Track-proven to 2,000 horsepower, Sonnax Premium gears are an ideal choice when extra durability is needed at a reasonable cost in demanding applications. 1.80 Ratio Premium gear set 180S-K features premium-processed sun and pinion gears that are a big step up from standard case-hardened and tempered varieties. A top-quality material combined with a special heat-treating process results in gears with improved grain structure and stability that are tougher and more wear resistant.
- Top-quality sun and pinion gears deliver outstanding durability
- 12-Tooth billet drum flange is broached and matched to the sun gear for a precise press fit, no welding required
