Arnott SK-3598 Suspension Strut and Coil Spring Assembly - Front Left

Arnott SK-3598 Front Left Strut

Arnott SK-3598 is a new passive suspension strut and coil spring assembly for the front left side of select Ford Expedition and Lincoln Navigator models. It is engineered to deliver OE-style stability, handling, control, and ride comfort without external vehicle commands.

Built for 2015-2017 Ford Expedition and 2015-2017 Lincoln Navigator applications, this assembly uses a twin-tube hydraulic design with a steel housing, gas charge, and linear spring rate. Arnott also recommends replacing these struts in pairs to maintain balanced suspension performance.

Detailed Description

Arnott NEW line SK-3598 is a direct-fit front left suspension strut and coil spring assembly for the 2015-2017 Ford Expedition and 2015-2017 Lincoln Navigator. This passive unit is built to mirror original OE performance using Arnott-engineered internal settings, giving the vehicle the stability and comfort expected from the factory suspension layout. The assembly includes a coil spring, bearing plate, spring seat, dust shield, boot, and isolators for a complete service replacement.

This part cross-references Ford FL1Z18124A for the same application.

What It Helps Address

• Front-end bounce or excessive road harshness
• Uneven ride height or sagging suspension response
• Noisy or worn strut assembly components
• Reduced steering stability and body control
• Loss of OE-like comfort on Expedition and Navigator front suspension

Installation Notes

Fits 2015-2017 Ford Expedition, front left. Fits 2015-2017 Lincoln Navigator, front left. This assembly is listed for vehicles with Adaptive Suspension (CCD). Verify the mounting style and position before installation. Because this is a complete strut and spring assembly, it is suited to replacing a worn front left unit with a matched OE-style configuration.

Quality Assurance

Arnott manufactures this SK-3598 assembly as a new suspension replacement with OE-focused internal tuning and tested settings for the listed applications. The design uses standard-grade components and a passive layout to maintain factory-like operation on the specified Ford and Lincoln models.
