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

Very Good For The Price
Size: 6.2", Size: 6.2"
This came in today and it was very easy to put on the switch. It does have bubbles but they will disappear after a little while. I just got this switch used the other day and it did not have a screen protector. The screen had a few minor scratches, but the screen protector makes those scratches seem like they never even existed. The reactivity on the screen is very good. It is practically the same as it would be without the screen protector.

Super easy install!
Size: 7.9"
Super easy to install, you really can’t mess it up since the guide is so helpful! Plus you get extra shields just in case! I’ve had mines for months and it hasn’t cracked so the durability is great! Scratch free and smudge free!

The ultimate water bottle
Color: Iced Breeze, Size: 24 Ounces
I can’t believe I’m so excited about a water bottle. The design is amazing - I love that there’s no straw poking up but there’s still a straw sip function. I like that the carrying hook doubles as a lid locking mechanism. This bottle feels very sturdy but it’s sleek and easy to grab - I have small hands and it isn’t a problem for me to drink from with one hand. It’s also really nice that this bottle fits in standard couple holders both at the gym in the machines and in my car. The color selection is so fun and I am pleased that my bottle looks exactly as pictured. My water has stayed cold and my ice cubes frozen for over 12 hours now. Cannot recommend enough!

Keeps drinks cold all day
Color: Very, Very Dark, Size: 24 Ounces
We got this Owala bottle for our son to use as his everyday school water bottle, and it has been excellent. The 24oz size holds plenty of water for the school day without being overly bulky or heavy to carry around. The insulation works extremely well. Drinks stay cold all day long, even when the bottle sits in a backpack for hours. That’s probably the feature we’ve been most impressed with so far. It’s also been great for car trips since it keeps water cold for extended periods without needing constant refills. The design is really well thought out too. The built-in straw makes it easy to drink from quickly during class or while traveling, and the lid feels secure and leak-resistant when closed. It also has a clean, modern look that feels a little more premium than many standard water bottles. Build quality feels solid overall, and it seems designed to hold up well to everyday use from school, sports, and travel. Overall, this has been a fantastic everyday water bottle and definitely lives up to the hype. Keeps drinks cold, holds a good amount of water, and works equally well for school or road trips.
