Trust The King Pin Experts With This Vital System.

Protect your fleet and other vehicles on the road with STEMCO Kaiser™ QwikKit® King Pin Kits. With higher impact strength, improved durability and more consistent lubrication, QwikKit King Pin Kits last up to four times longer than OE or aftermarket king pins. They also install in a fraction of the time of reamed king pins.

Designed For Durability.

Not all king pins are created equal. Only STEMCO’s proprietary king pin design allows optimal lubrication in high-wear areas, safeguarding fleet investment and ensuring long king pin life. STEMCO’s proven configuration of lip seals and self-cleaning bushings delivers a precise stream of clean grease to the pin, which then carries debris and contaminants out from between the pin and the bushing.

Cut Down On Shop Time.

Replacing traditional king pins can sometimes be a long, greasy process. The proprietary design of the QwikKit king pin allows technicians to install it in a fraction of the time of a traditional OE or aftermarket king pin, so a fleet can move on to the next project quicker.

Tested For Toughness.

For more than 40 years, STEMCO has tested STEMCO Kaiser QwikKit King Pins versus OE king pins and aftermarket competitors. This has helped us refine our methods for controlling lubrication and materials selection. This testing also means our customers can be confident they are entrusting their commercial vehicles to the most durable, longest lasting and trustworthy king pin on the road.
