Standard, Heavy Duty or Pro Series?
READ MoreSTANDARD SERIES
More economically priced but without compromising quality and performance. The shape is optimized depending on the model, some come in an H-Beam shape and others in I-beam shape. Depending on the application and if it is turbo or N/A use the design is customized for weight and rigidity.
HEAVY DUTY SERIES
Built from the finest raw materials with a specially optimized shape which also accommodates a 3/8th bolt in all applications. The design of these rods has been developed, based on our experience, to each application individually in order to optimize the design depending on each engines character.
The new Heavy-Duty series conrods from ZRP easily fulfill the highest standards of Motorsport.
PRO SERIES 817M40T – EN24T ALLOY
In our continual quest for improvement, we proudly introduce an all new series of ZRP conrods, aimed for the Extreme applications.
Built from the finest raw materials with a specially optimized shape which also accommodates a 3/8” L19 cap fasteners in all applications.
For those that are not familiar with this, let us say that it is a high tensile alloy steel, renowned for its wear resistance properties. 817M40T steel is a popular grade of through-hardening alloy steel due to its excellent machinability in the “T” condition, the hardness is in the range 248/302 HB. 817M40T – EN24T can be further surface-hardened to create components with enhanced wear resistance by induction or nitriding processing. These qualities make it the finest material you can use for Conrods manufacturing, where high strength properties are required.
ZRP Connecting Rods Features
• AMPCO 18 bushings for excellent resistance to wear and fatigue • Bushings include radial groove for oil reservoir • Shot Peening for improved fatigue life • Magnaflux Inspection guarantees the consistency of the forged material meets our high-quality standard • Multi Stage Heat Treatment for maximum strength, dimensional stability, and fatigue life • CNC machining for superior tolerances as tight as 0.0002″ • Center to center is a maintained to .001″ tolerance • Finite Element Analysis FEA Computer generated stress analysis of con rods • Bend and twist is tightly controlled • Optimal balancing for weight matched sets ± 1gram
No matter what your racing field is, drag, drift, or time attack, ZRP‘s new series of connecting rods will keep your engine revving!
SUPERSPORT OR DIAMOND SERIES?
READ MoreSUPERSPORT SERIES
As the name suggests, these will be developed for mild to high tuning mainly for road or race cars that want to develop their engine for high mileage and/or street use. These will be designed by ZRP engineers and manufactured in Germany from 4032 (T6) high-silicon alloy, low-expansion alloy which allows the engine builder to run a closer piston to bore tolerance thus producing a better seal. This helps remove the slapping noise during cold start, common place among engines running forged pistons due to larger then OE bore clearances. We have chosen Round Style Skirt design for Turbo Application and X-Style skirt for Natural aspirated engines with Over size and deeper valve pockets to allow even the most extreme camshaft profiles to be used. They have Offset pins for quiet operation and the wrist pins are made from 9310 alloy. Other features include Anti-detonation grooves to protect the first rings, gas pressure accumulator groove for better ring seal and vibration relieve. Premium Japanese quality 1.00mm x 1.20mm x 2.80mm ring package included.
Optional coatings available per request:
Thermal barrier coating “Blast Off Bronze” / Moly Side-Skirt and Under-Crown coating “Stealth Black”
DIAMOND SERIES
The high-performance pistons series will be called “Diamond Series” and they will be engineered with only one thing in mind: WINNIG RACES. These will be manufactured from Diamond Racing in the USA from 2618 material. Diamond racing company is known from the late 60s to produce the highest quality engine parts around. The past 2 decades Diamond has solely dedicated itself to manufacturing forged pistons. With all state of the art machinery they offer customers the state of the industry in machining. The Coordinate Measuring Machine (CMM) is one of several sophisticated pieces of measuring and modeling apparatus used in Diamond’s engineering department. The CMM provides very accurate measurements, measuring the location and details of valve pockets, for example, to within a .0001in. This laser scanner is used for modeling purposes, especially for scanning piston domes where it scans thousands of surface points in minutes. Developing the highest quality pistons in the industry by using the latest CNC machinery and computer software aids, as well as providing unmatched quality control. With these credentials it was only a matter of time before we decide that this is the firm to work with for making unlimited horsepower!
Optional coatings offered per request:
Thermal barrier coating “Blast Off Bronze” / Moly Side-Skirt and Under-Crown coating “Stealth Black” / Hard anodized coating / Double diamond coating / PTFE coating, Hard anodized and Teflon seal coating
