The included ball caster pieces are held in place by a removable retention clip, and the whole assembly conveniently snaps onto the front/top edge of the Balboa chassis. This kit is also useful in balancing applications, where the ball caster can be left off and the extension piece can be used to make the Balboa taller and give it more mounting points. The parts for this kit are already included in the Balboa Chassis with Stability Conversion Kit. ## Pricing - **Price:** $17.75 (inc GST) — $16.14 AUD, exc GST - **Quantity discounts:** 10+ $15.49 (exc GST) · 25+ $15.01 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Aug 31 and Sep 02. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=POLOLU-3572:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/POLOLU-3572:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description The Stability Conversion Kit for Balboa consists of a chassis segment that clips onto the end of the Balboa chassis to extend it, a 1"-diameter plastic ball, three plastic rollers, and a ball caster retention clip that holds the ball and rollers in place: | \| [![](https://core-electronics.com.au/attachments/localcontent/0J8846_100625ef854.jpg)](https://core-electronics.com.au/attachments/localcontent/0J8846_23710a39597.jpg) \| \|---\| \| Stability Conversion Kit for Balboa. \| | \| [![](https://core-electronics.com.au/attachments/localcontent/0J8766_93183c084c.jpg)](https://core-electronics.com.au/attachments/localcontent/0J8766_20740a76adf.jpg) \| \|---\|---\| \| Stability Conversion Kit for Balboa. \| | \| [![](https://core-electronics.com.au/attachments/localcontent/0J8782_10724dafec3.jpg)](https://core-electronics.com.au/attachments/localcontent/0J8782_36628f56674.jpg) \| \|---\|---\| \| Stability Conversion Kit for Balboa, bottom view. \| | |---| With the ball caster included, this piece can be used to provide the Balboa chassis with a smooth third point of contact for traditional differential-drive applications.
