Momentum Worx CAT C13 ACERT Single Turbo Conversion Kit

Momentum Worx: The Premier Supplier of Single Turbo Kits for Caterpillar Engines

The CAT C13 ACERT leaves the factory with a highly efficient—but extremely complex—compound Garrett turbocharger system. Two turbos, multiple bellows, added air-to-water cores, extra plumbing, and layers of hardware packed onto the right side of the engine. Yes, the system works, but it’s a nightmare to service. Even simple repairs become all-day jobs.

The Momentum Worx Single Turbo Conversion Kit simplifies everything. You remove the clutter, eliminate the fragile components, and replace the compounds with one properly sized turbocharger and a proven, durable manifold. The result? A cleaner engine bay, easier service access, fewer failure points, and a more straightforward turbo system that any shop can troubleshoot.

Momentum Worx is the premier supplier in this market for a reason: we use proven components, premium materials, American manufacturing, and we do not sell junk—ever.

Why SHOULD You Consider Switching to a Single Turbo?

You are an ideal candidate for a single turbo conversion if:

• One or both of your factory turbos is failing or worn
• Your factory manifold is cracked
• Your bellows continue to split or leak
• You want a simpler, easier-to-service turbo configuration
• You want to eliminate system complexity without sacrificing reliability

A single turbo offers simpler maintenance, easier access, fewer parts to fail, and dramatically reduced labor time for future repairs.

The tradeoff? Your powerband becomes slightly more narrow. Many operators never notice it, but it is worth understanding before converting.

Why SHOULDN’T You Switch to a Single Turbo?

If your compound system is in excellent condition—no turbo issues, no manifold cracking, no bellows failures—there is no practical reason to remove functioning compounds purely to “single” the truck.

Momentum Worx sells single kits, not false promises. If your system is healthy, keep running it.
