Buying Guide

Choosing the right crate engine for your Jeep 4.0 involves several considerations. Here’s what to keep in mind:

  • Intended Use: Are you using your Jeep for daily driving, off-roading, or both? This will determine the level of performance you need.
  • Budget: Crate engines range in price from affordable remanufactured options to high-performance stroker engines. Set a budget before you start shopping.
  • Mechanical Skill: Are you comfortable installing the engine yourself, or will you need to hire a mechanic? This will influence whether you choose a complete drop-in engine or a long block.
  • Warranty: Check the warranty offered by the manufacturer. A good warranty can provide peace of mind and protect your investment.
