Mahle 4075MS-112 Performance File Fit Piston Rings
Dominate the road or track with the Mahle 4075MS-112 file fit piston rings, the ultimate upgrade for demanding engine rebuilds. Crafted with cutting-edge materials and precision engineering, these rings deliver exceptional compression retention, minimal blow-by, and enhanced power output that eclipses standard OEM rings and competitors like Wiseco or Total Seal. Featuring a robust steel top ring with advanced thermal coating for extreme heat resistance, they provide up to 20% better sealing under high boost or heavy loads, ensuring longer engine life and consistent performance beyond 100,000 miles in rigorous conditions. While budget options suffer from rapid wear and inconsistent gaps, Mahle's file fit design allows custom end-gap tuning for perfect fitment, reducing friction, improving fuel efficiency, and boosting horsepower—making them the go-to choice for enthusiasts who demand reliability and peak efficiency. Experience the difference in throttle response and reduced oil consumption that sets these rings apart as the premier solution for performance builds.
Why Mahle?
- Elite Performance Edge: Advanced steel top ring with proprietary HV385 coating outperforms moly-faced alternatives by resisting scuffing and maintaining seal integrity at elevated temperatures, leading to superior combustion efficiency and power gains over generic or uncoated rings.
- Exceptional Longevity: 1.0mm top and second rings paired with a 2.0mm oil control ring use high-tensile materials for minimal distortion, outlasting standard sets by handling higher cylinder pressures without cracking or losing tension.
- Customizable Precision: File fit +.005" oversize enables exact gap adjustment, preventing piston slap and optimizing for turbo, supercharged, or naturally aspirated setups—far superior to pre-gapped rings that compromise on fit.
- Enhanced Engine Protection: Reduces blow-by and oil dilution, preserving lubrication and cutting emissions, while supporting modern engine management systems for smoother operation and fewer failures.
- Trusted by Pros: As a leader in motorsports, Mahle rings earn top marks for value and endurance, with builders noting dramatic improvements in dyno results and track times compared to lesser brands.
Included:
- One (1) Set of Mahle Performance File Fit Piston Rings: Complete set for 8 cylinders, consisting of top rings (1.0mm, steel with HV385 thermal spray face), second rings (1.0mm, cast iron), and oil control rings (2.0mm, three-piece assembly with stainless steel rails and expander).
- Part Number: 4075MS-112 (OEM-equivalent performance replacement).
- No Additional Components: Rings only; pistons, tools, or compressors sold separately. File fitting required for optimal end gaps—consult engine specs or professional builder.
- Warranty: Backed by Mahle's limited warranty against manufacturing defects; refer to Mahle customer support for terms and activation.
Vehicle Fitment:
This Mahle 4075MS-112 ring set is designed for engines with a 4.075" bore (standard +.020" overbore applications), primarily GM Duramax diesel V8 rebuilds. Ideal for high-performance or overhauled setups; confirm bore size and compatibility with your engine builder.
