Supertech is proud to introduce its Lost Motion Assembly Kits for Honda’s B-series VTEC engines. Supertech Lost Motion Assemblies will fit any B-Series DOHC VTEC engine (Type-R/GSR B16A, B17A, B18C).

The SupertechLost 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 Supertech 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 steel and carbide coated tip for added durability. Supertech engineers improved upon other LMA on the market by applying their decades of spring experience to this quality replacement.

The Supertech Lost Motion Assembly (LMA) kit replaces the factory piston-style LMA design with an improved spring design commonly found in newer generation Honda engines. Replacing LMA's are recommended when installing aftermarket camshafts and required when installing high-lift camshafts.

Each Lost Motion Assembly Kit includes a set of 8 assemblies for an entire Honda B-series VTEC engine and are compatible with all camshafts. When using camshafts with +12.5mm lift, LMA's are an absolute must, and Supertech Lost Motion Assembly springs are 3 percent stiffer than ITR springs.

Complete set of 8 LMA springs.

Engine Application: All B-series VTEC engines (B16A/B17A/B18Cx).
No shim/spacers/washers required.
Not compatible with non-VTEC B-series engines

Not for super chewers
Color: Hambone Super Chewer, Size: M/L
Had to take it away from my dog the same evening I gave it to him because a chunk came off. I did not want him to choke on the pieces.

A favorite for my boys!
Color: Hambone Super Chewer, Size: M/L
My dogs love this toy, it satisfied their need to rip up a toy and still allowed them to play long after the top layer was torn apart to enjoy! It bounces well and has still held up with my chewers, this is still one of my dogs favorite toys to play fetch with!

Great toy
Color: Hambone Super Chewer, Size: M/L
My dog loves this toy so much. He's not quite so aggressive with his chewing, now that he's getting older, but this toy lasted through his younger years, and recently started to show signs of wear. He was so sad when I threw it out, that I had to replace it. Glad it still exists - we got the first one probably 5 years ago.

Great for heavy chewers
Color: Hambone Super Chewer, Size: M/L
Our dog is a hard core chewer! This toy is very durable. Even the covering has lasted. We assumed we would need to take the cover off right away but it’s still going after 3 months. It’s definitely chew resistant

Great treat dispenser
Color: Hambone Super Chewer, Size: M/L
Great rubber toy, the outside fabric did not last long, so glad that it is a treat holder/dispenser otherwise it would have been done for in about 10min. The opening for the treats is pretty small so can only fight thinner broken up treats. Great for larger dog that likes to dissect her toys, keeping her entertained longer and no fluff all over the house
