Jeep Engines & Assemblies

Although it sounds a little cliché, your Jeep's engine is truly its central powerhouse. Once it grinds to a complete halt, your vehicle is sidelined for good unless you install complete new components. Count on 4WD.com to supply you with superior-grade, durable Jeep engine replacement parts that exceed OEM specifications.

Jeep Performance Parts From the Best Brands
Keeping your engine in top condition is a priority. Let 4WD.com supply you with first-class performance parts for the Jeep Wrangler from ATK North America, a manufacturer known for its expert craftsmanship, dedication to superior materials and quality control through extensive product testing.

We also stock products from Edelbrock, a specialty performance automotive components maker founded by a racing enthusiast in the 1930s. Both these makers produce overhead cams and cam block engines that come fully assembled and ready to install.
