Product Details

The COMP Cams SK68-235-4 Xtreme 4x4 camshaft kit is designed specifically for AMC and Jeep inline 6-cylinder engines, including the 199, 232, 258, and 4.0L variants. This hydraulic flat tappet camshaft features aggressive 210/218 duration specs optimized for off-road and rock crawling applications where low-end torque and throttle response are critical.

Camshaft Specifications:

  • Advertised Duration: 268°/276° intake/exhaust
  • Duration @ .050": 210°/218° intake/exhaust
  • Valve Lift: .444"/.465" intake/exhaust (with 1.6:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Hydraulic flat tappet design for durability and quiet operation

Complete SK-Kit Includes:

  • Xtreme 4x4 hydraulic flat tappet camshaft
  • Hydraulic lifter set (12)
  • Timing chain and gear set
  • COMP Cams assembly lube
  • Installation instructions
  • COMP Cams decals

This cam profile delivers excellent low-to-midrange torque with a smooth idle, making it ideal for street-driven 4x4 vehicles, daily driver Jeeps, and trail rigs that need reliable power at lower RPMs. The kit provides all essential valvetrain components for a complete camshaft upgrade in one package.

This was my first purchase from Autoplicity, I bought a HyperTech tuner for my truck, they had absolutely the lowest price of anywhere I looked by far. Only thing I could fault them on is that it took 3 days for the product to ship, a little bit long I feel for something that was in stock, but Ill overlook it since it was such a great price.

Thank you for having the items needed

I was very impressed at the timely fashion our order was shipped. I will be shopping with Autoplicity in the future.

Autoplicity was quick, and fast! the shipping was standard but arrived in five days! I would definetly recommend them!

I ordered a water pump from them and that Amazon was advertising as a Chrome pump. When I discovered it was not chrome, I asked to cancel the order which was prior to shipping notification. I was told by customer service it had already been sent and I would have to wait until the item was sent for a return to be processed. The return was sent back and all money was credited to my account as promised.
