420 HP of power, 1,075 pound-feet of diesel torque, and an oil change interval of up to 15,000 miles are every adventurous man's dream. Those are some of the characteristics of the famous 6.7 Cummins engine. However, no matter how tough an engine is it still needs protection as a result of varying operating parameters. This article offers a perspective on why SPELAB's 6.7 Cummins valve cover is reliable.
The Cummins 6.7 engine is powerful but some problems may arise with extended use, especially under constant heat and extreme engine operating conditions. Ordinary valve covers often do not offer the expected protection and continuous engineering is absolutely necessary to achieve better protection performance. The manufacturer has actually provided an OEM valve cover, unfortunately, in many cases, it does not offer the expected performance. That is why relying on "third-party" valve covers can be a solution.
There are several kinds of metal materials that are often used for valve cover fabrication but cast aluminum is by far the most popular one. It provides a significantly greater advantage over other metallic materials with regard to its durability at very high temperatures and over long periods of time. Cast aluminum is always in the equation when engineers strive to find a material with good resistance to high temperatures while still being easy to shape.
Such is the case with SPELAB's 6.7 Cummins aluminum valve cover. The valve cover was designed with an enhanced design, adding a sleek look to Cummins’s engine bay. With its cooling fins and special coatings, every Cummins owner can put their worries to rest, even if their engine is often put through extreme situations. It is a billet aluminum valve cover made by SPELAB that is designed for multiple purposes, whether it is for racing purposes, heavy-duty tasks with a long duration, and also for just a cooler engine bay look.
Weighing about 7 kg, the valve installation does not compromise the performance of the truck. And there is no need to worry about the imprecision of workmanship as the Cummins valve cover is manufactured with CNC machines. All the details of the curves are precisely measured and well-crafted, making forming errors impossible.
Why Billet aluminum if cast aluminum is good enough?
Cast aluminum is made by pouring molten aluminum into a mold but the drawback is the level of precision that may vary. On the other hand, aluminum billets are made not from molten aluminum but from solid aluminum blocks through forging and machining processes so their durability is certainly higher. Usually, aluminum billets are used for products that require a high degree of precision, such as engine cover covers. Inaccuracies in design can lead to significant performance degradation so from metal material selection to machining processes must be carefully planned.
SPELAB's 6.7 Cummins Billet aluminum valve cover is the answer for every owner of a powerful diesel engine to protect their "darling" in a variety of conditions. Its durability, design, and relative affordability are reasons that are hard to argue with.
