Overview

The RoadActive Suspension 3611-YHD is a heavy-duty leaf spring enhancement kit designed to stabilize Ford F-150 4WD models from 2009-2026, excluding the Raptor. It strengthens the rear leaf springs, improves towing and hauling performance, and reduces rear bounce, axle wrap, and squatting.

The kit is constructed from durable steel with corrosion-resistant coatings and requires no maintenance or readjustments after installation. It aims to provide improved stability and handling without compromising unloaded ride quality.
Show original supplier description
It effectively reduces rear squat, excessive bounce, sway, and body roll without the complexity of airbags or a harsh unloaded ride. This fully mechanical 3-in-1 system integrates the functions of a helper spring, sway bar, and traction bar into a single, simple bolt-on upgrade. The system helps provide up to a 50% increase in rear suspension strength, reduces rear squat by up to 2 inches, and improves towing and hauling stability. It also mitigates sway, bounce, and axle wrap, while aiming to maintain or improve unloaded ride quality. Installation is straightforward and can typically be completed in about 45-60 minutes using basic hand tools and jack stands. The RoadActive Suspension system requires zero maintenance, making it a convenient and effective solution for improving a truck's performance under load and during daily driving. The kit comes fully assembled and ready for installation, with detailed guides and videos available. This specific kit is designed for the Ford F-150 (4WD) from 2021 to 2026. It is important to verify fitment manually as no automatic fitment data is available for this specific SKU on all platforms. RoadActive Suspension also offers a 30-day money-back guarantee, though customers are responsible for return shipping costs. The product is made in the USA and backed by a 5-year warranty.
