Skunk2 is proud to introduce its Lost Motion Assembly Kits for Honda’s B-series VTEC engines. Skunk2 Lost Motion Assemblies will fit any B-Series DOHC VTEC engine (Type-R/GSR B16A, B17A, B18C).
The Skunk2 Lost Motion Assembly is an advance spring device that is designed to put pre-load on the center portion of the VTEC rocker when it is in the unlocked position (when VTEC mode is disabled). During extended operating conditions, the contaminants in the oil will more than likely cause the piston to seize resulting in the VTEC rocker rattling when VTEC is not engaging or when the vehicle is in idle.
Each Skunk2 Lost Motion Assembly is manufactured exclusively from chrome silicone steel using the latest 3D CAD (Computer Aided Design) modeling and FEA (Finite Element Analysis) to ensure maximum optimization. Each chrome silicone steel spring features a hardened tip for added durability. Skunk2 engineers then tested and proved their design on the engine dyno as well as the race track.
The Skunk2 Lost Motion Assembly Kit replaces the factory piston-style LMA design with an improved design commonly found in newer generation Honda engines. Replacing LMA's are recommended when installing high-performance camshafts, and required when installing Skunk2 Pro Series and other high-lift camshafts.
Each Lost Motion Assembly Kit includes a set of 8 assemblies for an entire Honda DOHC VTEC B-Series 4-cylinder engine (Type-R/GSR, B16A, B17A, B18C).
• Equivalent to Genuine Honda P/N 14820-PCB-003 or Honda P/N 14820-PCB-305 (Retails at $257.76)
• Does not require use of shims like other lost motion assembly kits

Rubberized fun for your little ones
Pattern Name: Animals
If your pet baby loves squeaky toys, then these are right for them. Value for the money. Soft rubber, durable squeaker, and they bounce like a ball. I should say a ball that ricochets off of anything it bounces off of. Loads of fun for the little dogos.

Essential Dog Toy in "Our World"
Pattern Name: Funny Faces
I have bought ~a dozen of these packs over the last 7 years. Began when our cocker was a puppy and (with puppy teeth) prone to destroying each squeaky toy he loved. Searched on something like "non-destructible (or maybe durable) small dog squeaky toys)" and these popped up. Now, they're Bark Park playtime essentials. SO many pups there love them (and we let the "stealers" keep them and tell their parents how to get them. Every day we have Bark Park squeaky egg symphonies (one mini Aussie plays 3 simultaneously--2 by mouth; another with his foot) and chases, as ALL the doggos love them. They last a long time and can be washed (I use a toothbrush and block the hole w. a finger).

perfect size
Pattern Name: Animals
these are the perfect " Goldilocks " size for our 3 month old frenchie! Not so big he cant bite them and squeak them and not to small where i worry they could slip & choke him. just a heads up the squeak is pretty loud lol they also are very soft both in texture and in terms of being able to squeeze. thy can bounce a bit which he loves too. the green one for some reason is thicker and harder for him to bite & squeak so he doesnt really play with that one. so far they are holding up to his puppy teeth but i suspect if you have a aggressive chewer they wouldnt do so good. very happy with the purchase. and as you can see in my video so is our little man lol

Indestructible for our 8 pound Mi-Ki
Pattern Name: Funny Faces
Our small dog loves these and he hasn't been able to chew them up. He loves their unpredictable bounce and chases them all day. He also likes to sleep surrounded by them.
