Our review of the Gabriel G63604 Ultra Truck rear shock absorber finds it best suited for owners of 1989 Dodge Raider and 1989-1991 Mitsubishi Montero with the 3.0L 6-cylinder engines who want a direct OE-style replacement that improves ride control. The single biggest reason to buy is the combination of Gabriel's Infinitely Variable Damping technology and a twin tube design that delivers noticeably improved ride quality and predictable handling compared with aged original shocks, while keeping installation straightforward for DIYers.

Key Features

• Vehicle fitment: Direct fit for 89 Dodge Raider 3.0L and 89-91 Mitsubishi Montero 3.0L to simplify replacement without modification.

• Twin tube design: Precision engineered twin tube construction helps maintain consistent performance and improved handling under normal driving conditions.
• Durable construction: Built as an OE replacement with a super finished chromed rod and materials intended for long lasting use in light trucks and SUVs.
• Installation simplicity: Simple bolt-on replacement with standard upper mount EB1 and lower mount ES142 codes to match vehicle mounting points.

Who It's For

This shock is tailored for owners of the specific older SUVs listed who need a reliable OE-style rear shock replacement and want improved comfort and control compared with worn factory units. It is a sensible choice for do-it-yourselfers and independent shops because it bolts on to the listed vehicles without special tools.

Buyers who need a universal or heavy-duty off-road shock, or those who drive extensively with heavy towing loads, should look at shocks rated specifically for increased payload or adjustable damping. Also avoid this part if your vehicle is not one of the listed fitments.
