Make piston work easier with Powerhouse compound angle piston vises. These vises possess a unique compound angle feature; it rotates the piston not only from front to back but also from side to side--a definite must for Ford and big block Chevy pistons! Made from aluminum and blue anodized Powerhouse piston vises locate and hold the pistons by two wrist pins. And they're repeatable which means that once you set up the vises you're ready to drop in the other pistons and go--even upside-down--for balancing or lightening operations. Let Powerhouse Products compound angle piston vises help you with your automotive rebuilds.
