Skunk2 is proud to introduce its Pro Series XP (Extra Pressure) Racing Valve Spring Kits for the Honda B-series VTEC engines. Each kit includes Skunk2's high-quality race-proven dual valve springs that are the result of nearly two decades of racing and engine building experience. 'XP' features a higher seat pressure for turbocharged and extreme high RPM motors. This spring has a seat pressure of 93lbs @ 1.320 in. while keeping the coil bind height for higher lift camshafts. Each Pro Series XP Racing Valve Spring is manufactured exclusively from super-clean, chrome-silicone wire milled in Japan. By using inner and outer springs mated together through a slight interference fit and with differing frequencies, Pro Series XP Racing Valve Springs are able to prevent valve float and maintain valvetrain stability at engine speeds in excess of 11,000 rpm. Wound by a premier North American winder, our Pro Series XP Racing Valve Springs retains its durability and strength that results in improvement to the extreme fatigue limit of the wire and enhanced resistance to load loss. Pro Series XP Racing Valve Springs are engineered to handle the demands of extreme-lift camshafts operating at prolonged, high-rpm use at championship-level racing. Skunk2's Pro Series XP Racing Valve Spring's for the Honda's B-series VTEC engines are simply the best on the market. Pro Series XP Racing Valve Springs have been tested at speeds exceeding 11,000 rpm on our engine dyno, street, and the race track. Our superior, Japanese-milled, super-clean chrome silicone wire is 100-percent eddy-current inspected prior to coiling. Next, they are heat-treated, shot-peened, and chemically polished for strength and durability. A special nitriding process concludes Skunk2's rigorous manufacturing process. The end result is a lightweight valve spring that safely accommodates high-lift camshafts and features superior resistance to load loss, even under extreme operating conditions.This Part Fits:

Heavy duty chewing, not heavy duty dropping
Size: X-Large, Color: Textured Ring
My super chewer loved this toy, great shape, provided long lasting entertainment. However, when he dropped it from his mouth onto our epoxy flooring (not a far drop as he’s only 50lbs) one chunk broke clean off at the 2 smaller joints. Although we kept the larger piece for a while, a similar drop a week later broke it again. Considering this is fairly inexpensive, I wasn’t expecting it to be indestructible. It’s just strange how it broke. Will probably buy again to test one more time.

My dog loves these things
Size: Large, Color: Femur Bone
My dog loves these things. They don't smell at all. It was a great price. It's big enough for my Frenchie. It's pretty durable but he is able to gnaw it rough so I do have to replace them periodically.

Doggo Approved
Size: X-Large, Color: Textured Ring, Size: X-Large, Color: Textured Ring
About as indestructible as it gets. It's just very hard molded material. I always make sure to wash the dog toys before letting them play, who knows where they come from. Picture is after hours/days of the built playing with it

Old Faithful
Size: Large, Color: Wishbone, Size: Large, Color: Wishbone
AmStaf/Lab loves this product. I am still concerned about him ingesting the sharp little pieces he gnaws off, but he seems OK after three months of using these. Tried the Nylabone natural/wild products but they are not usable as a "chew" and disappear within minutes, nay seconds!
-So here I am back to the "strong chew" wishbone product which makes my dog happy and keeps him busy not eating my shoes. (Be warned though, these are worse than Legos if accidentally stepped on!)

Perfect for small dog that likes to chew
Size: Small, Color: Textured Ring
Just got this today (small size for my 15 lb dog) and she loves it. Perfect size for her small mouth and teeth. Keeps her busy and even tires her out and rests a while, Between this type of dog toys and ones that squeak she is having a great time
