What you're getting

What's included with this engine

You're buying a complete engine assembly — not a bare block. Here's exactly what arrives bolted to it, and the handful of accessories your mechanic moves over from your current engine during the install.

✓

Included with your engine

Already assembled — ships as one unit
  • Long block — fully assembled
  • Short block
  • Cylinder head
  • Crankshaft
  • Camshaft
  • Pistons
  • Intake manifold
  • Exhaust manifold
  • Oil pan
  • Timing cover
⇄

Not included — transfer these over

Reused from your current engine
  • Wiring harness
  • Bolt-on accessories
Why these aren't included: these parts are tied to your vehicle's exact trim and options, and the ones already on your current engine are almost always in good working order. Your mechanic transfers them across during the install — that's standard practice on an engine replacement, and it keeps your price down.
Quick definition: a short block is the block, crankshaft, camshaft and pistons. A long block adds the cylinder head and valvetrain. A complete engine — what you're buying here — is the long block with the intake manifold, exhaust manifold, oil pan and timing cover already fitted.

Frequently Asked Questions?

Q: How do I confirm my Wrangler is a 2005-2006 model with this engine?

A: Check your Vehicle Identification Number (VIN) on the driver's side dashboard. The 8th digit must be "S" to confirm this 4.0L AMC engine is correct for your Wrangler.  

Q: What warranty is provided for this engine?

A: Covered by 60-day warranty starting from delivery. File claims within 5 business days. Certain components need reprogramming by authorized dealer or ASE-certified technician. Extended warranty offered with post-installation notification. Disassembly without permission or incomplete reprogramming voids coverage. Best Use Auto Parts must approve all warranty repairs.

Q: What makes the 2005-2006 engine different from the 2000-2004 version?

A: The 2005-2006 4.0L AMC engine has updated engine management and fuel injection compared to 2000-2004 models. It includes improved emissions controls and enhanced cooling efficiency. Internal components are optimized for better durability. VIN 8th digit "S" confirms the correct 2005-2006 specification. These upgrades provide better reliability and lower maintenance. Always verify your VIN before purchasing.
