Product Details

KYB’s Truck-Plus Leveling Assembly line is engineered for truck and SUV front suspension service where the strut assembly affects more than ride comfort. On these Chevrolet Silverado 1500, GMC Sierra 1500, Tahoe, Yukon, Suburban 1500, Yukon XL 1500, and Avalanche applications, the assembly supports front ride height while also serving as part of the steering and stability system. KYB uses application-specific part numbers rather than a one-size-fits-all design, which helps match the original suspension layout for the exact vehicle configuration listed.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Can Address

• Front-end sag or reduced ride height
• Worn strut assembly performance on the listed trucks and SUVs
• Loose or inconsistent steering feel from a tired front suspension unit
• Reduced stability during braking, cornering, or load transfer
• Suspension noise or poor damping from an aging assembly

Installation Notes

Verify exact vehicle fitment before installation, including model year and suspension package exclusions. This assembly is for front position use only and does not apply to vehicles with electronic suspension, Premium Smooth Ride Suspension, ZW7 Premium Smooth Ride Suspension, or the Police Package where noted in the fitment data. Because the strut assembly affects ride height and steering geometry, a professional alignment is recommended after installation.

Quality Assurance

KYB designs the Truck-Plus Leveling Assembly as a vehicle-specific replacement solution for the listed applications, with corner-specific engineering intended to restore the suspension function expected for each platform. Part number SRX4079 is built for the front suspension positions shown in the fitment data.
