This is a slap ramp specifically for the StingRay 4. It's a more seamless ramp, based on the Ver7 type. Additionally, the fingerboard has been extended and rounded to a moderate degree for thumb landing. There may be slight differences depending on the year, so we will design it to be adjusted to match your specific model. We also create the special-shaped finger ramp shown in images 3-5. If you would like to purchase a set, please contact us. We will offer a discount. Sterling and SUB models have slightly different end shapes, so please consult with us separately if you own one of these.
