This single leaf helper is rated for up to 2000 Pounds and improves tow/haul performance by levelling the vehicle. The step style spring easily installs on top of the factory leaf pack with just basic hand tools and does not require the loosening of any factory components. The installer can adjust the end U-bolts to tune the rate of the spring as well. This allows the spring to be adjusted to your specific load or even to let the vehicle be levelled left to right if the load is uneven.
