MR-RTCA-NS14Nissan 240SX Rear Lower Toe Arms

These arms allow you to change the static toe and toe change during suspension compression and load. An easy bolt-in upgrade, alignment is required after this install.

MR-RUCA-NS14 – Nissan 240SX Rear Upper Control Arms

These arms are meant to adjust rear camber to whatever specifications you desire. Replacing the stock rubber bushings with pillow ball ends provides a upgrade in stiffness and response.

Here is the car in question before the install :

Tools you will need for this install :

  • 14mm socket and open ended wrench
  • 17mm socket and open ended wrench
  • 19mm socket and open ended wrench
  • jack and jack stands
  • MR-RTCA-NS14 – Nissan 240SX Rear Lower Toe Arms
  • MR-RUCA-NS14 – Nissan 240SX Rear Upper Control Arms
First jack up the car and secure it safely using your jackstands, for those of you fortunate enough to work on a 2 post lift, just remove your wheels.
First use your 19mm socket and open ended wrench to undo the outmost bolt holding your rear upper control arm in place.

Next take off the rear bolt, and put the bolts safely away. You should now be able to remove your entire rear upper arm

Now, you’re ready to install your rear upper arm but not before lining your old arm up and adjusting the Megan arm to a similar length. You will need an alignment after this install regardless, so you might want to keep the jam nuts loose.

Next undo the outer most bolt in your rear lower toe arm, this bolt is located to the rear and left of your shock housing ( from the driver side )

Now, undo the inner bolt and this arm will come right off

Now install your new rear toe arm by reversing the process and you’re done!

Make sure your jam nuts are tight if you cannot align your vehicle right away, you don’t want them coming loose on you.

After your alignment, you should be ready to rock and roll!

Happy Drifting!
