ICONs 2″ Rear Leaf Expansion Pack provides increased suspension lift and better ride quality for lifted 08-24 F-250/F-350 Super Duty pickup trucks. The Expansion Pack is designed to replace and improve the center leaves of the stock leaf spring pack while retaining the factory main leaf. This makes the Expansion Pack both cost-effective and an easier installation as it doesnt require complete removal of the leaf spring main leaf from the spring hanger and shackle. The additional leaves included in the pack are designed to optimize ride quality and reduce axle wrap compared to lift blocks. The design also shifts the overload transition point to improve small bump compliance.Additional Attributes:GTIN:00840103423036Material:SteelColor:BlackSuspension Grade Type:PerformanceLeaf Quantity:7Axle Orientation:RearHelper Spring:yesAxle Modification Needed:NoBushings Included:NoMounting Hardware Included:NoGrade Type:PerformanceU Bolts Included:NoMaximum Lift:2AAP_UDA_12:EAAAP_UDA_22:1AAP_UDA_4:55Add-On Part:37003 99-10 FSD REAR 15 U-BOLT KITCalifornia Proposition 65:WARNING: This product contains chemicals known to the State of California to cause cancer, and birth defects or other reproductive harm.Extended Information:Emissions :Emissions Compliance ExemptLife Cycle Status:Available To OrderPackaging:Quantity of Each:1.0Package UOM:EADimension:54.0000 x 48.0000 x 10.0000 inchesWeight:85.0000 PGPDF:I168507_REVA
