-cut gearset delivers ultimate strength and durability at an unbeatable price point. Engineered from high-strength forged steel, each gear undergoes heat treatment, cryogenic treatment, and shot peening to withstand the extreme torque loads of modern turbocharger setups.

The straight-cut tooth profile minimizes drivetrain friction and power loss, ensuring maximum power hits the pavement. Built with long-term reliability in mind, this set features serviceable engagement rings, allowing you to replace wear items individually rather than buying a full new gear—saving you significant time and money down the road.

Key Features & Benefits

  • Optimized Ratios (1st–4th):

    • 1st: 2.6

    • 2nd: 1.6

    • 3rd: 1.2

    • 4th: 0.9

  • Maximum Strength: Massive gear teeth made from forged, heat-treated, cryo-treated, and shot-peened alloy to reduce gear sheer under high turbo boost.

  • Reduced Drivetrain Loss: Straight-cut design offers lower rotational resistance and increased efficiency compared to OEM helical gears.

  • Cost-Effective Maintenance: Serviceable engagement rings mean cheap, quick overhauls without replacing full gear assemblies.

  • Direct-Fit Upgrade: Engineered to replace stock 1–4 gears while keeping full street usability with synchro engagement.

Compatibility & Synchro Specs

  • 1st–2nd Gears: Requires Triple-Cone Synchros

  • 3rd–4th Gears: Requires Dual-Cone Synchros (6-Speed)

  • Hub & Slider: Requires 6-Speed 3rd–4th Hub & Slider (Note: Will not function with 5-speed hub/slider setups).

⚠️ Important Installation & Clearance Notes

Due to the larger tooth profile and enlarged gear dimensions, proper clearance checks are mandatory prior to final assembly:

  1. Reverse Components: You must clearance the reverse actuator and reverse fork to ensure full clearance around the larger gears.

  2. Speed Sensor Clearance: For transmissions utilizing a front-mounted speed sensor (casing mounted, not on the differential), you must shim/clearance the speed sensor using a washer. Failure to space the sensor outward will cause the larger gears to strike the sensor magnet during operation.
