So I received my set of three Capris last week and took them apart and lubed them and looked at the mechanism. The internal design is closest to the Tekton, and this is the best design IMO because the gear uses a cylindrical pilot on the rear to locate it into a machined recess in the ratchet body- Tekton is the same. The gear in the Gearwrench is just floating around in the case and basically located by the cover plate and the ID of the machined recess to OD of the gear. Matco is similar but a step above the GW in that the cover plate sits on a machined step in the body where the GW cover plate sits on the gear itself. Saying that, I don't think this really matters overall, and it doesn't matter in strength, but positively locating the gear on both ends, and having the cover plate sit on a step, and not directly on the gear, is the "correct" way to do it from a design standpoint. Again, it doesn't matter, but there's almost zero slop in the Capri gear/anvil in comparison to the GW, Matco, and Snap On 88 (I only have SO 1/4" at 72T). Tekton is second behind Capri as far as slop. Also, the Capri gears are different from Tekton, and of course Matco and GW. The Capri gears are taller than Tekton, GW, Matco, and this is only counting the toothed portion. Of course, the diameters mostly also vary, and I don't think it matters, but the Capri shouldn't be weaker as long as they're similar material and heat treat since the anvil typically breaks first.
Overall, I really like these. I'm looking forward to some expanded offerings.
Oh, the Capri heads are thicker than GW, Matco, and Tekton. To go along with this, the handle diameters are larger to match the thicker heads. I actually geeked out and made a bit of a dimensional and comparison table so maybe I'll start a comparo thread.
