Detailed Description

Arnott SK-3354 is engineered as a front coil-over shock assembly for 2015-2020 Cadillac Escalade, 2015-2020 Cadillac Escalade ESV, 2015-2020 Chevrolet Tahoe, 2015-2020 GMC Yukon, and 2015-2020 GMC Yukon XL equipped with Z95 Magneride suspension.

The Arnott NEW product line focuses on replacement suspension components built for direct fitment and application-specific performance. SK-3354 follows that approach with custom valving and a passive setup that matches the original front suspension layout on these GM SUVs. If you are searching for a front strut assembly for 2015-2020 Cadillac Escalade or 2015-2020 GMC Yukon XL with Magneride, SK-3354 provides a complete service solution for the front corner.

Common Problems This Part Can Address

• Front-end bounce or reduced damping control
• Uneven ride height caused by worn coil-over components
• Noisy suspension operation from worn mounts or isolators
• Loss of steering stability over bumps and rough pavement
• Ride quality decline from aging Magneride front struts

Installation Notes and Tips

Install SK-3354 at the front left or front right position as specified for the vehicle. For best results, replace the front suspension strut and coil spring assembly in pairs on the same axle, especially on Magneride-equipped Cadillac Escalade, Chevrolet Tahoe, GMC Yukon, and GMC Yukon XL applications. Verify Z95 Magneride fitment before ordering and confirm all mounting points, including the cross-pin lower mount and bolt-style upper mount, match the vehicle.

Because this assembly is pre-assembled, it reduces the need to transfer spring and mount components during service. Always follow factory service procedures and perform a wheel alignment after installation.

Arnott manufactures this SK-3354 replacement as a new suspension assembly with application-specific construction for GM SUV front suspension service. The part is built with steel housing, gas-charged damping, and included wear components such as the boot, dust shield, and isolators to support consistent installation and operation.
