When many people think of FASS Motorsports, they picture lifted trucks, big tires, aggressive wheels, and high-horsepower diesel builds.
And while we absolutely love building those trucks…
That’s not all we do.
Here at FASS Motorsports in Washington, Missouri, we also service a huge number of work trucks and daily drivers for customers throughout Franklin County and the greater St. Louis area.
Not every truck needs to be loud, lifted, or show-oriented. Many trucks just need to be reliable, comfortable, efficient, and ready to work.
Most Trucks We Work On Are Work Trucks & Daily Drivers
The reality is simple:
Many of our customers use their trucks to make a living or get to work every day.
These owners care about:
- Reliability
- Ride quality
- Load handling
- Visibility
- Fuel system protection
That’s where we shine.
Airbags & Load Support
One of the most common upgrades we install on work trucks is airbag helper springs.
Airbags help:
- Level the truck under load
- Reduce rear-end sag
- Improve stability while towing
- Protect suspension components
If you tow or haul regularly, airbags are one of the best investments you can make.
Shock Replacement & Ride Quality Improvements
Worn-out shocks make a truck ride poorly, handle poorly, and feel unsafe.
We replace shocks on stock-height trucks, leveled trucks, and work trucks every week.
New shocks can:
- Improve ride comfort
- Reduce body roll
- Improve control while towing
- Restore factory-like handling
You don’t need a lift kit to benefit from better shocks.
Lighting Upgrades for Real-World Use
Work often doesn’t stop when the sun goes down.
We install lighting upgrades such as:
- LED headlights and fog lights
- Reverse lights
- Bed lighting
- Work lights
Better lighting improves safety and makes nighttime work easier.
FASS Diesel Fuel Systems
Clean fuel is critical for modern diesel engines.
We sell and install a large number of FASS Diesel Fuel Systems for customers who want:
- Better filtration
- Consistent fuel pressure
- Injector and pump protection
- Longer fuel system life
Many daily-driven and work trucks run FASS systems purely for reliability — not horsepower.
FASS EGR Filter Kits
Another popular reliability-focused upgrade is the FASS EGR Filter Kit.
These kits help reduce soot and contamination that can enter the intake through the EGR system, keeping components cleaner over time.
It’s a simple addition that supports long-term engine health.
Maintenance-Friendly Upgrades
We sell and install many products that simply make trucks easier and cheaper to own:
- Steering and suspension components
- Cooling system upgrades
- Intake systems
- Exhaust components
Not everything has to be extreme to be worthwhile.
