Gabriel Fleetline Heavy Duty Rear Shock Absorber for Prevost - Durable

In this review the Gabriel Fleetline 85713 rear shock absorber is presented as a heavy duty replacement for Class 8 buses and motor coaches, aimed at fleet mechanics and owners needing a direct-fit, durable unit. The bottom line: it is a purpose-built OEM replacement that improves ride quality and handles heavy service loads, with the single biggest reason to buy being its application-specific valving and robust construction designed for long-duty bus use.

Key Features

• Application fitment: Direct replacement fit for Prevost, Carpenter, Eagle and Nova Bus models reduces installation time and ensures proper alignment for Class 8 bus suspensions.
• Durable construction: 360-degree arc-welded end mounts and chromed piston rods resist corrosion and wear in demanding transit use.
• Valving tuned for heavy loads: Application specific valving compensates for worn suspension and delivers consistent damping under commercial payloads.
• Installation friendly: Upper and lower EB3 mount codes match factory mounting so mechanics can swap units without modification.
• Service lengths: Extended length 24.51 in and collapsed length 15.48 in with 9.04 in stroke provide the travel needed for heavy coach suspensions.

Who It's For

The Gabriel Fleetline 85713 is aimed at fleet maintenance teams, transit agencies and independent repair shops servicing Prevost XL II, H3 and X3 models, Nova Bus RTS with V drive, Carpenter and Eagle motor coach models. It is a good choice when a like-for-like OEM replacement is required and downtime needs to be minimized thanks to direct-fit interchange numbers.

Owners of light passenger cars or small trucks should look elsewhere; this shock is engineered for Class 8 buses and heavy-duty transit use and will not suit small vehicle suspensions or non-commercial applications.

Pros & Cons

Pros

• Built to heavy duty spec with chromed rods and arc-welded mounts for improved longevity in fleet service.

• Direct interchange with multiple OEM numbers makes sourcing and replacement straightforward.

Cons
