Building the line of Stealth Turbos meant designing a turbo that's safe to tow with, fun to drive every day and a class leading competitor. If you think street-able, clean, stealthy power is cool, then this is the turbo for you.
Duramax Tuner's custom-built Mach 2 (67mm) compressor wheel is specifically designed to maximize peak power while maintaining a wide, useable powerband. To fit the monster compressor wheel, they developed a unique, OEM appearing, anti-surge ring, which nestles in the factory compressor cover. Matching the class-leading compressor performance meant updating the center section which is fitted with a 360-degree thrust bearing to increase reliability under heavy load transitions. The wastegate was even updated to make sure you have the most amount of power and the quickest spool-up.With the compressor side and center section put together, a turbine wheel and exhaust housing upgrades had to be made. The LB7 Stealth Mach 2 (67) features the largest turbine available in an IHI-style (stock LB7 turbo) frame. This dramatically reduces drive pressure and allows for serious power production even at high RPM where the IHI typically falters. This monster turbine helps you achieve as close to a 1:1 ratio between drive and boost pressure, which not only helps make more power but also manages EGT's (Exhaust Gas Temperature) under heavy load.

No more sunscreen in our hair!
Style: NEUTROGENA SHEER ZINC, Size: 1.5 Fl Oz (Pack of 1)
The only kids sunscreen stick I've found that actually glides on. After struggling with too-hard sticks and messy lotions, this is so easy to apply to my wiggling toddler. And the large size makes application to the whole body a breeze. This is perfect to keep in the diaper bag and quickly reapply for the whole family.

Great post bike ride
I have been using this Coola recovery mist for a few weeks off and on after bike rides if I can't get a shower immediately. It provides relief to my face and shoulders from the sun and drying sweat. If I use this after washing my face at the end of the day, it helps hydrate my skin just enough if I don't feel like using my heavier creams and moisturizers. Not saying one replaces the benefit of another, but if I'm looking for something lighter this relieves the tension of tight skin perfectly. I am planning on taking this for a week long camp out this summer and plan on taking this to help relieve my skin. Yes, it definitely smells a bit like chlorine but it goes away quickly. The only thing I really don't like is the pump sprayer is really not a mist, it's more targeted and instead of misting the product is little droplets it's a dense spray in a smaller area.
