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.

Good quality for a decent price point
Excellent set for a reasonable price. Eye serum is not good for those with super sensitive skin (like those prone to eczema), but otherwise works for us!

So far I like it
I bought this combo because I have used the ordinary before and liked the results. So far I’m not a fan of the lotion, feels a bit too thick for my liking. But other 2 products so far are making my skin look brighter and hydrated. I didn’t break out at first with the oil because I’m sensitive to too much oil but my skin adjusted to it. Definitely value for your money.
