Some racers simply welded the spider gears to permanently lock them. These differentials have 6 planet gear sets, and as a result, can boast a significant increase in gear strength rating, fatigue life and impact load capability. Edmunds also has Ford F-150 SuperCab pricing, MPG, specs, pictures, safety features, consumer reviews and more. As traction declines though, it may send power towards other (normally unpowered) wheels. ... helping to reduce drag.
