In this review of the Gabriel G64000 Ultra Truck rear shock absorber, the bottom line is simple: this is a sensible OE-style replacement for owners of heavy duty Chevrolet Suburban 3500 HD and Hummer H2 models who want firmer, controlled rear suspension without complex setup. The reviewer found the unit delivers noticeably improved ride control and confident handling on daily driven trucks, with straightforward bolt-on installation and durable twin tube construction. It is best suited where reliability and predictable damping are priorities rather than a plush, soft ride.

Who It's For

This Gabriel Ultra Truck shock is aimed at owners of the 16-19 Chevrolet Suburban 3500 HD and 03-09 Hummer H2 who need a robust OE-style replacement that restores steering stability and rear axle control.
