Very Good Condition

Shows general wear associated with normal use over the course of a season or more but has been well cared for. Does not retain any of the "new look" but is in better than average condition. There is absolutely no sign of abuse. Cosmetic imperfections are typically visible. Examples include: scuffing, scratching, tiny paint blemishes, shallow dings/nicking, and normal shaft wear.


The King SpeedZone One Lengths irons by Cobra contain one repeatable setup and swing for more consistency between club to club. Also features matching weights that will create consistent feel throughout the set. Steel: KBS Tour 80 (4-6I), KBS Tour 90 (7-9I), KBS Wedge (PW-SW)


  • Consistent Set Up and Swing - 7-iron lengths promote one repeatable setup and swing. Allowing more consistency from club to club.
  • Matching Head Weights - 7-iron head weights and swing weights in every iron to create consistent feel through the set.
  • Optimized Lie Angles - Fine tuned lie angles to optimize trajectories in the long irons, mid-irons, and wedges.
  • Progressive Shaft Weights - Lighter long iron shafts to encourage easy launch while heavier wedge shafts promote more control into and around the green.
  • Cobra Connect - Track accuracy and distance on shots using the Arccos Caddie app on your Smart Device.



Excellent clubs

Review by Ariel B, 2 years ago.

“These irons are great - extremely forgiving, and the one length concept makes them swing really smoothly. Definitely improved my iron play. It does take a little getting used to if you are used to progressive length irons, especially on the shorter end, but I still highly recommend these irons.”

Used One Length Speed Zone Irons

Review by Brian T., 2 years ago.

“I bought a set of used Cobra Speed Zone One Length irons from I saved a good amount of money and I was pleasantly surprised when I received the clubs and saw that they looked virtually brand new. I have been playing Cobra One Length irons for about 3 years now and I absolutely love them. I play much much more consistent with these irons. Great purchase from”

Review by Frank C., 1 year ago.

“I had been looking at, and considering a set of these clubs for a while, and finally decided to make the purchase. I found the length of the clubs easy to adjust to. I like the weight of the clubs, and they look great. I do not find the top of the 5, 6 & 7 to be a problem at all. The club heads do not provide any more glare than any other irons that I have owned. I purchased the 5 - PW, and purchased a GW after receiving the set. Since then I have ordered a SW and LW to complete the set. I took the clubs to the range 1 time, and hit 2 buckets, and after the first bucket I found myself in a good place with the. Several days later I played my first round with these, and shot an 89. I was was happy with how easy they were to play on the course. To prove that these clubs are not for everyone my playing partners both asked to try them, and each had different reasons why they preferred their clubs. I did not notice any difference in ball height. I did notice that my distance was better, but could not give you any additional yardage differences. I like these irons, and look forward. to playing them for a full season to see how they, and hope I perform? Based on my initial results, I would. recommend them.”

“Keep It Simple Stupid - Thats what Im trying to do with switching to One Length Irons. So far at the driving range, the 5-7 irons are monsters hitting them long! The 8-GW still needs practice but will trust the science.”
