Cobra Darkspeed Irons Specs: Full Loft, Lie & Length Chart (2024)
The Cobra Darkspeed irons come in two builds: Standard (progressive variable length) and One Length (every club at 37.25″). The tables below give the exact lofts, lie angles, lengths, and offsets for both versions. After the specs, you will find a decision sequence to help you choose the right build and know when to consult a fitter.

Applying the Numbers: Standard vs One Length
Having the specs is only useful if you know how to use them to choose the correct set. Follow this sequence.
1. Compare lofts to your current set.
The Standard 4‑iron at 18.5° is strong — it matches many dedicated driving irons. If your current 4‑iron is 20° or higher, expect a distance jump but also a lower launch. The Standard 7‑iron at 27° is typical for a game‑improvement iron but still strong compared to a blade (34°). If you already launch high, strong lofts may work. If you struggle to hold greens, ask a fitter about bending clubs 1° weak.
2. Check the offset progression.
Standard offset drops from 5.4 mm in the 4i to 0.8 mm in the SW. That is a clear fade‑bias reduction as clubs get shorter. If you tend to hook long irons, the higher offset in the 4–6 irons helps square the face. If you slice, you may need even more offset — that points toward a different model or a custom order.
3. Decide on length consistency.
If you have a consistent swing plane and struggle with variable‑length distances, choose One Length. Every club matches the 7‑iron length (37.25″) and lie angles near 63.5°. You can set up identically for every shot. Note that One Length lie angles decrease as lofts get higher (65° in 4i down to 61.5° in GW), which is opposite to Standard. The short irons will sit more upright relative to your stance — you may need lie testing. If you want natural distance gapping and better turf interaction through the bag, stay with Standard. The progressive length and increasing lie angles (62° to 65°) help the clubhead glide through the turf on short irons and stay level on long irons.
4. Verify with a launch monitor.
Hit at least five shots with a Standard 7‑iron and a One Length 7‑iron (both at 27° loft). Compare carry distance, peak height, and dispersion. Success signal: the distances between your 6‑iron and 8‑iron gaps should fall within 10–12 yards. If any gap is wider than 15 yards, the set may be poorly matched to your swing speed or attack angle.
5. Recognize failure modes.
One common issue is wrong lie causing directional misses. If you buy One Length without a lie check, you may see consistent left or right misses in the long irons (upright at 65°) or short irons (flat at 61.5°). Symptom: your 4‑iron draws while your GW fades. Solution: see a fitter to have the lies bent — the heads are forged and adjustable. Another issue is ignoring offset causing hook or slice pattern. A player who slices may buy Standard assuming offset helps, but the 4‑iron offset (5.4 mm) is moderate; if the slice persists, the set will not fix it. A player who hooks may need One Length’s flatter lie in short irons to help fade, but the offset is lower — that could make hooks worse.
Stop and escalate when you have hit both builds on a monitor and still see inconsistent strike patterns (toe or heel, thin or fat) after 20 balls total, or if your 6‑iron to 8‑iron gap is consistently above 15 yards. At that point, book a full fitting session. A fitter can adjust length, lie, shaft flex, and swing weight — do not try to bend lie angles yourself or order a set hoping it will work.
Key Takeaways
- Strong lofts across the set. The Standard 4‑iron at 18.5° matches many dedicated driving irons. If you need a higher launch, ask your fitter to bend a club 1° weak.
- Three core technologies. The hollow‑body construction, PWR‑Bridge (low‑forward mass for speed), and H.O.T. face insert (variable‑thickness for better ball speed retention) work together to improve distance and forgiveness.
- One Length simplifies setup. Every club matches the 7‑iron length (37.25″) and a lie near 63.5°. This removes variable‑length adjustments but may require custom lie bending for golfers with an atypical swing plane. Standard offers traditional progressive length for natural gapping and turf interaction.
- Swing weight progresses in Standard. Long and mid irons (4i through 9i) are D1. The PW and GW shift to D2. The SW is D3. This maintains feel as clubheads get shorter and heavier.
- No sand wedge in One Length. The One Length set ends at the GW (47.5°). To add a sand wedge, you will need to purchase a separate wedge or have the GW bent to a higher loft.
FAQ
What are the lofts for the Cobra Darkspeed irons?
Standard lofts are 4i 18.5°, 5i 21°, 6i 24°, 7i 27°, 8i 31.5°, 9i 36.5°, PW 42°, GW 47.5°, SW 54°. One Length lofts are 4i 19°, 5i 21°, 6i 24°, 7i 27°, 8i 31.5°, 9i 36.5°, PW 42°, GW 47.5°.
Is there a gap wedge available?
Yes, both Standard and One Length include a gap wedge at 47.5°.
What length is the 7‑iron?
The Standard 7‑iron is 37.25″. The One Length 7‑iron is also 37.25″, which is the same length for every club in that set.
What swing weight does the Darkspeed Standard set have?
The 4i through 9i are D1. The PW and GW are D2. The SW is D3.
Can I adjust the lie angles?
Yes, the heads are forged and can be bent by a qualified club fitter. Confirm with your local shop whether the One Length model can be adjusted, since hosel construction may differ.
Who should choose One Length over Standard?
One Length works best for golfers who want one consistent setup and swing plane for every iron. Standard suits players who prefer progressive length for distance gapping and varied turf interaction. Test both to see which produces more consistent strikes.
