Description
Crafted in the USA, our 11 leaf springs offer a progressive rate that provides outstanding performance without breaking the bank. These premium springs come with essential features such as Teflon wear pads, tapered ends, and built-in safety double wraps on the mainspring. Additionally, catch stops prevent over-articulation when used with your Monster or Duck Tuff suspension system.
Included with your purchase are black polyurethane spring eye bushings and sleeves, enhancing durability and reducing wear, all at no extra cost. If shackle bushings and sleeves are needed, they are available separately.
For those looking to enhance their suspension further, optional upgrades include:
– Leaf spring and shackle mounting hardware
– Shackle bushings with sleeves
– Duff HD spring plates
– U bolts or HD U-bolts
– HD shackles
– Pinion shims
– Lift blocks
– Weld-on spring perches available in factory and 1″ built-in lift options
Understanding whether to choose medium or heavy-duty springs is crucial. The heavy-duty version ensures your Bronco sits level or slightly higher in the rear, accommodating additional weight without sacrificing ride quality.
Medium-duty springs are suited for Broncos with minimal rear accessories, while heavy-duty springs are ideal for well-equipped builds that may include larger fuel tanks or frequent off-road usage. For any towing requirements, the heavy-duty option is strongly recommended.
To achieve optimal ride height and driveability, we offer a variety of solutions, including lifted spring perches and lift blocks. Our new 1/2″ lift block allows for adjustments that enhance clearance for uncut lifted Broncos.
Installation requires that the double spring wrap be oriented towards the front of the Bronco for optimal performance.
