In-Frame Overhaul Kit | Cummins ISX CM2350 DOHC w/150mm APR Liners + Thermostat + Nozzles | AFA

Part Number ⚙️: 054802

If you're rebuilding a Cummins ISX CM2350 (EPA 13, Dual Overhead Cam) engine, this in-frame kit is one of the most complete and upgraded packages available. Built to match OEM 4376174, this AFA overhaul kit includes premium 150mm APR liners, a high-temp thermostat, and piston cooling nozzles—crucial upgrades for high-mileage or high-load engines.

Whether you’re doing the rebuild yourself or bringing it to a shop, this kit is a step above standard in-frame sets. Let’s break it down:


🔧 What's Included — and Why It Matters:

  • ✅ 6x 150mm APR Liners
    APR (Anti-Polishing Ring) liners prevent carbon buildup at the top of the cylinder, which can wear down your pistons and liners prematurely. These liners extend engine life, especially in engines that idle a lot or pull heavy loads.

  • ✅ Pistons with Rings, Pins, and Clips
    Replaces all six pistons with OEM-equivalent quality for consistent compression and power.

  • ✅ Main Bearings, Rod Bearings, and Thrust Washers
    All bottom-end bearings are included to ensure tight tolerances and smooth crankshaft rotation.

  • ✅ Upper & Lower Gasket Sets
    Covers the cylinder head, oil pan, and everything in between. All seals and gaskets you need for the job.

  • ✅ Thermostat (Included!)
    Helps regulate engine temperature. Most kits don’t include this, but it’s critical for cooling efficiency and longevity.

  • ✅ Piston Cooling Nozzles (Included!)
    These spray oil onto the underside of the pistons to prevent overheating under load. Perfect for haulers and long-haul engines.


📚 What Makes This Kit Different?

  • ✔️ 150mm Liners: Most standard kits come with 140mm liners. These upgraded liners are thicker, more durable, and designed for longer engine life.

  • ✔️ APR Technology: Helps eliminate liner polishing and protects your piston rings. Great for trucks that idle often.

  • ✔️ Includes Thermostat & Nozzles: Many in-frame kits don’t include these, but they’re vital for keeping your ISX running cool under pressure.

  • ✔️ Designed for DOHC Engines: This is specifically for Dual Overhead Cam ISX engines — check your valve cover or ESN to confirm.
