ISR Performance Driveshaft - RB20 Swap S13 ABS - Steel

Our one-piece steel driveshaft for the S13 240SX RB20DET swap running the factory RB20DET 5-speed transmission and an ABS-style differential. Steel construction for builds where ultimate strength matters more than shaving rotational mass.

What It Does

Replaces the factory 2-piece driveshaft with an ISR one-piece steel shaft. Eliminating the rubber carrier bearing in the middle gets rid of the vague feel under acceleration that's baked into the stock 2-piece design. Steel offers more outright strength than aluminum, which is the call for builds making big power and seeing real abuse. Built using Dana and Spicer solid high-performance u-joints for serious durability.

Fitment

Fits the Nissan 240SX S13 chassis with the following swap configuration:

• Nissan RB20DET engine
• Factory RB20DET 5-speed transmission (RB-native, no adapter plate required)
• ABS-style differential
• ISR Performance swap mounts and swap components throughout

Critical: Driveshaft length is determined by your differential, not by whether your car came with ABS from the factory. Some S-chassis owners swap in non-ABS diffs (or vice versa); confirm which differential is actually in your car before ordering. This shaft is only guaranteed to fit when using ISR Performance swap components.

Lead Time

Built to order. Approximately 1 week lead time.
