KUIPERAUTO Front and Rear Strut/Shock Assembly for 2009-2013 Ford F-150 4WD — Preassembled, Alloy Steel Coated Kit

Complete preassembled front and rear strut shock kit designed to directly replace the original suspension on 2009–2013 Ford F-150 4WD models.

This KUIPERAUTO assembly bundle provides a full set of front struts and rear shocks engineered for 2009–2013 Ford F-150 4WD trucks (including FX4, King Ranch, Lariat, Platinum, STX, XL, XLT with 3.5L, 3.7L, or 5.0L engines). Each unit ships preassembled with coil springs, mounts, boots, bumpers, spring seats, and isolators so you can restore ride control and handling without modifying factory components. The assemblies are built from alloy steel with an electrophoretic coating and are validated through high/low temperature cycling and durability testing for consistent damping under varied conditions.

Will this kit fit my 2009–2013 Ford F-150 4WD?

Yes — the set is made specifically to match factory fitment for 2009–2013 F-150 4WD trucks and common factory trims. It replaces the original-style struts and shocks and matches the OEM mounting points for a bolt-in installation.

• Compatible with 2009, 2010, 2011, 2012, 2013 Ford F-150 4WD
• Works with FX4, King Ranch, Lariat, Platinum, STX, XL, XLT trims
• Suitable for 3.5L, 3.7L, and 5.0L engine configurations
• Replaces OEM numbers 171141 and 4349108

How easy is installation and what comes in the box?

Installation is straightforward because the front struts and rear shocks arrive preassembled. Each assembly includes all the common components needed to match OE configuration, removing the need for separate spring compressors or custom adapters.

• Preassembled struts and shocks — coil spring, mount, boot, bumper included
• Spring seat and isolator already installed for correct ride height and noise reduction
• No modification required — designed to align with original mounting points
• Savings on labor time versus sourcing separate parts

What materials and tests were used to ensure durability?

KUIPERAUTO uses alloy steel components and an electrophoretic paint finish to improve corrosion resistance and wear life. Each assembly undergoes environmental and performance tests to verify consistent damping and structural integrity across a range of temperatures and conditions.

• Alloy steel construction for strength under heavy loads
• Electrophoretic coating to resist rust and abrasion
• High/low temperature cycling and air-blast testing for long-term reliability
• Designed to deliver balanced rebound and compression performance

What improvements should I expect after replacing my worn shocks and struts?

Fresh struts and shocks restore handling predictability, reduce body roll, and improve braking stability by maintaining tire contact with the road. The complete assemblies also help reduce cabin vibration and noise compared with fatigued or leaking components.

• Improved steering response and cornering stability
• Reduced nose dive during braking and squat under acceleration
• Smoother ride over potholes and uneven surfaces
• Decreased suspension-related noise and rattles

Who is this for: Truck owners who need a direct-fit, cost-effective replacement for worn or leaking suspension components on 2009–2013 Ford F-150 4WD models. This kit suits DIY installers and shops looking to restore ride quality without aftermarket modifications. If you want OE-style mounting, preassembled convenience, and corrosion-resistant materials for everyday driving or towing duties, this KUIPERAUTO front and rear strut shock assembly set is engineered to match those needs.
