🚀 COMP Cams SK68-232-4 Xtreme 4X4 Hydraulic Flat Cam Kit for AMC 199-258/4.0L - Unleash Extreme Performance! Review

My analysis of this product showed that it lacks quality performance and durability. The hydraulic kit did not show any significant improvement in my car's engine power and speed. The installation process was also quite complicated and required professional assistance. On the other hand, the kit did come with a detailed instruction manual which was helpful. Overall, I would not recommend this product for serious automotive enthusiasts.

I have a 2000 wrangler tj that I rebuilt. It says it won't work, but the 4.2 timing cover, camshaft bolt and spring pin with correct timing will fit as it came from the factory. Also use heavy duty Mopar valve springs to prevent valve movement. Sounds like a dragster idling lol. Works harder and adds tons of torque.

Great camshaft for a high mileage stock engine. Generates more power at rated speed. Doesn't pull at idle like a stock cam, but does pull above 1800 rpm. I use the original Carter BBD with the stepper motor disabled. I have to say mine doesn't work very well with the stock valve train and it seems that the standard length tappets are too short. A longer push rod at 0.050 might help.
