Product Details

The COMP Cams K21-602-5 Thumpr K-Kit is a complete camshaft installation package designed specifically for Chrysler 383-440 cubic inch big block engines. This hydraulic flat tappet camshaft delivers an aggressive 243/257 duration profile that produces the signature Thumpr choppy idle and strong mid-range to upper RPM performance.

Complete K-Kit Includes Everything You Need:

  • Thumpr hydraulic flat tappet camshaft with 243/257 duration
  • Hydraulic flat tappet lifters engineered to match cam profile
  • High-performance valve springs for proper valve control
  • Valve spring retainers and locks
  • Valve stem seals for oil control
  • Timing chain set for precise cam timing
  • Assembly lube to protect components during break-in
  • Installation instructions and COMP Cams decals

The Thumpr series is known for its radical sound and excellent throttle response, making it ideal for street/strip applications where aggressive performance and attention-grabbing exhaust note are desired. This kit eliminates the guesswork of component matching by providing all valve train components engineered to work together for optimal performance and reliability in your Mopar big block.

Talked on the phone first and they were very helpful. Website was very easy to use.

My name is Doug Raber and I tell you the truth when I say autoplicity is a great site to shop for auto parts. The prices are low and the customer service is excellent.

Excellent price on the product and shipping! Ordered on Thursday night (after they closed) and they were shipped out Monday!

First time I've tried these guys. Had trouble getting this product from my normal source (backordered) but Autoplicity shipped quickly and had a better price too! You know I will be back! Thanks!

Great customer service. Prompt shipment and excellent prices. I will defiantly be ordering from them again. Just wish I would have found them sooner!!

Great price, fast shipping and the items was correct. A perfect transaction. Thank you!

I received my ARP head studs as described and on time with zero problems, and cheaper than anywhere else.Will use again!!!
