Nothing like riding down the road and the cab filling up with smoke to get your attention. I know why Freightliner named these trucks the Cascadia, after the first repair it's nothing but cascading issues. #freightliner #freightlinercascadia #breakdown #roadservice #trucking #truckinglife #trucker #truckerslife #driverslife #cdllife #lifeontheroad (at Wind Gap, Pennsylvania) https://www.instagram.com/p/B-sL8v3JY1Y/?igshid=129ei4j4nj35c

Welcome to PA. 20 MPH on a 9% grade with a truck that has Jake Brakes that shut off at 30 MPH. I really do not like this Cascadia - Cummins combo that Ryder spec'd out. If you don't know how to navigate a down grade without engine brakes you should learn before you're in a situation like this. #pennsylvania #pa #hill #downgrade #downhill #2lane #enginebrake #jakebrake #trucking #truckerslife #driverslife #drivinglife #truckinglifestyle #cdl #cdllife #18wheels #lifeontheroad #officeview #freightliner #freightlinercascadia #cummins #ryder #rydernationallease

Why Buy a Used 2021 Freightliner Cascadia Engine?
Buying a Used 2021 Freightliner Cascadia Engine is a strategic decision for many truck owners.
1. Significant Cost Savings
A brand-new diesel engine can cost upwards of $25,000–$40,000. In contrast, a used engine typically ranges between $8,000 and $18,000, depending on condition and mileage.

3. Proven Real-World Performance
Used engines have already been tested on the road. When sourced from a reliable supplier, they offer dependable performance for years.
Risks of Buying a Used Engine
While the benefits are strong, there are real risks you need to understand.
1. Unknown History
Without proper documentation, you may not know:
Maintenance records
Driving conditions
Previous failures
2. Hidden Internal Damage
Engines may look good externally but have internal issues such as:
Worn pistons

3. Mileage Misrepresentation
Some sellers may provide inaccurate mileage information.
4. Weak Warranty Protection
Not all suppliers offer strong warranties, leaving you exposed to repair costs.
