Sonnax Heavy-Duty Forward Sun Gears

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.)
