Race-Proven Off-Road Damping for Fabricated and Custom Suspension Builds
The FOX 2.0 Performance Elite Emulsion Coilover Shock combines FOX's race-proven damping technology with a coilover spring perch in one bolt-on assembly. This 7/8 in. shaft, 10 in. travel emulsion shock is built for off-road fabrication, trophy truck, buggy, and long-travel suspension applications where the builder selects and mounts the shock to a custom or aftermarket suspension arm.
Key Features
- 2.0 in. body diameter emulsion shock with 10 in. of travel
- 7/8 in. hard chrome-plated 4130 chromoly steel shaft for increased side-load strength
- High-flow 2.0 piston tuned for off-road damping performance
- Owner serviceable and rebuildable
- Coilover spring perch accepts aftermarket coil springs (sold separately)
- Zinc-plated seamless alloy body for corrosion resistance
Fitment
This is a universal off-road racing shock sold by dimension and configuration (2.0 in. body, 10 in. travel, 7/8 in. shaft, emulsion type), not by vehicle year, make, or model. It is intended for fabricated, custom, or aftermarket suspension systems on off-road vehicles, buggies, and trophy trucks where the builder determines correct fitment based on shock length and mounting geometry, not a specific factory vehicle application.

FAQ
Does this shock include a coil spring?No, this is the shock body only with a coilover spring perch. Springs are sold separately and must be matched to the application.
What vehicles does this shock fit?This is a universal off-road shock sold by dimension, not vehicle-specific. It fits any application where a 2.0 in. body, 10 in. travel, 7/8 in. shaft emulsion coilover is the correct specification.
What does emulsion mean for this shock?Emulsion means the nitrogen gas and shock oil are mixed together in the same chamber rather than separated by a floating piston or remote reservoir.
Can this shock be rebuilt or serviced?Yes, it is owner serviceable and rebuildable.
What is the shaft material?The shaft is hard chrome-plated 4130 chromoly steel for increased strength and resistance to side loads from coil springs.
How is this shock mounted?It mounts using eyelets at the top and bottom with 1/2 in. diameter bolts and a 1-1/4 in. mounting width.
Is this shock adjustable?This emulsion version does not include external compression or rebound adjusters; valving is fixed at the factory setting.
What is the difference between the 7/8 in. and 5/8 in. shaft versions?The 7/8 in. shaft offers greater strength and side-load resistance and is recommended for heavier off-road vehicles and long-travel setups, while the 5/8 in. shaft is intended for lighter buggies and sand rails.
Installation Instructions
- Determine correct shock length and travel for the intended suspension geometry before purchase, since fitment is dimension-based rather than vehicle-specific.
- Mount the shock body-side up per FOX's emulsion shock orientation requirement.
- Install upper and lower mounting eyelets to the vehicle's suspension arm and chassis mounting points using the specified 1/2 in. bolts.
- Install the coilover spring (sold separately) onto the spring perch and secure the spring retainer.
- Torque all mounting hardware to the suspension manufacturer's specification.
- Cycle the suspension through its full range of travel to confirm clearance before returning the vehicle to service.
