Any extractor will wobble with an uneven load — no two frames of honey weigh the same, and trying to balance them perfectly before every spin is a losing battle. The Spring Feet Kit absorbs that imbalance at the leg level, letting you ramp to full speed almost immediately without the machine walking across the floor or needing to be bolted down. Most beekeepers who add them report they should have done it years ago. Three sizes to fit the full HillCo extractor lineup. Fits any extractor with a single 5/16" bolt hole in the leg foot — not just HillCo machines.

Run at full RPM without holding the machine or bolting it to the floor. Faster Extraction — Reaching full speed means more honey out of each frame per spin. Less time per load. Bolts On in Minutes — Replace your existing leg bolts with the spring assembly. No tools beyond what you have. Fits Most Extractors — Any extractor with a 5/16" bolt hole in the leg foot. Not HillCo-exclusive. Set of 3 or Set of 4 — Most extractors have 3 legs. Some have 4. Check your leg count before ordering.
