Show original supplier description

The USA Standard Gear ZP FSD60-3-35 is a robust steel spool engineered for high-performance applications within Dana 60 axles. Specifically designed for axles featuring 35 spline count, this spool is compatible with 4.10 gear ratios and numerically lower (e.g., 4.56, 4.88, 5.13). Its core function is to deliver unwavering 100% traction to both rear wheels simultaneously, ensuring maximum grip in demanding off-road or competition scenarios. Constructed from durable steel, this spool is built to withstand the rigors of extreme use. It is crucial to note that due to its nature of locking both wheels together, the USA Standard ZP FSD60-3-35 is explicitly not recommended for street-driven vehicles, as it can cause tire scrub, increased wear, and difficult handling characteristics on pavement. This component is intended for off-road racing, rock crawling, or other specialized applications where maximum traction is paramount.
