ARP L19 and ZRP Connecting rods join forces to provide ultimate durability and reliability to every car enthusiast seeks for the best.
As everybody knows, ARP Pro series connecting rod bolts are precision CNC-machined to exacting specifications and designed for optimum reliability. They are heat-treated and threads are rolled to provide up to ten times more fatigue strength. This makes them far superior to standard OEM fasteners in terms of durability, and fully capable of handling the extra stress of high-combustion engines.However, the time for a costless upgrade has come.
|The ARP L19 is used as standard, for its additional strength and reliability that they offer.
||This is vacuum melted alloyed steel with sufficient chromium and carbon to achieve high hardness It is a proprietary material capable of achieving an impressive clamping force of 260.000/270.000 psi as may be required.
|This setup is capable of 800Hp in four cylinder engines and 1000+ in six cylinders. Although they are fractionally more expensive, we feel that they accompany our rods very well so we have not increased the price of the set. This translates to the best value for money rods in the market!
For extreme applications, ZRP offers as an option even higher rate bolts, the latest Custom Age 625 plus bolts (CA625+).
These bolts (CA625+) are made of a newly formulated alloy that demonstrates superior fatigue cycle life, tensile strength and toughness with complete resistance to atmospheric corrosion and oxidation. Typical tensile strength range is 260.000 to 280.000 psi. These bolts along with ZRP rods make a bulletproof combination, capable of more than 1000Hp!
