SO-CAL is dedicated to bringing to the industry innovative new products so we've improved our front spring clamp to incorporate a bump stop that can protect your axle. The spring clamp design makes shimming for different numbers of leaves simpler. The bottom plate is easily removed and and changing out the bolts when a shorter clamp is needed is much easier than modifying U-bolts. The clamp comes with an aluminum spacer block which is used for tuning the ride height of the car.
