Behind Cab Hydraulic Tanks Should Not Twist With The Truck Frame
April 4, 2025For years, truck dealers and fleet service centers relied almost exclusively on OEM channels for replacement fuel tanks. But 2026 is shaping up to be a turning point. With rising OEM lead times, discontinued SKUs, and growing pressure to keep trucks on the road, more dealers are turning to OEM‑spec aftermarket tanks—and discovering that the right manufacturing partner can deliver equal or better quality, faster, and with less risk.
At MetalTanks, we’ve seen this shift firsthand. Here’s what’s driving it.
1. OEM Lead Times Are Increasing — Dealers Need Faster Solutions
Across North America, OEM supply chains are still dealing with material shortages and production bottlenecks.
Dealers report:
- Longer‑than‑normal lead times
- Unpredictable availability
- Difficulty sourcing older or discontinued tank models
When a truck is down, waiting weeks for a tank isn’t an option. Dealers are choosing aftermarket suppliers who can deliver in days, not months, without compromising on build quality.
2. OEM‑Spec Aftermarket Tanks Now Match (and Often Exceed) OEM Quality
The aftermarket used to be hit or miss. Not anymore. MetalTanks builds every tank to OEM specifications or better, using:
- Top‑grade aluminum and steel
- Precision CNC‑cut components
- Robotic and hand‑finished welds
- Pressure testing on every single tank
Dealers consistently comment on the weld quality, consistency, and fitment accuracy—especially on older models where OEMs no longer invest in tooling.
3. The Perfect Fit Guarantee™ Removes Dealer Risk
One of the biggest concerns dealers have when switching from OEM to aftermarket is simple:
“What if it doesn’t fit?”
That’s exactly why we created the Perfect Fit Guarantee™:
If a MetalTanks replacement tank doesn’t fit, we cover the return freight and replace or refund it.
Dealers appreciate that the risk is on us – not them. It’s a major reason many now keep MetalTanks as their “insurance policy” supplier for hard‑to‑source tanks.
4. Discontinued OEM Tanks Are Becoming a Bigger Problem
OEMs regularly discontinue older tank models, leaving dealers scrambling to support customers with aging fleets. MetalTanks fills that gap by:
- Recreating discontinued tanks
- Maintaining tooling for legacy models
- Offering custom fabrication when needed
This keeps older trucks on the road—and keeps dealers from losing service revenue.
5. Custom Fabrication Is Becoming a Competitive Advantage
More dealers are discovering that custom fabrication isn’t just for specialty shops.
MetalTanks builds:
- Custom fuel tanks
- Hydraulic reservoirs
- Combination tanks
- Brackets, straps, and mounting hardware
- General metal fabrication for unique applications
Dealers use this capability to solve problems OEMs can’t—or won’t—address.
6. Better Margins Without Sacrificing Quality
OEM parts pricing continues to climb. OEM‑spec aftermarket tanks give dealers:
- Better margins
- More competitive quotes
- A reliable alternative to high OEM pricing
For many, it’s simply good business.
The Bottom Line
2026 is the year dealers are rethinking their tank strategy. With OEM delays, discontinued models, and rising costs, the shift toward high‑quality aftermarket tanks is accelerating—and MetalTanks is leading that change.
Dealers want reliability. Fleets want uptime. And everyone wants a tank that fits the first time.
That’s exactly what we build.
