Product Details

The Excel-G line is KYB’s Original Equipment for the Aftermarket offering, built to restore the vehicle’s original suspension behavior rather than change it. Part number 345601 uses the same type of OE-quality components found on KYB global OEM products and is tuned to manage tire contact, steering response, and body movement. This part cross-references Monroe Shocks & Struts 66605 and Gabriel 83613 for the same application.

Use KYB 345601 when you need a suspension shock absorber that supports factory-style ride control on compatible Isuzu truck and commercial vehicle applications. The design also helps electronic safety systems operate as the vehicle manufacturer intended by keeping suspension, brakes, and tires working together correctly.

What It Helps Address

• Excessive bounce after bumps
• Loose or delayed steering response
• Reduced stability during lane changes
• Uneven tire contact caused by worn damping
• Oil or gas leakage from an aging shock absorber

Installation Notes

Verify compressed length, extended length, stroke length, and mount types before installation. This KYB shock absorber uses an S1/2X13 lower mount and an S1(1/2) upper mount, so confirm the mounting points on the vehicle before ordering. For best results, inspect related suspension components and align the vehicle after replacement if required by the application.

Compatible With select Isuzu truck and commercial vehicle applications. Fits should be confirmed by year, model, and position before purchase.
