TRM Wiseco Pistons


SKU: 003-Piston Categories: ,


In a joint effort with Wiseco, we have developed a true 8.5:1 low-compression piston for the M5X based platforms. The pistons are available in 85mm and 87mm bore diameters. The piston is designed to be the most robust solution you can get for an ‘off-the-shelf’ piston.   Please note piston sets are custom order, expect 4-6 weeks for delivery.  Features include:

  • True 8.5:1 compression
  • Modified valve relief areas for longer piston life and durability
  • Toughened ring lands
  • Thicker pin bosses allowing for a stronger piston and better heat dissipation
  • Upgraded wrist pins
  • Pre-coated skirts
  • Designed for use with 135mm connecting rods
