STEMCO QwikKit king pin kits protect fleets as well as other vehicles on the road with higher impact strength, more consistent lubrication, and up to four times the longevity of OE or other aftermarket competitors’ king pins. In addition, STEMCO QwikKits install in a fraction of the time of a reamed king pin. Each STEMCO QwikKit product is tested to take the abuse of the road and is backed by more than 50 years of experience in king pin technology, extensive on-site training for technicians, and a trusted warranty program.
Not all king pins are created equal. Only STEMCO’s proprietary king pin design allows an optimal flow of lubrication to high-wear areas, safeguarding investments, and ensuring long king pin life. STEMCO’s proven configuration of lip seals and self-cleaning bushings deliver clean grease to the pin, which then carries debris and contaminants outward from the pin and bushing.
The high-performance materials used to fabricate each QwikKit are selected to provide an ideal balance of strength and resilience between the pin and bushing. This precise combination of materials is found exclusively in STEMCO QwikKit king pin kits, so only STEMCO products will exhibit the durability and reliability the market has come to expect. When removing a STEMCO QwikKit king pin from the truck, there may be a dark spiral pattern in the steering spindle bore. This is evidence of the pumping action that is continually keeping the king pin lubricated and expelling contaminants outward.
Each component of the STEMCO QwikKit is part of a proven system integrally designed not just for rapid installation, but superior performance, and better durability. Providing longer-life from materials selection to design to manufacturing. STEMCO’s lip seal performs the critical function of retaining lubrication on one side and keeping contaminants out on the other. STEMCO hardens their lock pins to ensure the king pin is held more securely in the axle, reducing the opportunity for an out-of-round condition that could result in loose steering control and increased tire wear.
STEMCO No-Ream steel bushings and pins are grooved to provide an optimal stream of lubrication to high-wear areas holding 300% more grease than standard king pin sets.
Proprietary high-chrome, high-carbon tool steel is found only in STEMCO king pins kits, balancing strength and resilience. This means it can withstand the constant turning and pounding placed on the steering knuckle and axle over the life of the vehicle.
Everything about the QwikKit is designed for performance, durability and safety, including:
Replacing traditional king pins can sometimes be a long, greasy process. The proprietary design of the QwikKit king pin allows it to be installed by technicians in a fraction of the time of a traditional OE or aftermarket king pin. This allows maintenance teams to move to their next project quicker and eliminate the need for the next service job.
For more than 40 years, STEMCO has tested STEMCO QwikKit king pins versus OE king pins and aftermarket competitors. This has helped them refine their methods for controlling lubrication and materials selection. This testing, combined with proprietary material, manufacturing and design science, provides the foundation for pin and bushing performance that yields up to four times the life expectancy of traditional king pin kits, which include bimetal, bronze, and composite bushings.
Based on these test results, STEMCO have engineered design modifications to the bushing that lead to better performance and extended life.
The STEMCO QwikKit king pins lasted four times longer than original equipment and substantially longer than aftermarket competitors.
STEMCO stands behind their products with one of the best warranties in the business, engineered so that warranty is rarely necessary. The STEMCO QwikKit has a record of virtually no warranty returns–less than two claims per 10,000 kits sold.
STEMCO’s technical support team is available for all STEMCO products including exceptional expertise in king pin products. With over 100 years of combined QwikKit knowledge and the ability to help with installation, VIN number crossovers, and identifying the proper kit, STEMCO offers unparalleled support Based on these test results, STEMCO have engineered design modifications to the bushing that lead to better performance and extended life.
STEMCO empowers customers, sales staff, and technicians with a robust training program used by over 50,000 technicians annually. STEMCO offers on-site training, in-depth help, and District Service Managers to ensure the roadways stay safe. The king pins are the most crucial components of the steer axle, so proper training and installation is critical. At any time, expert help for STEMCO king pins is only one call away through live technical support.
