SEMA 2015: It’s About The Weight For JE Pistons

JE Pistons’ BBC Open Chamber FSR pistons are one of the most advanced BBC piston available today.

It’s no secret that lowering rotating weight is a great thing for horsepower hunters when it comes to building that big-block Chevy monster for your pride and joy, however there was a gap in the JE Pistons FSR line when it came to big-block Chevrolets.

“We already had lightweight pistons in our FSR (forged side relief) line so it made sense to expand the line to include a lightweight gas ported BBC open chamber piston,” explained Jeremy Anderson. “This one is the most advanced big-block Chevy piston available.” 

JE Pistons revolutionized piston design in the last few years with its 3D undercrown milling procedure that allows the design team to reduce weight by contouring the undercrown of the piston. This allows the weight to be placed where it is needed for strength.

JE Pistons also has perfected the piston skirt designs for maximum strength.

Features Of The BBC Open Chamber Lightweight FSR GP Pistons:

  • Hollow dome FSR forging
  • Lateral gas ports
  • Wire locks
  • 3D undercrown milling
  • 990-2500-18-51C wrist pins
  • Manufactured with 2618 high strength alloy
  • Compatible with all open chamber cylinder heads

The GM LS1 engine has been so popular that JE Pistons put extra effort in expanding its LS1 series product lines to provide customers with the same forged side relief  (FSR) forgings that have been popular in other applications.

The LS1 Extreme Duty FSR piston design focuses on lightweight with extreme durability.

“Not only are these LS1 Extreme Duty FSR pistons designed to hold up to high output, but we have found ways to reduce weight and maintain the durability of these pistons for street or strip use,” said Anderson.

Features Of The LS1 Extreme Duty FSR Piston:

  • High strength FSR forging
  • Accumulator grooves
  • Double pin oilers
  • Offset wrist pin
  • Round wire locks
  • 927-2250-15-51C or 945-2250-15C wrist pins
