Connecting Rods with L19 ZRP Bolts for Fiat Uno / Punto 1.6L Tempra

I-beam connecting rods for Fiat 1.4L and 1.6L Turbo engines are manufactured from high-strength 4340 steel and designed to offer high performance, extreme durability and additional rigidity. The bushings, made of aluminum-silicon/bronze alloy, feature a radial groove for the oil reservoir. They are shot peened to relieve internal stresses and undergo multi-stage heat treatment to increase their rigidity. Strict manufacturing process tolerances ensure a perfect fit and optimize oil clearance. Bending and torsion are strictly controlled. Each connecting rod includes ARP 2000 head screws with a strength of 220,000 psi. Optionally, ARP L19 material of 260,000 psi can be chosen as an upgrade. The complete kit includes ARP molybdenum lubricant and full assembly instructions. Application: Fiat Uno 1.4L Turbo / Fiat Punto 1.4L Turbo / 1.6L Tempra / 1.6L Ritmo
