Product Details

The COMP Cams 68-231-4 Xtreme 4x4 camshaft is specifically engineered for AMC/Jeep inline-six engines, including the 199, 232, 258, and 4.0L variants. This hydraulic flat tappet camshaft delivers a performance-oriented profile with 206° intake and 214° exhaust duration (advertised) that significantly improves mid-range torque and throttle response for off-road and 4x4 applications.

Key Features:

  • Advertised duration: 206° intake / 214° exhaust for enhanced torque curve
  • Hydraulic flat tappet design for reliable, low-maintenance operation
  • Optimized valve timing for improved off-road performance and trail capability
  • Designed specifically for AMC inline-six engines (199, 232, 258, 4.0L)
  • Xtreme 4x4 series grind tailored for four-wheel-drive vehicles
  • Maintains acceptable idle quality while delivering noticeable power gains

This camshaft is ideal for Jeep enthusiasts looking to extract more performance from their AMC inline-six engine without sacrificing street drivability. The Xtreme 4x4 profile provides excellent low-end and mid-range power characteristics that are particularly beneficial for rock crawling, trail running, and towing applications. Professional installation is recommended, and compatible valve springs and lifters should be verified for optimal performance.

Good price

Ordered a sling to store my roof rack. There was an issue with the supplier which was quickly resolved by the Autoplicity staff. Great customer service -- most responsive I've ever seen.<br><br>Best prices around.

Super easy to browse web site and find the product I wanted.<br>The price was unmatched.<br>Shipping was fast and cheap.<br>Super shopping experience.

Great prices, helpful customer service. Ordered 2 by mistake. And they got it cleared up real fast. Saved over $80 off retail. Will be ordering from the, again!!!!! <br>

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.
