ISR Performance Driveshaft - LS T56 Swap S14 ABS - Aluminum

The ISR Performance One-Piece Driveshaft is built for LS swaps into the 1995-1998 Nissan 240SX (S14) using the F-body T56 6-speed transmission and the ISR LS swap kit. Built from aluminum with Dana/Spicer solid high-performance u-joints. This is the ABS-equipped differential version.

What It Does

LS-swapped 240SX builds need a custom driveshaft because the LS engine and F-body T56 transmission combination, mounted on ISR's swap mounts, positions the transmission output flange differently than the factory KA/SR setup. This driveshaft is built to the exact length that combination requires, with the correct flange pattern on the diff side. Like all ISR one-piece shafts, it eliminates the factory two-piece carrier bearing for a more direct driveline.

Aluminum construction reduces rotating mass compared to a steel shaft, which translates to slightly quicker throttle response and lower driveline inertia. Common pick for built LS swaps and serious track or drift builds where every bit of rotating weight savings matters.

Critical Fitment Requirements

F-body T56 only. This driveshaft will NOT fit the T56 Magnum transmission. The T56 Magnum (aftermarket Tremec unit) has different output flange geometry and a different overall length than the original F-body T56. If you're running a T56 Magnum, contact ISR or a custom driveshaft shop for the correct part.

Only guaranteed with the complete ISR Performance LS swap kit, including ISR swap mounts. If you're using a different brand of swap mounts, custom mounts, or a different transmission mount configuration, fitment cannot be guaranteed.

Differential type matters. Driveshaft length is determined by your differential, not by whether your car originally came with ABS. Verify which differential is currently in the car (ABS vs non-ABS) and order accordingly. The wrong diff-side driveshaft will not bolt up.

Fitment

• 1995-1998 Nissan 240SX (S14)
• GM LS engine swap
• F-body T56 6-speed transmission ONLY (Camaro/Firebird/Trans Am/Pontiac GTO T56)
• NOT compatible with T56 Magnum
• ISR Performance LS swap mounts (required)
• ABS rear differential (verify your current diff, not the car's original ABS equipment)

Lead Time

Built to order. Approximately 1-week lead time before shipping.
