The stroker engine increases displacement from 4.0L to 4.6L by using a longer stroke crankshaft, resulting in significantly more horsepower and torque compared to the stock engine.

It's fully compatible with all factory automatic and manual transmissions from this era, as well as existing differentials and drivetrain components. This means you can upgrade to increased performance without requiring custom modifications or fabrication, making installation straightforward for experienced mechanics or professional shops.
How much more power does a 4.6L stroker engine produce compared to the stock 4.0L?
The 4.6L stroker engine provides a significant performance boost over the factory 4.0L engine. While the stock 4.0L typically produces around 190 horsepower and 235 lb-ft of torque, the 4.6L stroker delivers substantially more horsepower and torque throughout the RPM range.

Absolutely. The 4.6L stroker engine builds upon the proven reliability of Jeep's iconic 4.0L inline-six platform, which is renowned for its durability and longevity. When properly built and maintained, the stroker engine delivers enhanced performance while maintaining dependable operation for both daily driving and demanding off-road use. The increased displacement provides more low-end torque, which is particularly beneficial for rock crawling, trail driving, and hauling heavy loads without sacrificing the reliability that Jeep owners expect.
Do I need to upgrade other components when installing a 4.6L stroker engine?
The 4.6L stroker engine is designed to work with your existing 1991-1999 Jeep transmission, transfer case, and differentials without requiring mandatory upgrades. However, depending on your driving style and performance goals, you may want to consider upgrading certain supporting components, such as the cooling system, fuel injectors, or exhaust system, to maximize the engine's potential. Your existing drivetrain components will handle the increased power, but consulting with Golen Engine Service at 1-800-591-9171 can help you determine if any additional upgrades would benefit your specific build and intended use.
