Product Details

The COMP Cams Xtreme 4x4 K35-243-4 is a complete hydraulic flat tappet camshaft kit engineered specifically for Ford 351W small block engines. This comprehensive K-Kit delivers aggressive performance with 226° intake and 234° exhaust duration, making it ideal for off-road, truck, and 4x4 applications where low-end torque and throttle response are critical.

Complete K-Kit Includes:

  • Hydraulic flat tappet camshaft with optimized 226/234 duration profile
  • Hydraulic lifter set matched to cam specifications
  • High-performance valve springs designed for increased lift and pressure
  • Hardened steel retainers for durability under demanding conditions
  • Precision valve locks (keepers) for secure valve train operation
  • Valve stem seals to prevent oil consumption
  • Timing chain set for accurate cam timing
  • Assembly lube for proper break-in procedure
  • COMP Cams decals and detailed installation instructions

Performance Characteristics:

  • Designed for 4x4 trucks, off-road vehicles, and towing applications
  • Produces strong low-end and midrange torque for improved throttle response
  • Aggressive idle quality with enhanced sound
  • Recommended operating range: 1,500-5,500 RPM
  • Works with stock torque converters and rear axle ratios

This all-inclusive kit eliminates the guesswork of component matching, ensuring all valve train components are engineered to work together for optimal performance and reliability. The Xtreme 4x4 series is specifically designed for enthusiasts who demand improved power delivery without sacrificing street manners or low-speed drivability.

Great service, awesome prices, incredibly fast shipping. A++ I would absolutely suggest you to my friends and family

quick response and unbelievably CHEAP prices.

Easy

Ordered a set of 5 steel wheels, distributor messed up and only sent me 4. 5th wheel is taking a good couple weeks to arrive due to the distributor messing up the shipment. Autoplicity did make things right and I can honestly say now I would recommend them.

- Updated review -<br>Autoplicity.com contacted me after my original review and admitted to making a mistake with my order. They have refunded my shipping and I am happy now.<br><br>- Original review -<br>After 18 days the part finally arrived. The filter appears to have been sent directly from K&N, but I ordered on the 20th of June, yet the packing date that K&N Engineering Inc. shows is July 3rd.

Prompt shipping and good price. Was one of the few online retailers that had the item I was looking for. Would buy from again.
