FAQs
What mini spool works best for s10?
For a Chevrolet S10 truck featuring a GM 7.5 inch 10-bolt rear differential with 28 spline axles, the Motive Gear MS7.5-28 mini spool is an excellent choice. It replaces the stock spider gears inside the factory open carrier to provide permanent traction. Always verify your truck's specific axle spline count and differential size before purchasing.
Can this mini spool be used on a daily driven street vehicle?
Mini spools are primarily designed for dedicated off-road vehicles, drag racing cars, and track applications because they permanently lock the axles together. On daily driven street vehicles, a locked rear axle can cause tire chirping, accelerated tread wear, and chirping noises while turning tight corners. For regular street driving, a limited slip differential is usually preferred.
Does this product fit a GM 8.5 inch rear differential?
No, this specific model is engineered exclusively for GM 10-bolt rear ends with a 7.5 inch ring gear diameter and 28 spline axles. It will not fit larger 8.5 inch differential carriers. Please check your vehicle's service manual or axle housing codes to confirm compatibility before ordering.
