Helpful Notes
- Machine work is required for .020” overbores. Verify piston-to-wall clearance and ring end gaps per spec.
- Choose valve reliefs (.100") if running a high-lift cam or tight piston-to-valve clearance.
FAQ
Are these truly “drop-in”?The kit includes rings, pins, and clips; however, a .020” overbore and precise measurements are required to set proper clearances.
Cast vs. forged — which should I pick?Cast pistons like PDM-360.020 are ideal for tuned street/haul builds. For higher cylinder pressure and competition, consider forged (PDM-362 series).
Do these come with coatings?Yes. They include a thermal barrier crown coating and a skirt coating to reduce friction and manage heat.
What ring sets match this bore?Use (.020) ring sets that match your year family (e.g., MAHLE 41909.02 for LB7, MAHLE 42160.02 for LML). See the links above.
