Sonnax input carrier kits transform OE wide-ratio automatic transmissions into a close ratio for game-changing acceleration on the track. Manufactured and engineered for outstanding durability, these kits keep your engine in the optimal power band, while allowing a longer pull in first and second gears, improving consistency and performance. The input carrier gears are precision-ground to OE standards and feature thrust washers with a highly wear-resistant, PTFE-coated material, plus a thicker captured bearing. Lube channels direct oil to the pinion pins, and the carrier can be disassembled for inspection and service. Stay in the power band with Sonnax input carrier kits.
