ZRP racing H-shafts - connecting rods for the highest loads as they occur on performance-enhanced engines. Switching to steel connecting rods is particularly advisable for turbo conversions, as well as when converting to 16VG60.
The ZRP steel connecting rods on offer are forged from 4340 steel. The connecting rods are precisely balanced to the gram. Not only the total weight, but also the rotating and oscillating masses. The surface is shot-peened. The crankshaft bore and piston pin bore are of course finish honed.
For VW 16V KR, PL and 9A engines
