DSS 88-91 Honda Civic/CRX EF w/K-Series Conversion (EFK2 Motor Mounts) 700HP Axle - HY4004X4

If you're swapping a K-series engine into your 1988-1991 Honda Civic or CRX using the EFK2 motor mount kit, you're going to need axles that can handle the power and the new drivetrain geometry. The Driveshaft Shop's HY4004X4 axle is built specifically for this popular conversion, ensuring your K-swapped EF chassis can put down up to 700 horsepower reliably.

These aren't your average axles. The Driveshaft Shop builds these with a larger, stronger inner CV joint designed to mate with the K-series transmission output shaft. The outer CV joint is also beefed up to handle the increased torque and angle. The axle shaft itself is made from a high-strength alloy, heat-treated for maximum durability. This combination means you get a solid connection from your transmission to your wheels that's built to withstand the demands of a high-performance K-series engine. They're designed as a direct replacement for the factory axles, making installation straightforward once the engine swap is complete.

When you're pushing serious power through a K-series swap, the drivetrain components are often the first to show stress. Investing in a well-built axle like this from The Driveshaft Shop is crucial for ensuring your project stays on the road and performs as you expect. Make sure you have the correct EFK2 motor mount kit installed, as these axles are designed to work in conjunction with that specific setup.
