D&J Precision machine engine limited warranty

Engine Warranty Coverage

Our engine limited warranty covers defects in workmanship under normal use for a period of 2 years or 100,000 miles, whichever comes first, from the date of purchase. The Street Performance Series Engines, Performance Series Engines, Predator Engines, and Enforcer 6.7 Cummins Engines have a 90-day warranty coverage period.

Registration

Register your engine within 30 days of purchase.  Failure to do so will void your warranty.
