4PCS Rear Leaf Spring Insulator Bushing Inserts for 2015-2020 Ford F-150, Heavy Duty Spring Pad Silencer Kit, Replaces FL3Z-5586-B FL3Z5586B FL34-5586-AA

Restore Your F-150’s Quiet Ride & Suspension Integrity If your 2015-2020 Ford F-150 sounds like a squeaky old wagon every time you hit a bump or turn a corner, the culprit is likely your worn-out leaf spring insulators. These small but crucial pads prevent the metal spring leaves from rubbing together. Once they wear through, the resulting friction causes noise and accelerated wear. Why Our Inserts are the Professional Choice: Heavy-Duty Performance: F-150s are workhorses. We designed these bushings to handle the stress of heavy payloads and towing without flattening or cracking. Weather Resistant: Engineered to withstand extreme temperatures, mud, road salt, and debris without degrading. The Complete Solution: Our 4-piece kit ensures you have everything needed to replace all high-friction points on your rear axle. Compatibility: Vehicle: 2015, 2016, 2017, 2018, 2019, 2020 Ford F-150 (All Trims) Interchange Part Numbers: FL3Z-5586-B, FL3Z5586B, FL34-5586-AA, FL34-5586-AB, FL34-5586-AC. Pro Tip: For the easiest installation, use a large flat-head screwdriver or pry bar to separate the spring leaves, and remember to wear gloves to protect your hands!
