Product Overview
The JT Sprockets Steel Front Countershaft Drive Sprocket (Part #JTF1902.14) is a premium, competition-grade drivetrain component manufactured by the world's leading aftermarket sprocket brand, JT Sprockets. This 14-tooth front engine sprocket is engineered to transfer high-torque engine power directly from the transmission countershaft to the rear wheel hub via an industry-standard 520-pitch drive chain. Designed as a precise direct OEM replacement swap, utilizing this ultra-durable 14T steel gear setup ensures fluid power transfer, stable final-drive geometry, and maximum durability under heavy acceleration.
Technical Specifications
- Manufacturer: JT Sprockets
- Part Number: JTF1902.14
- Product Type: Drive Train / Front Countershaft Engine Sprocket
- Material: Premium SCM420/SCM415 chromoly steel alloy for absolute core hardness.
- Finish: Natural bead-blasted raw metal treated with specialized induction heat treatments.
- Size Profile: 14-Tooth (14T) tooth pattern configured exclusively for a 520 final drive chain pitch.
- Manufacturing Process: Advanced computer-designed (CAD) hobbing, milling, and drilling with precise hand finishing.
- Fitment Type: Direct OEM replacement slider matching original manufacturer transmission splines. [1, 2, 3, 4]
Key Features & Benefits
- Chromoly Steel Construction: Fabricated from top-tier structural steel alloy that resists structural bending, chipping, and face pocket wear under extreme high-torque racing conditions. [1, 2]
- Precision Hobbed Profile: Every single tooth is precision hobbed rather than cheap metal stamped. This achieves incredibly narrow assembly tolerances and fluid chain-roller interaction. [1, 2]
- Induction Thermal Hardening: Fully heat-treated and bead-blasted to dramatically lower material surface tension, helping it outlast traditional mild steel sprockets. [1]
- Drivetrain Longevity: Engineered to fit the transmission splines with micro-clearance accuracy, eliminating countershaft play to maintain linear power delivery and defend output shaft seals from stress-induced leaks. [1]
