How to Replace Coilover Suspension on S13 Nissan 240SX

Difficulty: Moderate

Have an idea of how low you'd like the car and adjust the coilovers individually and mark them so you they will be even through all 4.

Step 1

Let's take a look at the new Blitz ZZR coilovers in comparison to the old KYB.

Note: Before getting started be sure you have all tools necessary and a clean working space.

Step 2

Before installing the new coilovers, be sure to adjust the ride height on all 4 by loosening the lower collar and spinning the chamber to the height you choose.

It is also wise to check the tightness on the coilovers before installing. Always better to be safe than sorry.

Step 3

Image 1: Jack up the car, or in this case use a lift.

Image 2: Remove wheels

Image 3: The brake cable is attached to the car by a metal clip, use a pry bar or needle nose pliers to remove the clip.

Step 4: Front Coilover Removal

Remove the two bolts from the strut to the spindle.

Loosen the top 3 nuts on the strut tower.

Once these are loosened you'll notice the coilover dropping, grab it with your hand or use a friend to help secure it so it doesn't fall.

Step 5: Removal of rear coilover:

Remove bottom nut so the bottom of the coilover is unattached.

Find the cover for the rear strut tower and loosen the 3 bolts.

Once these are loose you'll notice the coilover dropping.

Use a spare set of hands to grab the coilover and secure it while removing these nuts.

Step 6

Install the new coilovers the same way the previous ones came out.

Put the studs through the top 3 holes and tighten the nuts hand tight.

Align the bottom of the coilover up with the spindle and use some force to hold it up and align the holes.

We used a jack and a rubber mallet to hold up the spindle.

Install the brake cable clip

Step 7

Steps for installing are the same for front and rear.

Install top mount into the holes and hand tight the nuts.

Tighten bottom nut back onto knuckle.

Step 8

Install the wheels back on and enjoy you're new ride style!

Here are some pictures of the differences between the coilovers- weight wise.

3lb per coilover, not bad. Lower, and lighter.
