Gear-X components are absolutely the best of the best, in their line of products. The value is incredible and the materials, machining and quality of these gears and final drives is unsurpassed. You won't find a better quality product for the price anywhere. Manufactured from the finest forged chromoly steel and machined to exact tolerances, these gears will out perform and outlast any competing brands on the market. Designed for racing, tested and sold by racers!

The Gear-X Close Ratio Gear Set for the K-Series engine is designed as a drop-in replacement kit for up to 500hp.

Suitable for street and race K20 or K24 where very close ratio applications are required, such sprints, hill climbs, road race and drag race. Works well with a factory final drive, but is a spectacular performer when used with a 5.08 final drive. When a 5.46 final drive is used with this gear set, it is designed for very short-course racing or fast, short, autocross courses. It is not suggested using the 5.84 or 6.33 final drives with this close-ratio gearset.

      Worked with slight modification
      Had to slightly widen the holes in metal gasket to make it fit.
