This system eliminates the factory rake for a balanced stance while improving ground clearance to take on uneven terrain and off-road challenges with confidence. Performance-Driven Components: The kit includes a set of durable front coil springs for enhanced ride height without sacrificing comfort or performance. Application-specific 7-degree C-bushings and a track bar drop bracket maintain proper geometry and alignment, ensuring a factory-like ride quality even after lifting. Rear Lifted Leaf Springs for Strength and Support: Engineered for dependability, the included rear leaf springs are double-tapered and feature Teflon pad inserts to improve ride comfort while offering consistent lift and added load support. Premium N3 Shock Absorbers: This kit features Rough Country's nitrogen-charged N3 shocks, precision-tuned with a 10-stage variable valving system, 18mm piston rods, and fast-cooling 54mm shock bodies for enhanced off-road handling and smooth highway ride quality. Ready for 35-Inch Tires: Gain the clearance needed to run up to 35\" tires, giving your truck a more aggressive profile and increased off-road capability, all with proper wheel backspacing. Built to Last: Backed by Rough Country's Limited Lifetime Replacement Warranty, this 4\" Ford Suspension Lift Kit combines rugged durability with confidence-inspiring performance, on and off the road.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eImproved Ground Clearance:\u003c\/strong\u003e Gain the extra height needed to confidently tackle uneven terrain, obstacles, and off-road challenges.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront-to-Rear Leveling:\u003c\/strong\u003e Eliminates the factory rake for a more aggressive, balanced stance and improved handling dynamics.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Lifted Leaf Springs:\u003c\/strong\u003e Includes application-specific rear leaf springs designed to provide dependable lift, load support, and long-lasting durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits 35-Inch Tires:\u003c\/strong\u003e Provides the clearance needed to run up to 35\" tall tires for a more aggressive look and better trail capability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes N3 Shock Absorbers:\u003c\/strong\u003e Equipped with Rough Country's premium N3 shocks for improved ride quality and off-road performance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall time:\u003c\/strong\u003e 5-7 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront components:\u003c\/strong\u003e Lifted Coil Springs Track Bar Drop Bracket 7 Degree C-Bushings Hardware\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear components:\u003c\/strong\u003e Lifted Leaf Springs U-Bolts Hardware\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTire info:\u003c\/strong\u003e 35x12.50R15:Factory 15:5x5.5:-:-;35x12.50R15:15x8:5x5.5:-19:-;35x12.50R15:15x8:5x5.5:-18:-;35x12.50R15:15x10:5x5.5:-39:Trimming Required;35x12.50R16:16x8:5x5.5:-12:-;35x12.50R16:16x8:5x5.5:-6:-;35x12.50R17:17x8.5:5x5.5:+0:-;35x12.50R17:17x8.5:5x5.5:+1:-;35x12.50R17:17x9:5x5.5:-12:-;35x12.50R17:17x9:5x5.5:+0:-;315\/70R17:17x9:5x5.5:+0:-;35x12.50R17:17x9:5x5.5:+1:-;315\/70R17:17x9:5x5.5:+1:-;35x12.50R18:18x9:5x5.5:-12:-;295\/70R18:18x9:5x5.5:-12:-;35x12.50R18:18x9:5x5.5:+0:-;295\/70R18:18x9:5x5.5:+0:-;35x12.50R18:18x9:5x5.5:+1:-;295\/70R18:18x9:5x5.5:+1:-;35x12.50R18:18x10:5x5.5:-25:-;295\/70R18:18x10:5x5.5:-25:-;35x12.50R18:18x10:5x5.5:-19:-;295\/70R18:18x10:5x5.5:-19:-;35x12.50R18:18x10:5x5.5:-18:-;295\/70R18:18x10:5x5.5:-18:-;35x12.50R20:20x9:5x5.5:-12:-;35x12.50R20:20x9:5x5.5:+0:-;35x11.50R20:20x9:5x5.5:+0:-;35x12.50R20:20x9:5x5.5:+1:-;35x11.50R20:20x9:5x5.5:+1:-;35x12.50R20:20x10:5x5.5:-25:Minor Trimming;35x12.50R20:20x10:5x5.5:-19:Minor Trimming;35x12.50R20:20x10:5x5.5:-18:Minor Trimming;35x12.50R22:22x10:5x5.5:-25:Minor Trimming;35x12.50R22:22x10:5x5.5:-19:Minor Trimming;35x12.50R22:22x10:5x5.5:-18:Minor Trimming;35x12.50R22:22x12:5x5.5:-44:Trimming Required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 500-77-79.20\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003ePlease confirm your exact vehicle, year and trim before ordering.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Rough Country","offers":[{"title":"Default Title","offer_id":50046208147527,"sku":"RC-500-77-79.20","price":719.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/5953\/2615\/files\/1973_-_1979_4wd_f-150_4in_n3_suspension_-_500-70-76_20_500-77-79_20_530_535_20-2_1.jpg?v=1794199798","url":"https:\/\/easternperformance.com\/products\/rough-country-4-inch-lift-kit-rear-springs-ford-f-100-f-150-4wd-1977-1979","provider":"Eastern Performance Cycles","version":"1.0","type":"link"}
