KGSP Filters (Fuel and Oil)
When using filters that are rough in texture, foreign materials can escape from the gaps
causing suction trouble. The KGSP filter uses genuine product level high-performance
filter paper. The dense structure can achieve high filtration efficiency that firmly captures
fine dust of under 20μm. The possibility of contamination is low, allowing use withconfidence. It has also accomplished the same usage time as the genuine product.

Rubber Crawler
KGSP rubber crawlers were reviewed from their basic structure,for quality improvement.
By reviewing the structure, we were able to improve derricking performance andincrease breaking power by 15%. In addition, riding comfort was improved by 20%
compared with the previous model by adopting a core metal arrangement, shape, andlag pattern in consideration of the elasticity of rubber while running.

Tabi socks that complete Japanese traditional attire with sharpness.
It is said that the prototype of tabi is two pieces of cloth sewn together. By changing the material and shape,these socks evolved over and over again.These tabi are still alive and well today at the worksite, with its snug fit
and underfoot grip.The evolution continues while taking advantage of inherited features not only for usability,
but also by reducing the burden on the sole and adding work safety features.
Kobelco has also evolved undercarriage features for comfortable footwork.
Undercarriage parts made of rubber requires high durability that is good on the road and to the person.
KGSP rubber parts maintain the quality of genuine products because they are developed without compromising.
They are excellent in abrasion- and damage resistance with consideration to staying firmly in place while driving,
yet easy to install.

Multi Next Engine Oil
The Multi Next Engine Oil DH-2 was developed to achieve an oil that would correspondto engines meeting the Tier4A and the Stage3B at a reasonable price. Continued use ofoxidized engine oil can damage engine parts, leading to serious failures. This product is
excellent in stabilizing oxidation and protects the inside of the engine by controlling oil
degradation. It also complies with the Tier3 and the Stage3A.
