The rods are forged H-beam rods with ARP rod bolts. 6.243" length for use with stock 3.58 stoke crank and the pistons listed above.
The pistons
2618 forgings
Strutted skirt design with as little as .004" clearance
excellent skirt wear and minimal noise or knock
radiused valve pockets for detonation resistance and increased flow around the valves
anti-detonation grooves with the added benefit of keeping the top ring groove free of carbon
3mm oil rings for better oil control and reduced friction for more hp
pressure groove for enhanced ring seal
chrome moly pins and spiralox
tool steel pins optional
brush domes require minimal deburring by the engine builder
skirt coated for lower friction, reduced noise, and superior life
multi fit valve pockets for interchangeability of cylinder heads
Cost is $1200 for pistons, rods, wrist pins, and rings. If you want a forged 6.1 crank to go with it, add $400. We can also balance this assembly and add bearings for an additional $300.
