Single Tube Damper Design

  • Mono tube dampers allow for more accurate and stable control and adjustment of dampening. Lower ride height and center of gravity gives a more stable ride.

Dust Boot

  • Protect the shaft from the flying stones.

PNE Coating

  • Using this special surface coating provides 5 times better durability over standard galvanising. This prevents build-up around the threads of the adjustment areas allowing for easier height adjustment.

M Shaft (?46 normal type)

  • With the new design of cylinder shaft since the HIPERMAX M-1, MAX IV increased the cylinder shaft size to have a firm damping even at a little stroke range by optimizing the oil pressure characteristic. We mainly adopted this to the rear damper that can have a better driving experience.

Adopted Pillow Ball Upper Mount

  • For more accurate and sharp steering.

New Design Needle

  • Newly designed needle has been used to revise the very low speed and middle and high speed dampening which is key to a comfort ride.

Reduction of Unsprung Weight

  • In order to reduce unsprung weight, bracket, ride height adjusters and lock nuts are made from aluminium. (Not for all vehicles)

30 Step Damping Force Adjustment

  • 30 levels of dampening adjustment allow fine tune adjustment for street, circuit winding roads, highway, or the weight of the vehicle.

Best and most durable toy for our German shepherd
Size: Medium, Style: Ultra Tug, Size: Medium, Style: Ultra Tug
We have a German shepherd. This is our 2nd purchase. The first one was her first and favorite toy. We still have the first one. But the strap broke (after a year) bc we didn't realize she hid it under blanket, and she chewed it in half. But after a year of hard play, the strap was worn out. She still plays with her ball, and often carries it with her on her walks. It throws well and I love not having to pick up a slobbery ball. The ball is soft, durable, safe, and easy to play with.

Cord is not durable. Not for unsupervised play.
Size: Medium, Style: Ultra Duo Tug
My dog loves this toy and chewed through the tether in about 15 minutes, making it pretty useless as a tug toy. So the cord is not durable as stated. This is not for dogs who love to chew. Also, it is a bit smaller, much more squishy and chewable than a tennis ball, and I was worried she would chew it apart and that it might get stuck in her throat without the tether, so I took it away, much to her disappointment.

Puppy's favourite, but not built to last.
My puppy absolutely adores this tug-of-war ball! However, I have to mention the durability—it started fraying after just a few days of use. While it’s still usable, the material doesn’t hold up well to enthusiastic chewing and tugging. If your pup is a strong chewer, this might not last long. That said, for the price and the joy it brings my puppy, I’d still consider buying it again—just with the expectation that it’s more of a short-term toy. Great for light play, but not built for heavy-duty tug sessions.
