SZM JACK BOLT KIT (SET OF 2) NISSAN GTR R35

The Nissan GT-R R35’s GR6 dual-clutch transmission utilizes a high-interference fit between the transmission casing and internal components that often makes disassembly for maintenance or upgrades difficult without specialized tools. During high-load operation or after numerous thermal cycles, the casing halves and internal structures can become "cold-welded" or seized, leading to the mechanical problem of casing deformation or gouging when forced apart with makeshift prying tools. The SZM Jack Bolt Kit is engineered to solve this extraction challenge by providing a high-precision mechanical advantage that applies uniform separation force, ensuring the integrity of the transmission’s mating surfaces is maintained during critical service intervals.

Constructed from validated Grade 12.9 high-tensile steel, these bolts are designed to handle the significant torque required to break the seal of factory RTV and press-fit tolerances. The high-precision thread pitch is specifically matched to the GR6 transmission’s service ports, addressing the risk of thread stripping common with lower-grade hardware. By utilizing these bolts, professional tuners can ensure a controlled, parallel separation of the transmission components, which is a validated requirement for protecting the delicate internal sensors and oil-sealing galleries from impact damage during the teardown process.
