King Cobra L4V Driver
Knowing what "L4V" stands for lets us know what Cobra's approach was in designing this driver. "L4V" stands for "Limit 4 Variables," and that means that Cobra designed a driver to hit the maximum specifications allowed by rule in four different areas. Those areas are:
- Clubhead Volume: It's 460cc in size, the maximum allowed by the USGA.
- Coefficient of restitution: The L4V driver has the USGA-maximum-allowed COR.
- Clubhead Dimensions: A clubhead can be a maximum of five inches from heel to toe, and must be less than that from face to back. This is usually written as 5" by ‹5". And those are the dimensions of the L4V. Its face-to-back measurement is as close as Cobra can get it to five inches without actually hitting it.
- Moment of inertia: 5900 is the measure of MOI that the USGA limit is set at, and the Cobra L4V hits that number. It is the first Cobra driver to max out at the current MOI limit.
The King Cobra L4V driver hits these specs through various design tricks, such as the use of multi-material construction; a carbon composite crown and sole sections, and tungsten weights, all of which call for the repositioning of weight to more advantageous places on the clubhead.
The driver head is paired with the Cobra/Mitsubishi Rayon Diamana Red Board graphite shaft. And with this driver, Cobra's "Speed Tuning" approach - gearing driver/shaft specs to golfers' swing speeds - includes what Cobra calls the "Dynamic Shaft Balancing System."
The L4V driver is available in X (extreme speed), F (fast) and M (moderate) models. The Dynamic Shaft Balancing System means that:
- X-Speed: The balance point of the X model shaft is shifted slightly toward the grip end, aiming at high launch and low spin.
- F-Speed: The balance point of the shaft is a little closer to the grip end than on the X-Speed model, aiming at high launch with low- to mid-spin.
- M-Speed: The balance point is closest to the grip end, aiming at high launch and mid-spin.
How do you know which model is right for you? Cobra's "Speed Tuning" suggestions are golfers with a swing speed of 104+ mph (average 265-yard-plus drives) should go with the X; swing speeds of 87-108 mph (225-275-yard average drives) need the F; swing speeds of 76-97 (average drives of 210-250 yards) need the M. Of course, you have to be honest in assessing your current driving capabilities to make good use of these parameters.
The X model comes in a 9-degree loft with a square face angle; the F in 9- and 10-degree lofts, with face angles 1.5 or 2 degrees closed; the M, lofts of 10.5 and 12 degrees with face angles of 2 or 2.5 degrees closed.
The King Cobra L4V drivers began shipping on Nov. 1, 2007. The MSRP at time of launch is $480.
