ISX In-Frame Overhaul Kit | 150MM APR Liners + Thermostat & Piston Cooling Nozzles | OEM: 4352294
This complete Cummins ISX in-frame kit is built for durability, performance, and compatibility. It includes 150MM APR (Anti-Polish Ring) liners, a full gasket set, thermostat, injector seals, and piston cooling nozzles. Whether your ISX uses fracture split rods or saw cut rods, this kit has you covered — it includes both bearing styles to support either connecting rod type.
⚙️ Fits Both Rod Styles:
This kit is preconfigured for fracture split connecting rods (most common in later ISX engines), but it also includes components to support saw cut rods, giving you peace of mind no matter your configuration. Just verify your rod style before installation and use the correct bearing set included.

💡 What is an APR Liner?
APR = Anti-Polish Ring, a hardened band at the top of the liner that reduces carbon polishing and protects the liner wall. This helps:
✅ Extend liner life
✅ Improve oil control
✅ Reduce cylinder wear
✅ Maintain power over time
