Stud bolts, connecting rod bolts for professional tuning from PRO SERIES

For us, everything has always revolved around the optimisation of engines, completely independent of the manufacturer. From A as in Audi to P as in Porsche to V as in Volkswagen - at PRO SERIES you will find high-quality stud bolts, connecting rod screws and other connecting elements for a wide range of manufacturers and models. Sure, such delicate components as nuts, bolts or washers usually get little attention. Nevertheless, they perform absolutely heavy-duty work, holding the engine or crankshaft together in the truest sense of the word. PRO SERIES' hour has come where standard materials fatigue most quickly. Our connecting elements such as high-strength stud bolts, connecting rod bolts and screws withstand the highest loads and convince through precision-fit production, high-quality materials and a high degree of functionality and durability.

Development and production of stud bolts and connecting rod screws at the highest level

PRO SERIES can look back on a long history of success in the development, production and distribution of stud bolts, pins and connecting rod bolts. With passion and a lot of heart and soul as well as with an eye for the essentials, we work on being able to offer vehicle-specific components for all common manufacturers. Regardless of whether you have discovered your passion for Mercedes or a Opel, whether you drive Toyota or Mazda - we are at your side and offer you fixed connecting elements for a multitude of commercially available engines. As experienced developers and specialists in the field of engine optimisation, no challenge is too big for us: That's why we can also produce special designs according to your specifications, which are not available a second time. Try out this special service and let us advise you!

Success through quality and know-how

Our success is no coincidence: We at PRO SERIES not only have the most modern machines, up-to-date technology and precise tools, we are also always close to the action and implement the latest standards. Our developers and mechanics impress with their experience, know-how and passion for the profession, which we at PRO SERIES regard as a vocation. And so it is that we not only have high standards for ourselves, but also for the material we use. We only use raw materials whose origin we have carefully checked, and we provide our connecting rod screws, stud bolts and washers with special alloys that enable outstanding corrosion protection. High tensile strength and rolled threads ensure that our bolts cope with any load with flying colours. Whether Nissan, Seat or Skoda - at PRO SERIES you will find what you need!

Professional advice and fast delivery

At PRO SERIES, we stand for quality and competence; of course, this doesn't stop at order processing. We also work precisely and efficiently in the warehouse and logistics in order to process your order - for example a stud kit for your Mitsubishi or a custom-made product for your Lamborghini - as quickly as possible and to your complete satisfaction and to get your studs, bolts or other connecting elements on their way. Customer service is more than just an empty phrase for us. That's why we respond individually to our customers and are there to help and advise. You have a question about our stud bolts for your Subaru? You drive a Chrysler and are looking for suitable connecting rod bolts that you have not been able to find anywhere? This is a case for PRO SERIES! We will take care of your enquiry and will be happy to advise you!
