Hawks Motorsports offers our clients this 1978-1993 Ford Fox Body TREMEC TKX Manual-to-Manual 5-Speed Conversion Kit | 600 lb-ft Capacity | TRK-FOXBODY. This kit is designed for vehicles that already have a manual transmission and provides an upgrade path to the modern TREMEC TKX 5-speed overdrive transmission.

The TREMEC TKX delivers improved drivability, stronger performance capability, and improved highway comfort compared to original Fox Body manual transmissions. With a compact rounded case design, 600 lb-ft torque capacity, and the ability to support up to 7,500 rpm shifts, the TKX is built for street-driven performance vehicles, restoration projects, and modified Fox Body applications.

This manual-to-manual conversion kit helps retain the driving experience enthusiasts expect while adding modern overdrive capability. The TKX provides reduced engine RPM during highway cruising, reduced noise vibration harshness (NVH), and improved shift quality for everyday driving.

Important Fitment Notice: This listing is for manual-to-manual conversions. Vehicles originally equipped with an automatic transmission will require additional automatic-to-manual conversion components such as a bellhousing, clutch system, pedal assembly, hydraulic clutch components, and related hardware. Verify your vehicle configuration before ordering.

The TREMEC TKX is available in multiple gear ratio configurations to suit different driving needs.

TKX Gear Ratios:

• Wide Ratio: 3.27, 1.98, 1.34, 1.00, 0.72
• Close Ratio: 2.87, 1.89, 1.28, 1.00, 0.68 OR 0.81
