YES, By maintaining a large inventory, we have the benefit of being able to serve our customers quickly and efficiently. No waiting months heads. No importation. No exchange rates or tariffs.
We stand behind our cylinder heads… and our customers. All cylinder heads come with a 13-month warranty. If warranty is required, the process is as follows. We require a video of the serial number on the front of the damaged head as well as the damaged area. We require up to 48 hours for our engineering department to assess the damage. Once we have determined the defect has been caused by a fault on our end, we will ship a new head out to your head office or the initial location it was purchased from.
Our cylinder heads are manufactured by Jereh Power Tech, the #1 SELLING in aftermarket cylinder head production in the USA for the past 5 years. Leveraging a state-of-the-art foundry, Jereh Power Tech implements a fully automated production line, including casting, machining, assembly, and packaging. Jereh Power Tech ensures precision and quality at every stage.
Each head undergoes advanced CNC machining and is subject to a rigorous inspection process, adhering to IATF16949 and ISO9001 standards. This includes comprehensive checks for casting integrity, thickness, and material composition, as well as vacuum, multiple oil/water passage tests to guarantee flawless delivery.
Jereh Power Tech continuous improvement ethos drives them to enhance cylinder head design for optimal performance and longevity, employing high-speed robotics for valve train assembly and thorough inspection to ensure product accuracy and reliability.
Yes, all of our cylinder heads are equipped with Stage 3 - Inconel Valves. Here's what that means and how it benefits your engine:
Stage 1 - Standard Valve:
Our standard cylinder heads come with all essential valve train components, designed for increased strength and a larger water passage size. This design enhances coolant flow, leading to more efficient heat transfer. Additionally, a higher nickel content ensures longer-lasting strength and durability.
Stage 2 - Inconel Exhaust Valve:
At this stage, we equip the cylinder heads with Inconel valves (either intake or exhaust, depending on the application). Inconel valves are renowned for their ability to withstand extreme temperatures and pressures, significantly enhancing engine resilience.
Stage 3 - Inconel Intake AND Exhaust Valves:
Our top-tier offering includes cylinder heads with both Inconel intake and exhaust valves. This setup is designed to handle the extreme temperatures, pressures, and stress generated by upgraded engines, ensuring peak performance under the most demanding conditions.
