Our premium kits contain all elements required for a full OEM quality service of your lower shock. Our dedicated off-road design of needle bearings, collars, pins and dust seals are specifically manufactured in order to reach the stringent OEM quality requirements, in terms of materials, dimension tolerances, hardness and surface roughness.
Pins are precision turned, induction hardened and polished in accordance with tolerances set by vehicles' manufacturer. The material employed is SAE52100 high grade bearing steel, it is hardened to above HRC60 and then the raceway is precision grounded.
Collars are precision turned, polished, hardened to HRC48 and then Zinc plated. The material used is automotive standard SPCC steel.
Dust seals are made of Nitrile Butadiene Rubber and strictly molded to exact OEM specifications. They prevent abrasives, corrosive moisture and other harmful contaminants from entering bearings.
