Product Spotlight: Superlift Black Diamond Coil Correction Kits for Jeep TJ Wrangler and Unlimited/LJ Rear Coils

Off-roading vehicles need a dedicated suspension system to help them overcome the many physical obstacles they encounter. One serious suspension flaw that lifted Jeep TJ Wrangler and Unlimited/LJ trucks suffer are that the rear springs are mounted in a "leaning forward" position and the coil system angles backward, away from its mounting position. This causes the coils to bow rearward when the Jeep is lifted and to especially bow during suspension compression. Due to the improper rear coil loading, ride height is lost and the spring rate gets softer, leading to less capable rear coils.   |   jeep Wrangler Tj coil Correction Kit The incorrect mounting of the rear coil systems makes the Wrangler less than optimal for off-road activity. During hill-climbing, the softer spring rate on the factory suspension causes too much weight to transfer to the rear, which makes the front of the truck lighter. When too much weight is transferred to the rear coils, the soft spring rate causes them to compress more, leading to the angled coils lying further down and causing the rear axle to move further back. The result of the increased rear load is the falling-over-backward feeling, which also implicates a reduction in the rear coils' capacities. The Black Diamond coil correction kit corrects lifted TJs' rear coils by putting them in their optimal upright position, which restores the spring rate. The kit includes weld-on frame brackets and replacement upper coil seats, allowing the rear coils to become as vertical as possible. Take a look at the comparison image: The corrected rear coil is located on the right. The kit components are precision-cut from quarter-inch-thick steel, and the coil brackets have been finished with a long-lasting black powdercoat.   |   jeep Wrangler Tj coil Correction Comparison To ensure the coils will always be in an upright position, the frame brackets have five adjustment holes. This allows the wheelbase of the Wrangler TJ and Unlimited/LJ to be increased by up to 2.0 in., but will keep the coils' compressions at an optimum level. The Black Diamond coil correction kit will work with any lift height and any brand suspension lift and comes with a limited lifetime warranty. . Source: Morr-Ink Press Release
