The Maxtrac Suspension 4-inch lift spindle is a cost-effective way to lift your 2WD wheel drive truck without breaking the budget. We do this by taking a factory height spindle and lowering the wheel hub position, which in turn raises the vehicle up while maintaining a factory-like ride and turning radius. By doing this, you eliminate the need to install expensive crossmembers that are labor intensive and require factory frame cuts. The spindles come with extended, DOT compliant, stainless steel braided brake lines.
