Why Planning Ahead Matters in Today’s Vocational Truck Market
The vocational truck market is entering another period of transition.
As manufacturers roll out new engine platforms to meet evolving emissions requirements, fleet owners and managers are facing important decisions about future truck purchases. Along with new technology comes the potential for anticipated increases in acquisition costs, changing production schedules, and reduced availability of today’s proven engine platforms.
At Klein Products, we saw these changes coming.
Instead of waiting for the market to change, we made the decision to plan ahead.
“At Klein, we’ve always believed our responsibility extends beyond building great equipment. It’s about helping our customers make sound long-term decisions. When we saw the market changing, we made the decision to invest early so our customers would have more options, greater certainty, and more confidence in their fleet planning.”
Barry McManus, President, Klein Products
What’s Changing?
The proven PACCAR PX-9 engine is being phased out as manufacturers transition to new engine technology.
As that transition occurs, trucks equipped with the PACCAR PX-9 are expected to become more difficult to obtain. Future orders may also be subject to anticipated increases in acquisition costs, including compliance-related surcharges associated with the changing emissions landscape.
For organizations planning truck replacements over the next several years, these changes could affect both equipment availability and capital budgets.

Why Klein Planned Ahead
Rather than waiting for those changes to affect our customers, Klein secured production allocation for new 2027 Peterbilt 548 chassis equipped with the proven PACCAR PX-9 engine.
These are not leftover trucks.
They are new 2027 model year chassis that allow our customers to continue purchasing a proven platform while helping reduce exposure to anticipated increases in acquisition costs, compliance-related surcharges, and future availability challenges.
We didn’t secure these trucks because the market changed. We secured them because we knew it would.
That’s what planning ahead looks like.
What This Means for Your Fleet
If replacing or expanding your fleet is already part of your long-term plan, securing equipment before the market fully transitions may help you:
- Continue purchasing the proven PACCAR PX-9 platform.
- Reduce exposure to anticipated increases in acquisition costs.
- Avoid potential compliance-related surcharges.
- Improve capital budget certainty.
- Simplify the purchasing process.
- Keep fleet replacement plans on schedule.
At Klein Products, we’ve spent nearly seventy years helping customers solve problems before they happen. This investment reflects that same philosophy.

The market is changing. Our commitment to our customers hasn’t.
