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.

Small in size
Color: Grey
Very small, picture makes it look much larger than it is. Seemed more appropriate for a cat, and 6 month puppy figured it out in under 1 min. Not very challenging.

Extremely good quality. Soft ... SIZE UP if you want a looser fit. It is not "form fitting, or snug, but no extra. I am 5'5 190# 60 years old. This ... an XL will go to my daughter. I will be getting another 1-2 sizes up. We'll worth it!

best enrichment activities and a mental outlet
Color: Blue
I use this puzzle toy regularly with my two dogs, and it’s been a great way to provide mental stimulation while slowing down treat time. The sliding compartments are easy for dogs to understand but still challenging enough to keep them engaged. They quickly learned to use their noses and paws to uncover the hidden treats. It works well as both a slow feeder and a boredom buster, especially on days when outdoor activity is limited. The toy feels sturdy and stays in place during use, even when both dogs are actively working through it. I like that it encourages problem-solving without being overly frustrating. This is best for dogs who enjoy enrichment activities and need a mental outlet. For very strong chewers, supervision is still important, but as an interactive feeder and skill-building toy, it’s been a useful addition to our routine.
