A fork is quick; a press keeps the boot alive · review
Three separators with every dimension published — jaw opening, clamping range, drive size and thread pitch for each of the three.
The last word The most completely specified set in the hub. Three sizes, every dimension published.
Three press-type separators with published jaw openings of 22–18, 19.5 and 19 mm (0.75 in), clamping ranges to 55 and 50 mm (1.97 in), drive sizes and thread pitches.
Every figure that decides fit is published for each of the three tools. On a family where the most common failure is buying the wrong size, that is the specification that matters.
One of the three adjusts steplessly between 20 and 50 mm (1.97 in) rather than locking into positions. On an arm of an awkward thickness, that is what makes the difference between fitting and not.
Material and hardening. Elsewhere in this hub, forged and oil-hardened Cr-V is stated; here it is not.
Listed but with no offer on the American Amazon store — the reference exists there and nobody is currently selling it.

It sets how much force one turn produces and how smoothly the tool advances. A fine thread — M16 × 1.5 here — gives more mechanical advantage and finer control, which is what you want against a stubborn taper.
How far the jaws reach past the joint. Too shallow and the tool sits on the boot instead of on the arm, which is one of the ways separators slip.

Someone working on several cars who wants coverage and published dimensions.
Specifications: the manufacturer sheet for garage tools and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
20–22 mm (0.79 to 0.87 in) jaw opening · clamping range lockable at 30 and 55 mm (2.17 in) · forged · 1210 g (42.7 oz) stated
A single forged separator with its jaw opening, clamping positions and weight all published — the sort of specification a trade catalog provides and a marketplace listing does not.
Best for: A known job on a known car, where the size has already been measured.
≈ $85
18 mm (0.71 in) and 20 mm (0.79 in) separators · protective adapter for aluminum parts · forged Cr-V, oil-hardened stated
Two press-type separators in 18 and 20 mm (0.79 in), with a protective adapter for aluminum components — the detail that separates a tool from a hammer.
Best for: A single suspension job on a car whose joints are 18 or 20 mm (0.79 in).
10 pieces · C-frame press · installation and removal adapters · stated for 1/2 and 3/4 ton 4WD with Dana 44 front axle
A C-frame press rather than a separator: it removes and refits ball joints in the arm, which is a different job from splitting a taper.
Best for: Replacing pressed-in ball joints rather than separating them.
