Original-Equipment. The world’s foremost automotive brands put their confidence in Bilstein quality. Why? Because brand develops and series-produce suspension components in collaboration with Bilstein partners from the automotive industry. By placing your trust in Bilstein experience too, you'll be opting for the Bilstein driving experience when you exchange your suspension components.

Gas Pressure Technology. Over time, the mono-tube gas pressure technology developed by Bilstein has established itself as a standard in automotive construction. This technology involves keeping the oil in the absorber under pressure, which prevents it from foaming when temperatures and loads are increasing. As a result, full damping power is retained even when the system is placed under extreme stress, a feature that can be observed in the self-lowering piston.

Mono-tube Upside-Down Technology. The original and best: The original mono-tube gas pressure shock absorbers bore the Bilstein name, and we're still responsible for producing the best there is. Bilstein's mono-tube technology is the number-one choice in motorsports and series-production sports cars: no other type gives engineers the same freedom to choose the perfect installation location or position (e.g. Upside-Down technology).

Twin-tube Technology. The proven technology of a twin-tube absorber is applied in the vast majority of all vehicles. Bilstein‘s twin-tube absorbers, featuring "original equipment manufacturer” quality that has undergone rigorous testing, offer a marked improvement in driving characteristics with universal spare parts replaced in a timely and efficient manner.

Lots of fun at dog park!
Color: Blue Dog Ball Launcher with Squeaking Handle, Size: One-Size
Great for dogs who love to run and chase tennis balls! This one works with any standard tennis ball and I was surprised when I found out the handle also has a little squeeze toy sound which my dog absolutely adores.

Love this ball launcher! Just buy it!
Color: Blue Dog Ball Launcher with Squeaking Handle, Size: One-Size
These throwers are THE BOMB ! I've been using them for 4 years. The squeaker on it is a big hit at the dog park and with my dog. Gets dogs attention. Buy the squeaky chuckit balls to go with it. Easy to clean, holds up really well.

Squeaker Pinches Hand
Color: Blue Dog Ball Launcher with Squeaking Handle, Size: One-Size
I toss balls 50-75 feet into the air. Works our my dog. I can actually throw a ball over 150 feet, so the dog gets a good workout. The squeaker is unnecessary and it does pinch my hand on a long toss.
