Product Description

Piston Ring Kit for ISB/QSB 6.7L 24-Valve Engines (4955160 4934860)

 

Piston 4955160 is a steel crown aluminum skirt piston for turbo common rail diesel engines, widely used for overhaul of heavy trucks and mining machinery. It has five core features:

  1. Combustion bowl with radial diversion ribs. Built-in ribs break concentrated fuel spray and spread mist evenly for common rail injection. It eliminates overheated hot spots and reduces thermal cracking on the piston crown.
  2. Independent inner annular cooling gallery. Closed oil passage circulates lubricant under the bowl to carry away combustion heat. It delivers superior heat dissipation and suits long continuous full-load operation.
  3. Protective raised land above top ring groove. The shoulder blocks direct hot gas erosion on the groove base. It slows wear, preserves ring clearance, and controls blow-by and oil consumption over service time.
  4. Angular micro oil pockets on skirt. Slanted recesses trap lubricant during reciprocating movement and build a stable oil film on liner wall. It improves lubrication at cold start and load reversal to prevent cylinder scuffing.
  5. Multi-dimensional precision sorting inspection. Combustion volume, pin bore concentricity and skirt profile are verified. Pistons are sorted by tight weight tolerance to keep balanced engine rotation and reduce vibration and abnormal noise.

This interchangeable aftermarket piston is available individually or as a full kit with piston pin, circlips and rings. When assembled with cylinder liner kits, it offers reliable durability under long-haul and variable mining loads.
