Forged 4cyl
Recently Bought the Manley Forged H Beams for my Miata block. Had them professionally installed and my tech was amazed at the quality of the product. Block had to be modified for clearance but he was happy and I will see how happy I am once the motor is fully assembled!

best bang for the buck
These Manley rods are perfect. They are a very well made forged rod, they have a nice finish to them with the exception of a couple sharp edges. Which can be easily sanded smooth by hand. They are perfectly balanced with the big and little end weights of each rod written on the individual boxes. The little ends were all within 0.1 grams and the big ends all within 0.6 grams. I prefer the balance my rotating assembly within 0.5 grams but these rods are so close its not even worth the time, I'll just throw the heavier piston/ring/wrist pin assembly on the lightest rod and call it a day. The brass bushings on the little ends are All burr free and perfectly polished. All in all these rods are perfect.

Can't go wrong with these forged rods!
If you want to feel safe when making more than 260hp at the rear wheels, I highly recommend you to get this Manley H-beam forged rods.
I bought Manley H-beam forged rods at Fab9Tuning because of three reasons: quality of the product, best price, and great customer service.
I would buy these again. -
Best quality for the money.
I was very impressed with these rods. Each one comes in its own box with exact bore diameter marked on the box. Very well packaged and manufactured. Compared to other brands like Eagle, quality is very close. Cost is amazing. They even use ARP 2000 bolts. Time will tell as far as longevity is concerned, i plan on putting these to the test.
