Nitto Crank Collar - Nissan RB25DET / RB26DETT / RB30 - Skyline / Skyline GT-R (R31–R34) / Stagea (WC34) / Commodore (VL)
An extended crank collar machined from high-tensile 709 steel to drive the oil pump on Nissan RB engines. The longer drive surface gives the pump gear more to grip, which helps prevent the pump failures linked to early short-snout RB26 cranks. It is a low-cost reliability upgrade for any built RB.
Choose the drive to match your pump. The Flat Drive collar is needed for early R32 GT-R, all GTS-T and RB30 engines. The Sine Drive collar is required for every Nitto Sine Drive pump and only works with Nitto Sine Drive pumps. Sine Drive instructions: Sine Drive collar note (PDF).
Note: Installation by a professional is recommended. Engine internals must be measured and set up by a qualified engine builder.
Features
- Machined from high-tensile 709 steel
- Longer drive surface for the oil pump inner gear
- Drive edges resist wear under high load
- Locked to the crank with M6 grub screws
- Sine Drive collar has pilot holes machined for the grub screws
- Each collar hand checked by a Nitto technician
