ISR Performance 5 Lug Rear Conversion Hub - Nissan 240sx 89-94 **Single Hub**

Completing the rear half of an S13 five lug swap, the ISR Performance 5 lug rear conversion hub replaces the factory 4 lug rear hub on the 1989 to 1994 Nissan 240SX. It lets the rear axles bolt up to a 5 lug flange so the car can run the same 5x114.3 wheels front and rear. This listing is for one rear hub; a pair of rear hubs is also offered.

Rear hub considerations on the S13

Unlike the front, the S13 rear hub carries drive torque from the axle, so a conversion hub has to take both wheel loads and the twist of a turbocharged SR20DET. ISR's hub is machined as a direct conversion piece, so the rear knuckle, bearing arrangement and axle stub all work as they did before, just with five studs.

Specifications

• Wheel stud thread: M12 x 1.25
• Stud knurl size: 14.5mm
• Sold as an individual hub or as a pair of rear hubs

Fits

Nissan 240SX S13, 1989 to 1994, rear. Use with the ISR 5 lug front conversion hub so both axles share one bolt pattern.

Install notes

Pressing the hub into the rear bearing and torquing the axle nut to spec are the critical steps. The 14.5mm knurl matches common extended studs for spacer use. Check that rear rotors or drums are 5 lug and centered correctly before final assembly.
