Price is good, but the rods need to be de-burred before installation. Balance was also off, but that's what you get with the budget brand.

I got the 5.7" rods which were within a gram with 0.002" clearance. The casting and machine work is very good. The cap screws are very strong & seemed to take the 63 ft/lbs torque no problem. The bushing to positively locate cap is a nice feature.

Cheap rods
