Review on SuperSprings TSS 106 40 SumoSprings Trailer Spring by Brandon Vox

Item requires a minimum clearance between leaf spring top and caravan frame of 6 3/4" with optimal preload of 1/2". My unit has 5 1/2 inches of clearance, which would result in over 1 inch of preload. To install this unit I would have to purchase shorter screws, the ones supplied required using one of the spacers provided by SumoSprings. You need to look for other options. The quality of the product looked very good, just not for my device.
