Rather than replace all of the parts that you already own, we made our adjuster work with existing components. Weld the adjuster to the frame of any underslung frame car in place of the old non-adjustable mount. Move your clamp on mount to its normal height and you will have 1-1/2" of easy adjustment in either direction. Larger adjustments may still be made by moving the clamp. To make easy adjustments use a 3/8" drive extension and ratchet to turn the internal screw to raise or lower the outer sleeve. Weights only 5.5 lbs. Accepts a 1-3/4" panhard clevis. 21" overall length
