Sonnax premium planetary assemblies are available in various configurations to meet different build requirements. The output shaft is available in the OEM length or short length, and the billet-machined drum flange in 12-tooth or 24-tooth. They are a big step up from standard case-hardened and tempered gears. Sonnax's top-quality racing gear material (SAE9310), combined with a freeze-tempering process (-150 degrees F), results in gears with improved grain structure and stability--tougher and more resistant to wear. Sonnax premium planetary sets are fully assembled and ready to install.

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.

Sonnax heavy-duty forward sun gears are direct replacements for all 31-tooth sun gears used in 2.84/1.55 ratio gear sets. Manufactured from 9310 heat-treated alloy steel, these gears are significantly tougher and stronger than OE or other aftermarket sun gears—and are the perfect option for demanding applications. These are the same sun gears included with Sonnax Smart-Tech direct drum and shaft kits (76656-01K) that combine high-strength direct drum with integrated intermediate stub shaft. (Can be used with stock-size shaft and drums for medium-duty or budget builds.)
