Superlift offers two styles of leaf springs to choose from. Standard springs yield a ride firmer than stock springs. These should be chosen for moderate to heavy-duty use when a winch, big block or diesel power plant is present, or if your rig is used for hauling/towing. 

Brake Lines

With the Superide line, spring rate has been reduced as much as possible to emphasize suspension travel and a more compliant ride. The design elements can include thinner leaf material, tapered leafs and/or spring inserts.

Steering arm recommended for lifts 4" and higher.

Kits use rear blocks. Systems use either 52" or 56" rear leaf springs.

SKYJACKER has developed and engineered SOFTRIDE technology leaf springs for the earlier generation of Chevy and GMC vehicles (1967-87). The SOFTRIDE technology produces the highest quality of leaf spring systems the industry has ever known. 

Softride springs manufactured by Skyjacker use tapered leaves to yield a lower spring rate and better travel, Teflon wear pads to help reduce interleaf friction, a "bolt" style clip to reduce leaf friction and shotpeening to compress the steel and increase its tensile strength. 

Kits use a rear block and/or add-a-leaf to accomplish the rear lift and Systems using rear leaf springs. Shocks & steering correction purchased separately.

Tuff Country offers 2 types of leaf springs. The EZ Ride springs are a softer spring rate for more suspension action and a softer ride. The heavy duty springs are slightly stiffer and have a higher load capacity for vehicles with heavy bumpers, winches or snow plows. The EZ Rides can be used for heavy duty applications for better flex but you will have less ride height due to the weight and reduced spring life.
