Yes, 8 counterweights. 

A Gen I small-block casting has a measurement of 19.25-inches between from front main cap to rear cap, while the LS Next has 17.50-inches at the same dimension, a difference of 1.75-inch.  That’s where Dart's fully-counter-weighted billet crankshaft comes in.  With 8 instead of 6 counter-weights, the crank is substantially stiffened.  This reduces flexing and thereby puts less stress on the mains.  

The cranks we use have a 4.000 inch stroke with a standard LS1-type snout.  3.622 inch stroke and long snout LS7 versions are also available as special orders.

Our Part# BRE007736 features:
- 8 counterweights.
- Long and short snouts available.
- Heavy duty rod cheeks.
- Small hole through the rod pin.
- Rough balanced @ 1780 grams.
- No mallory required.
- 4340 Billet.
- 4.000” stroke.

As usual, BOROWSKI RACE ENGINES was in the front of the line when Dart introduced this product.  We put the first one in 427ci LS3 Whipple supercharged build for a GMC Syclone that went on to be feature vehicle for BRE and Dart at Holley's LS Fest in 2016.  They have been in a lot of our builds since then.

Call us at 815-725-2727 if you have any questions. We can of course build a complete engine around it if you are so inclined, or just sell you the crank.
