Dial in your perfect spine with tradition, precision, and power.
Iron Oak Carbon Shafting Test Kits are designed for the serious traditional archer looking to fine-tune their setup for maximum performance. Each kit includes multiple spine options, giving you the chance to test and identify the ideal match for your bow and shooting style.
Built for strength, accuracy, and consistency, Iron Oak shafts feature a slim .204" inside diameter that delivers deeper penetration, reduced wind drift, and a tighter center shot—all critical for precise tuning and superior performance in the field or on the range.
These shafts combine modern carbon durability with a classic wood grain finish, paying homage to the heritage of traditional archery. The smaller diameter enhances long-range accuracy and offers a flatter trajectory, making them a top choice for traditional bowhunters.
Whether you're paper tuning, bare shaft testing, or just chasing tighter groups, the Iron Oak Carbon Shafting Test Kit helps you find the spine that hits the mark.
Available in three different test kits with four spines in each kit:
