Bilstein B6 4600 Series Front Shock Absorber – 2015–2020 Ford F-150 | 46mm Monotube | OEM Height | 24-337137

The Bilstein B6 4600 is the definitive OEM-height performance shock absorber upgrade for the 2015–2020 Ford F-150 — delivering a significant improvement in ride quality, handling precision, and damping consistency over the factory shock absorbers without changing ride height or requiring any suspension modifications. Engineered as a direct bolt-on replacement for the front factory shocks on the 13th generation aluminum-body F-150, the B6 4600 brings Bilstein’s legendary monotube damping technology to a truck platform that deserves better than what the OEM shocks provide. Sold individually — order two for a complete front axle replacement.

Why the B6 4600 Over the Factory F-150 Shocks?

The factory shock absorbers on the 2015–2020 F-150 are engineered to a cost and comfort target — not a performance target. They use a twin-tube design that is prone to aeration (oil and gas mixing) under repeated or aggressive use, causing fade and inconsistent damping. On a truck that may be used for towing, hauling, off-road driving, or simply driven hard on rough roads, the factory shocks can feel vague, wallowy, and unpredictable — particularly when the truck is loaded or when road conditions change rapidly. The Bilstein B6 4600 addresses all of these shortcomings with a 46mm monotube design that delivers consistent, fade-free damping under all conditions.

Key Features

• 46mm Monotube Design – Fade-Free Performance: The B6 4600 uses a single-tube (monotube) construction with a 46mm bore — significantly larger than the factory twin-tube design. The monotube layout physically separates the oil and high-pressure gas charge with a floating piston, eliminating aeration and the damping fade it causes. The larger bore provides more oil volume and a larger piston surface area, improving heat dissipation and maintaining consistent damping performance under sustained use — whether towing on a long highway run or navigating rough terrain
• Velocity-Sensitive Digressive Piston: The B6 4600’s unique digressive piston design reacts to changing road conditions in real time — providing firm, controlled damping during aggressive manoeuvres and load changes, while softening appropriately for small, high-frequency road inputs like pavement imperfections and gravel. The result is a shock that feels both more controlled and more comfortable than the factory unit simultaneously — not a compromise between the two
• Application-Specific Tuning: Every B6 4600 is tuned by Bilstein’s engineers for the specific vehicle application — not a generic valving spec applied across multiple platforms. The 24-337137 is tuned specifically for the 2015–2020 F-150’s weight, suspension geometry, and spring rates, ensuring the damping characteristics are optimised for this truck rather than adapted from a similar application
• OEM Height – No Lift Required: The B6 4600 is designed for stock ride height applications — it is a direct performance upgrade, not a lift kit component. Installs in the factory shock location using the factory mounting hardware with no modifications to the suspension, body, or drivetrain
• Direct Bolt-On Fitment: Engineered as a direct replacement for the factory front shock absorbers on the 2015–2020 Ford F-150 — uses OEM mounting points and hardware. No modifications required
• Bilstein Quality – German Engineering: Bilstein has been manufacturing monotube shock absorbers since 1954 and is the OEM shock supplier for numerous performance and luxury vehicle manufacturers worldwide. The B6 4600 is built to the same quality standards as Bilstein’s OEM supply products

Fitment

• Ford F-150 13th Generation P552 — 2WD (2015–2020)
• Ford F-150 13th Generation P552 — 4WD / 4x4 (2015–2020)
• All cab configurations (Regular, SuperCab, SuperCrew) — verify your specific configuration before ordering
• Compatible with all engine variants (2.7L EcoBoost, 3.5L EcoBoost, 5.0L Coyote V8, 3.3L V6) — verify fitment for your specific build

Note: Fitment may vary by cab configuration, drivetrain (2WD vs 4WD), and suspension package (e.g. FX4 Off-Road package). Verify your specific configuration is compatible using the part number 24-337137 before ordering. Not compatible with lifted F-150 applications — the B6 4600 is an OEM-height shock.
