Whether you are performing a transmission replacement or a complete drivetrain overhaul, this Double-Ended Studs for Transmissions kit delivers the reliability and precision required for heavy-duty applications. This Double-Ended Studs for Transmissions set includes all necessary fasteners for a complete and professional installation.
This double-ended stud is the primary locating and clamping element in the Double-Ended Studs for Transmissions kit. With a thread length of 65mm on each end and a center plain shank, it provides precise alignment of the transmission to the engine. The rolled threads offer superior fatigue strength, and the zinc-nickel coating ensures corrosion protection. Each stud is marked with its grade (10.9) for easy identification.
These standard hexagon nuts are used to secure the transmission casing to the studs. In the Double-Ended Studs for Transmissions assembly, each nut features a fine pitch thread (M10x1.25) and a height of 8mm. They are manufactured from grade 10 steel and include a nylon locking patch to prevent loosening due to vibration, ensuring the transmission remains firmly attached under all operating conditions.
This innovative washer is a critical component of the Double-Ended Studs for Transmissions kit. It features an internal serrated edge that bites into the mating surface, providing a positive mechanical lock against rotation. The outer flange distributes load evenly, and the spring steel construction maintains constant tension, preventing nut back-off even in the presence of severe driveline vibrations. The washer is zinc-plated for durability.
The Double-Ended Studs for Transmissions are forged from chromium-molybdenum steel and heat-treated to achieve a tensile strength of 1200 MPa. This ensures that the studs can withstand the high shear and tensile forces encountered during gear shifts and torque transfer, providing a durable and reliable connection between the engine and transmission.
The combination of embedded locking washers and nylon-patched nuts in this Double-Ended Studs for Transmissions kit provides a dual-action locking system that resists loosening due to vibration. This ensures that the transmission remains securely attached, reducing the risk of misalignment and premature wear.
This Double-Ended Studs for Transmissions kit includes exactly 12 studs, 12 nuts, and 12 locking washers – the precise quantity required for a standard C7H transmission installation. The pre-measured set eliminates guesswork and ensures you have all the necessary fasteners for a single job.
All components of the Double-Ended Studs for Transmissions are manufactured to the exact OEM dimensions and thread tolerances. The zinc-nickel coating provides superior corrosion resistance, protecting the fasteners from moisture, road salts, and transmission fluid, ensuring a long service life.
