Almost exactly what I needed
The dog bones were slim enough to fit between the frame and rocker box. For one of the bolts I needed a longer tool. Would like to see a set that is 2 inches longer and includes a 1/2" bolt size as well. Overall well made, nice finish, strong, and almost exactly what I needed!

Torque wrenches
Really make your job much nicer and easier. Wish I had this item years ago.

Torque value
I suggest if using this adapter for your head bolts, you tighten all the head bolts with it, as it adds length to the torque wrench. The final torque values will be different if only used on 1 or 2 and not all. This is a good and needed tool for that one hard to reach bolt, just use the tool on all bolts for uniform torque tightness.

As advertised
Works like a champ.

Dog bone wrenches
Overall they worked fine and are of excellent quality. I wish they had more sizes like 1/2 and 3/8 inches.

Worth there weight in gold
Get em. Can't tighten head bolts without em.

Top notch pcs.
Positive, These work as well if not better than Snap On pcs. that I machined to clear fins.

Exactly What Is Needed
This is exactly what is needed to work on the barrels and heads of a shovelhead. Wish I would have had them 20 years ago....Thanks

Dogbones
Havent used them yet but they look and feel solid and are good quality product. They are a valuable addition to my toolbox.

Great Tools
Purchased and used to help torque down engine mount bolts. At first glance, they seem a little on the thin side but they are solid. I believe that’s purposefully done so that they fit in small areas. Great product, glad to have them in my tool arsenal and looking forward to using them in the future!


shovelhead base nuts needed torque'n
Awesome quality.

Torque wrench dogbone adapters did the trick!
Great product! Helped get that tricky Shovelhead rear cylinder head bolt to the correct torque. Very impressive product. Prevents having to chase down a Snap On or Matco truck to find an accessory to do the head bolt job. Highly recommend putting a set in the toolbox.

Looks like quality product
Worked great., Quality piece

Shovelhead
Have not used them yet. Quality made. Fit correctly with clearance to the cylinder. No more Snap-on s wrench. When needed I can now correctly torque the heads and cylinder. Another good Lowbrow product!

Panhead Big Bore -> Partial Score
Pan and Shovel cylinder and head bolts have always had access and clearance issues. My S&S retro-pan engine with 3-5/8" big bore cylinders makes clearance even worse than stock. I have a nice set of Carlyle torque adapters which are a tiny bit too big (I'll grind them down as a last resort). Always on the lookout for good tools, this set looked promising and made in OH/USA so I got one. Quality looks good, appears to be hardened tool steel and precision cut. Haven't used yet, only test fit so can't comment on durability. 7/16" wrench size fit nicely on 12pt head bolts. But, cylinder base nuts on this engine require 1/2" 12pt wrench which is NOT included. Since I bought these specifically for this application that is my reason for 4-star review instead of 5. Manufacturer should consider offering a complete 9pc 3/8 drive set (~$129) plus singles for those who only want 1 or 2 sizes.
