Nissan S14/S15 Quick Change Weld In Mount
This kit is designed to fit Nissan 240SX S14 and S15 models (1994–2000).
It allows you to mount a Winters, Bull Dog, or Speedtek quick change differential (Speedtek requires metric hardware), giving you a ton of flexibility when it comes to gearing and setup.
Beyond just mounting the diff, this kit was built to seriously strengthen the rear subframe wherever possible (and still stay within legal limits). It’s made from high-strength material with a 210,000 psi yield strength, compared to roughly 44,000 psi for mild steel. It’s built to handle abuse.
A solid option if you’re looking to run a quick change and add strength to the car at the same time.
