FAQ
Are these file-fit?
No—the rings are pre-lapped, installer-friendly. Always verify end gaps to Mahle specs.
Will .010" work for my rebuild?
Use .010" only after confirming the block has been bored/honed to .010" oversize. Measure each cylinder.
Do these fit E-Series vans?
Often yes on 6.0L VT365 vans—always verify VIN, bore size, and oversize before purchase.
Break-in tips?
Use the correct hone finish, verify end gap/orientation, and vary load for the first 500 miles with fresh oil.
