Introduction
Many car enthusiasts and Jeep owners are familiar with the term “4.0 stroker motor”. It is a popular upgrade for Jeep vehicles that can provide more power and better performance. In this article, we will discuss what a 4.0 stroker motor is, how it works, and why it is a popular choice for Jeep owners.
What is a 4.0 Stroker Motor?
A 4.0 stroker motor is an engine upgrade that involves increasing the displacement of the Jeep’s original 4.0-liter engine. The upgrade involves replacing the stock crankshaft and rods with stronger and longer ones to increase the stroke length. This increases the engine’s displacement from 4.0 liters to 4.6 or 4.7 liters, depending on the specific upgrade.
How Does a 4.0 Stroker Motor Work?
A 4.0 stroker motor works by increasing the engine’s displacement, which results in more power and torque. The longer stroke length allows for more fuel and air to be drawn into the engine, which increases the engine’s output. The upgrade also involves replacing the stock camshaft with a performance camshaft that is designed to work with the longer stroke length.
Why is a 4.0 Stroker Motor Popular?
A 4.0 stroker motor is popular among Jeep owners because it provides a significant increase in power and torque without requiring major modifications to the vehicle’s drivetrain or exhaust system. The upgrade is also relatively affordable compared to other engine upgrades, making it a popular choice for those on a budget.
Benefits of a 4.0 Stroker Motor
The benefits of a 4.0 stroker motor upgrade include increased horsepower and torque, improved throttle response, and smoother acceleration. The increased displacement also allows for better low-end torque, which is particularly useful for off-road driving. Additionally, the upgrade can improve fuel efficiency when compared to other engine upgrades that require more fuel to produce more power.
Installation Process
The installation process for a 4.0 stroker motor upgrade can vary depending on the specific kit used and the Jeep model. Generally, the process involves removing the stock engine components and replacing them with the upgraded components, including the crankshaft, connecting rods, and camshaft. The installation process can take several days and should be done by a professional mechanic.
Cost of a 4.0 Stroker Motor Upgrade
The cost of a 4.0 stroker motor upgrade can vary depending on the specific kit used and the installation process. Generally, the cost of the kit ranges from $2,000 to $4,000, while the installation can cost an additional $1,000 to $2,000. However, the cost can vary depending on the specific Jeep model and the mechanic’s labor rate.
Compatibility with Jeep Models
A 4.0 stroker motor upgrade is compatible with most Jeep models that have the original 4.0-liter engine. The upgrade can be particularly useful for Jeep models that are used for off-road driving, such as the Jeep Wrangler and Cherokee. However, it is important to ensure that the specific kit used is compatible with the Jeep model and year.
Conclusion
A 4.0 stroker motor upgrade is a popular choice among Jeep owners who want to increase their vehicle’s power and performance. The upgrade involves increasing the engine’s displacement by replacing the stock crankshaft and rods with longer and stronger ones. The upgrade provides benefits such as increased horsepower and torque, improved throttle response, and smoother acceleration. The upgrade is also relatively affordable compared to other engine upgrades and is compatible with most Jeep models.
