Why Rebuild Instead of Replace? Rebuilt Jeep J-Engine for sale.

🔧 Classic Engines, Reborn

Every Jeep J-Series engine we sell is meticulously remanufactured to OEM specs—or better. Our rebuild process includes:

• Full disassembly and inspection

• Cylinder head and block machining

• Installation of new pistons, rings, gaskets, bearings, oil pump, timing components

• Final assembly and testing (compression and oil pressure checks)

These rebuilt engines deliver like-new performance while retaining the character and durability that made Jeep trucks legendary.

💰 Big Savings Over New

Finding new engines for older J-Series models is tough—and expensive. A rebuilt engine offers excellent reliability at a lower cost, especially for rare or discontinued models.

Popular Jeep J-Series Engine Options

We carry rebuilt engines for many 1963–1988 Jeep J-Series trucks, including:

• AMC 258 I6 (4.2L) – Smooth-running inline-six, popular for reliability

• AMC 304 V8 (5.0L) – Found in earlier J10s and Wagoneer models

• AMC 360 V8 (5.9L) – The most common J10/J20 engine—ideal for towing/off-roading

• AMC 401 V8 (6.6L) – Rare and powerful; available upon request

Not sure which engine you have? Just send us your VIN, model year, or photos, and we’ll match you with the correct rebuilt engine.
