MonoMax Product Line Details

KYB MonoMax shocks are part of KYB’s heavy-duty truck-focused line. They are built for vehicles that do real work, including towing, hauling, and off-road driving, where consistent damping and durability matter. The KYB MonoMax 565023 uses a work-ready construction intended to maintain control under load while helping reduce fade during repeated suspension movement.

Detailed Description

Compatible with 1992-2002 Isuzu Trooper rear, 1999-2001 Isuzu VehiCROSS rear, and 1996-1999 Acura SLX rear, this KYB shock absorber is a direct-fit suspension upgrade for applications that need firmer rear-end control. The large-bore monotube design helps the shock respond consistently to changing road conditions, while the zinc-coated piston ring and off-road dust boot support durability in harsh environments. Part number 565023 is a practical choice for owners of the Isuzu Trooper, Isuzu VehiCROSS, and Acura SLX who want a rear shock built for load-carrying and demanding driving conditions.

What It Helps Address

• Excessive rear suspension bounce over uneven pavement
• Reduced control when towing or hauling heavy loads
• Body movement in higher center-of-gravity vehicles
• Shock fade during repeated off-road or rough-road use
• Wear from dirt, debris, and harsh operating conditions

Installation Notes and Tips

Verify rear fitment by year, make, and model before installation. This shock uses lower mount type E1L/E(19) and upper mount type E2(14X38), so confirm mount style and dimensions against the vehicle before service. Inspect related suspension components, including bushings and mounting points, and replace worn parts as needed to restore proper ride control. Part number 565023 should be matched to the rear position only.

Quality Assurance

KYB builds the MonoMax line for heavy-duty suspension use, with a monotube construction and sealed piston ring designed for demanding truck and SUV applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
