KONI 8041-1409Sport Sport Rear Shock Yellow for 2013-2018 Ford Focus ST 2.0L FWD

Vehicle Fitment

• 2013-2018 Ford Focus ST Hatchback (C346; L4 2.0L EcoBoost, FWD)

Fitment Notes

• Rear shock absorber - position is Rear Left and Rear Right. Sold individually (per shock); two units are required for a complete rear axle replacement set.
• Fits the Ford Focus ST Hatchback (Mk3, C346 platform) only - specifically engineered for the ST's unique suspension tune and rear shock mounting geometry. Does not fit any non-ST Focus variant including the standard Focus, Focus SE, Focus SEL, Focus Titanium, or Focus Electric.
• Does not fit the Ford Focus RS - the RS uses a different rear suspension architecture (rear twist-beam vs. the ST's independent rear suspension is not correct; the ST uses a rear twist-beam, but the RS uses a fully independent rear multi-link). Verify your specific model before ordering.
• The Focus ST was sold in North America exclusively as a 5-door hatchback from the 2013 through 2018 model years. Production of the Focus ST ended for the North American market after 2018.
• Compatible with OEM spring rates and performance lowering springs up to 35 mm (approximately 1.4 in) of drop.
• Sold per shock - two rear units required for a complete rear axle installation. The companion front shock for the Focus ST is a separate KONI Sport part number (8741-series strut insert).

Features

• KONI Sport 8041 Series externally adjustable rebound damping - the adjustment knob at the top of the damper allows rebound to be tuned from full soft to full firm without removing the shock from the vehicle, by simply turning the knob clockwise to soften or counterclockwise to firm the ride.
• Approximately 100% rebound adjustment range - up to three times the range of competing adjustable shock designs - allowing the damping to be set for comfortable daily street use or firmed up for spirited road driving, autocross, and track day sessions without hardware changes.
• Twin-tube, low-pressure gas-charged damper construction specifically engineered for the Focus ST's rear suspension geometry, delivering improved road holding, reduced body roll, and more composed rear axle behavior over OEM or worn stock shocks.
• Yellow-painted shock body - KONI Sport's iconic finish and a benchmark rear shock upgrade for the Focus ST platform within the Ford performance community, frequently recommended alongside lowering springs and full coilover kit setups.
• Significantly reduces rear body roll, rear squat under hard acceleration, and pitch under braking - refining the Focus ST's already sporty handling character and improving confidence and consistency during performance driving scenarios.
• Fully compatible with performance lowering springs up to 35 mm of drop from brands including Eibach, H&R, and Mountune designed for the Focus ST, allowing a correctly damped lowered setup without a different shock specification.
• Re-buildable and re-valvable - the shock can be serviced and returned to factory-equivalent performance after extended use, or re-valved for custom damping specifications for dedicated track or rally use.
• Backed by KONI North America's Limited Lifetime Warranty for street use in the United States and Canada.

Product Description

The KONI 8041-1409Sport is a yellow-painted, externally adjustable rear shock absorber from KONI's Sport 8041 Series, engineered exclusively for the 2013-2018 Ford Focus ST Hatchback (Mk3, C346 platform) - the turbocharged 2.0L EcoBoost, front-wheel-drive hot hatch sold in the North American market through 2018. This is a Focus ST-specific part: it is engineered to the ST's unique rear suspension geometry and valving requirements, and does not fit any non-ST Focus model. As a Sport Series 8041 damper, the 8041-1409Sport delivers improved rear body roll resistance, reduced squat under hard acceleration, and more composed rear axle behavior over OEM or worn stock shocks, with the external rebound adjustment knob providing quick, on-car tuning without removing the shock from the vehicle.

The external rebound adjustment spans approximately 100% of the damping range - from a soft, daily-driver setting to a firm, performance-tuned configuration - making it practical to adapt the Focus ST's rear damping to a wide variety of spring rates, road conditions, and driving applications. Turning the knob clockwise softens the rebound; counterclockwise firms it. The shock is fully compatible with performance lowering springs up to 35 mm of drop from manufacturers including Eibach, H&R, and Mountune, and the twin-tube, low-pressure gas-charged construction provides consistent, predictable damping across the focus ST's full dynamic range - from spirited street use to autocross and track day sessions.

The Focus ST was produced for the North American market from the 2013 through 2018 model years in a single 5-door hatchback body style with the 2.0L EcoBoost engine and FWD drivetrain - there are no sedan, AWD, or alternative engine variants to consider for this application. This shock is sold individually - two units are required for a complete rear axle installation. The companion front shock absorber for the Focus ST uses a separate KONI Sport 8741-series strut insert. The damper is re-buildable and re-valvable, extending its service life and enabling custom valving for dedicated performance builds. Backed by KONI North America's Limited Lifetime Warranty for street use in the United States and Canada.
