Manton High Rev High Boost Valve Springs 03-10 Ford 6.0/6.4L PowerstrokeNow you want to run higher boost in your 6. 4L Powerstroke, or maybe you're looking to move your power band further up the RPM range on your 6. 0L with a new camshaft, you're going to want to replace your valve springs to a set designed to hold your valves closed when they need to be closed, but still able to open when necessary. In a situation with the purchase of a new camshaft, the cam card will dictate the recommended spring ratings to ensure you

Now you want to run higher boost in your 6.4L Powerstroke, or maybe you're looking to move your power band further up the RPM range on your 6.0L with a new camshaft, you're going to want to replace your valve springs to a set designed to hold your valves closed when they need to be closed, but still able to open when necessary. In a situation with the purchase of a new camshaft, the cam card will dictate the recommended spring ratings to ensure you get the maximum performance out of the cam without floating valves.

Manton provides a full 32 spring set of high boost and high rev ready valve springs with 123lbs of seat pressure over the factory 80lbs, and 284lbs of open pressure. With that, you can feel confident that your valve train will open and close as it should, and not be a hinderance to your performance build.

Valve float can be a problem for those with high boost builds and higher RPM performance in the 2003-2010 Ford 6.0 and 6.4L Powerstroke, or for those with very little backpressure from the exhaust from hood stacks with large diameter piping. Valve float is exactly as it sounds, instead of fully closing during the engines cycle, the valve springs do not have enough force to hold the valve closed and thus, the valve "floats". You may see a dip in RPM, hear the engine stumble, or in extreme cases, find bent push rods during a tear down. You may experience a rattle in the valve train as well, which could be an indication of pending failure.

Prevent this with a fresh set of valve springs from Manton.

I would buy this twice!
Style: Sport, Size: 12in
This Chuckit! Dog Ball Launcher 12M Sport is the perfect product for the dog park! It makes games of fetch so much easier and more fun — the long handle gives great reach, so I can launch balls super far without even bending over, and our dog goes absolutely wild chasing them. It’s comfortable to hold, works smoothly with 2.5" dog balls, and really saves your arm and back if you’re doing a lot of throwing. The design is sturdy and reliable, so we can play for longer without worrying about it snapping or wearing out. If you spend time at the dog park or love playing fetch, this launcher turns a regular game into something even better — our pup gets twice the exercise and we get to enjoy every minute of playtime!

Caution can cause addiction
Style: Sport, Size: 12in
My dog has become addicted to tennis balls because of this! She sees the blue handle and she immediately loses her mind! I love it because I don't have to bend down as far to pick up the ball, which is amazing after 2 back surgeries.

12 " too short, no direction.
Style: Sport, Size: 12in
I got the twelve inch handle. It is too short and does not flex enough to release ball in right direction. Its almost impossible to aim and doesn't sent the ball far enough.

Perfect for offseason beach days
Winter in New England can be tough for a myriad of reasons, one being the difficulty in ensuring your high energy Labrador retriever is expelling enough energy and not climbing the walls. Luckily, this dreary time of year also means the beaches are open to dogs, and this toy is the perfect tool to make sure your furry friend gets their steps in. It is pretty easy to use and not too large for toting to the beach as it folds in half. The thrower itself is sturdy, although the included ball is a bit flimsy. Backup tennis balls are definitely recommend for public areas anyway. Once you’re done, you can bang or brush the sand right off for easy cleanup as needed. If you have kids, you get double bag for your buck because you can have them take turns throwing the ball or chasing as well. Definitely worth it’s value to tire everyone out and have some fun doing it.
