KYB Shocks & Struts Excel-G Rear FORD Focus ST 2013-16

Bring Back Factory Composure to a Focus ST That’s Lost Its Edge

Worn rear shocks on a hard driven Focus ST let the rear end bounce and wallow through corners instead of staying settled, robbing the car of the sharp handling it had when new. The KYB 3440047 Excel-G rear shock is built on the same OE assembly lines KYB uses for original equipment, using a nitrogen gas charged twin tube design with a triple plated chrome piston rod for smooth, consistent damping. It’s calibrated to match the Focus ST’s original engineering rather than to soften or stiffen the ride, so you get factory feel back without changing how the car was designed to drive.

Key Features

• Nitrogen gas charged twin tube design for consistent damping control

• Calibrated to restore the Focus ST’s original equipment ride and handling
• Built on the same OE assembly lines KYB uses for factory production

FAQ

What is the KYB 3440047 shock?

It’s a rear Excel-G shock absorber built by KYB as a direct fit replacement for the 2013 through 2016 Ford Focus ST, using the same nitrogen gas charged twin tube design and OE quality components found in KYB’s original equipment production.

Is this shock sold as a single unit or a pair?

The 3440047 is sold individually, so two are needed to replace both rear shocks on the vehicle.

Should I replace both rear shocks at the same time?

Replacing both rear shocks together is generally recommended so damping feels even side to side, especially if the shocks are original and have significant mileage.

Will this shock work with a lowering spring or coilover setup?

This shock is calibrated to match the factory Focus ST suspension geometry and stroke length, so it’s intended for use with factory or factory-height replacement springs rather than aggressively lowered setups.

Does installing this shock require an alignment afterward?

A basic alignment check is a good practice after any rear suspension work, though a direct shock swap at stock ride height typically has minimal effect on alignment angles.

What tools are needed to install this shock?

Basic hand tools, a way to safely support the vehicle, and typically a spring compressor if the strut assembly needs to be disassembled are sufficient for most installations.

Does this shock come with a warning label?

Yes, this product includes a California Proposition 65 warning regarding chemicals known to cause cancer or reproductive harm, which is standard for many automotive components sold in the United States.

How long should a KYB Excel-G shock last?

KYB Excel-G shocks are commonly reported to perform well well past 100,000 miles under normal driving conditions, consistent with their OE-grade construction.
