ISR Performance 5 Lug Hub Conversion - Nissan 240sx 89-94 S13

The ISR Performance 5 Lug Hub Conversion Kit for the S13 240SX converts your factory 4-lug front and rear hubs to a 5x114.3 5-lug pattern. Direct hub replacement, no spindle or ball joint modification, plug-and-play installation on both front and rear. Standard Nissan 5x114.3 pattern with M12 x 1.25 studs for the widest aftermarket wheel selection.

What It Does

The factory S13 240SX uses a 4-lug hub pattern, which severely limits aftermarket wheel selection. Converting to the more common Nissan 5x114.3 pattern opens up the full range of 350Z, Skyline, and most aftermarket wheel options. Unlike many conversion kits that require spindle modification or ball joint changes, the ISR kit is a direct hub swap. Remove the factory hubs, install the 5-lug hubs, and you're done. CNC-machined hubs with integrated bearings, standard knurl spec for proper stud retention.
