AMGO Turnplate Adjustment Blocks, Kit No. 40905 This is a part that only makes sense in company. It is an optional set of adjustment blocks for an AMGO alignment four-post lift, and it is used together with the turnplate kits — 40903, 41203 and 41403 — rather than on its own. If you have arrived here trying to work out whether you need it, the honest first answer is that it depends on which turnplate kit you are running and which lift it is going on. So this page does two things: it explains what the blocks are for in an alignment setup, and it tells you exactly what to confirm before ordering. It does not invent dimensions we do not have. Where the blocks sit in an alignment setup An alignment four-post is three separate things working together. There is the lift, which puts the vehicle at a workable height and holds it level. There is the turnplate arrangement, which frees the steered wheels so the suspension settles honestly. And there is the hardware that makes the second sit correctly in the first. That third part is where these blocks live. In an alignment bay the relationship between the plate and the surface the wheels roll on is not a detail — it is the setup. A plate that does not sit as intended within the runway changes what the vehicle is standing on, and anything that changes what the vehicle is standing on is capable of changing what the gauges read. Getting that relationship right is not glamorous work; it is the work that decides whether the rest of the equipment can do its job. Why this is sold separately The obvious question is why an alignment lift does not simply arrive with everything it needs. The answer is that "an alignment four-post" is not one configuration. The lift can be specified with different turnplate kits, and the models in this family — the PRO series — are not identical to one another. Selling the blocks as an optional item keeps the combinations honest: you order the parts your configuration needs instead of paying for a bundle that assumes a setup you do not have. The cost of that flexibility is that the buyer has to know their own configuration. Hence the checklist below, which is genuinely the most useful thing on this page. Confirm these three things before you order Your lift model. The current listing gives the applicable models as PRO-12ASX, PRO-12A, PRO-14A and PRO-14AE. The product's own title gives a shorter list. Those two do not agree, and rather than pick one for you we will check your exact model against the manufacturer's parts documentation — read the code off the lift's data plate and send it to us. Your turnplate kit number. These blocks are used with kits 40903, 41203 and 41403. Which of those you have is a fact about your lift as it was supplied, not something to assume. What you are actually trying to fix. If you are setting up a new alignment bay, this is a build-list question. If you are solving a problem on an existing lift, tell us what the lift is doing — the answer may be these blocks, and it may be something else entirely. Perfect For Alignment bays being commissioned, where the turnplate installation is being specified properly rather than improvised. Shops adding a turnplate kit to an alignment four-post that did not previously carry one. Multi-bay operations standardising several lifts on the same setup so any technician can walk into any bay. Owners of PRO-series alignment lifts replacing hardware that has been damaged, lost or improvised over the years. What is in the box Supplied as one set under kit number 40905. We do not publish a piece count, block dimensions or an adjustment range for this item, and we are not going to estimate any of them — for a part whose whole purpose is dimensional, a guessed figure is worse than none. Ask us before ordering and we will confirm the contents against the manufacturer's parts documentation for your lift. Specifications Kit number 40905 Type Optional turnplate adjustment blocks, alignment four-post lift Listed lift models PRO-12ASX, PRO-12A, PRO-14A, PRO-14AE — confirm yours with us Used with turnplate kits 40903, 41203, 41403 Sold as One set Collection Delivery or warehouse pickup Certification and compliance We publish no third-party safety listing for this accessory and none is implied here. A lift's safety listing, where one exists, describes the lift in the configuration the manufacturer tested — which is a reason to fit manufacturer hardware rather than a shop-made substitute, and a reason to ask the manufacturer directly if an inspector, an insurer or a fleet standard governs your bay. We will help you get that answer in writing before you order. Delivery and pickup Delivered within the lower 48 or collected from the warehouse, with shipping calculated against your address at checkout rather than estimated here. Check the package before signing for it: machined steel blocks are heavy for their size and a dropped carton can distort exactly the surfaces that matter. Anything you find goes on the delivery paperwork at the time — that note is what a claim rests on. Warranty Terms and the claim process are set out on our warranty claims page, and we will provide the current manufacturer document before you order if it matters to your decision. If something fails, photograph it in place and contact us before it is taken apart — a component already dismantled is generally treated as modified, and that is how a good claim turns into a bad argument.
