Valve springs are one of the most critical and overlooked components in your engine. Proper selection of the valve springs begins with identifying the application then selecting all the necessary componentry that will complement the springs in order for the engine to reach its full potential. Unfavourable results will ensue when installing a cam that will have an 8000rpm limit with the incorrect springs and supporting parts. Improper selection of the valve springs is one of the most common causes of engine failure.

One of the biggest valve spring manufacturers in the States, a specific array of valve spring kits has been developed to work in conjunction with the latest range of next gen GM LS camshafts and all other aftermarket cams in the industry. Each kit is tailored for use with specific camshaft grinds and is available in a beehive, conical or cylindrical dual spring style setup.

Each kit is equipped with everything required to upgrade your valve-train when installing an aftermarket camshaft. All components are manufactured from high quality materials to ensure durability, and performance is maintained even in the harshest environment.

Just what I was looking for

Finally, a pair of boy shorts that fit well, have a gusseted crotch and are so comfortable. I hope they keep making these because they are great.

Buy them!
Color: (6 Pack) 2-black 2-beige 2-white, Size: Large
Better than I was expecting! Its hot and humid here, while also being windy, so wearing sundresses is necessary, but scary. Lol These cover everything and are so silky soft. They're also stretchy enough for you to not feel like you're wearing anything at all. So comfortable. 10 out of 10.

Very comfortable, right length
Size: Large, Color: Black,grey
This product arrived as described. I like the trunk length, not the boxer brief length. They are comfortable. Hold up well when worn and washed. I don't seem to sweat as much. These were ordered to replace ones ordered about 2-3 years ago due loss of weight, had to down size. The waist band doesn't roll as like other brands.
