BEEHIVE Springs
Why beehive valve springs? Beehive valve springs have been around since the days of the Wright Brothers Airplane; they have been used for over 100 years and are not new to the market. In fact Beehive valve springs are currently used in 90% of the OEM market to achieve the performance and desired valve control demanded by everyday driving conditions. PAC was first to release the new type of wire cross section known as Multi Arc or Ovate wire and has been successfully making millions of MA beehive springs per year.
Beehive valve springs have been known in the industry as having a lower mass at the retainer end thus allowing for better valve control. This is only partially the reason for the better valve control. Beehive valve springs are unique when it comes to coil spacing, rate control, and also using a PAC pioneered MA wire cross section (see below). Beehive valve springs are tailored for specific engines and specific camshafts using PAC RPD and are thoroughly tested using extremely sophisticated load check equipment.
With this technology PAC has been able to excel at providing the best valve train control with beehive valve springs to our customers and the worldwide market.
