Cobra OPTM Driver, Fairway, & Hybrid Weight

This replacement weight is compatible across the full Cobra OPTM metalwood family, including the LS, X, Max-K, and Max-D drivers, the LS Titanium, X, and Max fairway woods, and the OPTM hybrid. That makes it one of the few aftermarket options covering all three club types in the OPTM lineup, which is especially useful for golfers building or re-shafting a matched set. If you're unsure which model you have, check the sole of the clubhead for the OPTM designation.

With options spanning from 3g to 15g, you have roughly 12 grams of adjustment range, which translates to approximately 6 swing weight points from lightest to heaviest. That's a wider tuning window than most aftermarket weight systems offer, giving fitters and builders meaningful flexibility when compensating for shaft weight, playing length, or personal feel preference. For reference, most standard driver builds target a swing weight between D0 and D5, and this range comfortably covers that entire spectrum.

Yes, the factory Cobra OPTM weight system uses both a screw and a washer to secure the weight in the sole port, and skipping the washer can result in an improper fit or unwanted movement during play. Each weight in this listing ships with the screw and washer included, so you have everything needed for a clean, factory-style installation right out of the box. No need to source hardware separately.

Each order quantity of 1 includes one (1) individual weight in your selected gram option. Multiple weights and color variations may appear in our listing photos to showcase the available options, demonstrate installation, or provide product context — but a single quantity at checkout means one weight will be shipped.

If you need multiple weights, simply adjust your quantity at checkout or add each gram option individually to your cart.

Due to standard manufacturing tolerances, the exact weight of each component may vary slightly from the listed gram value. Our target tolerance is ±0.5 grams, and in practice our components frequently exceed that standard — meaning real-world variance is often even tighter than our published tolerance.

For context, golf club heads from major manufacturers typically carry a tolerance of ±1–2 grams, and golf grips and shafts often have similar or larger variances. Our ±0.5g target is held to a higher standard than most of the components already in your bag. For products that include a screw and/or washer, listed weights reflect the total weight of the component including the screw and/or washer that ship with the product as an "installed unit weight."

These minor variations do not significantly impact performance and are well within accepted industry standards. Please review these tolerances before purchasing. By placing an order you acknowledge these variations as a normal part of precision manufacturing. If you have any questions before ordering, feel free to contact us.
