Rear Shock Installation

I purchased the KYB shocks from Rock Auto ( PN KG5517). and I must say I'm very pleased with them. The ride is very smooth, but feels firmer and more controlled. I had done the fronts about a year ago, and today I installed the rears. I know you love pictures so here's a little tutorial.

First remove rear carpet and access panels to trunk area.

Next I loosened the shock tower bolts (13mm) just a little.

Put the car on ramps

and removed the lower nuts from where the shock goes through the trailing arm. Two nuts lock nut 1st (17mm), then 19mm nut.

Note: used a vice grip to lock the shock shaft from turning.

I then pulled out the shocks from inside the car.

Disasembled them by pulling the rubber cover off of the top.

And removing the nuts holding the shock top on ( both 17mm)

I then used the hardware that came with the KYB's and reassembled the shock top onto the KYB, was worried that it might not fit , but no problems.

Getting the new shocks in is a lttle challenging,because they are gas shocks and expand to their full extension once you cut the shipping tape, so here are a couple of tips.

1. You have to loosen your top to get more clearance,

The rest of rear shock instal

Tip number 2 is as the result of the shock being at full extension once you get it in the car. Note how tall it is, but make sure you have the shock shaft through the hole in the trailing arm below.

Tip 2 have someone lift the rear of the car untill you can get the bolts started

Ok Next tighten everything on top of the shock down. Then install bushing and lock nuts under/in trailing arm.

And drive.

Great write-up and photos! Does that same KYB part# fit an '88 Spider do you know? Rock Auto doesn't show Alfa applications. What's the part# for the front? Thanks!

KYB Front shocks part# KG4616. Shocks will fit Spider and GTV, 72 on and Sedan 72 to 74.

Great write up!

Additional tip: I used Duct Tape to hold the shocks compressed a couple of inches, left a tab for its easy removal after installation.

Best regards, Elio

Good tip. If I hadn't been using wheel ramps, and had jacked the car up, or put it on Jack stands, there may have been more clearance, but if not I would have had to come up with something else (like your idea). As it was I was stumped until I leaned into the trunk, and noticed the car sag down. I then found I could lift the car to the point where I could have started the bolts ( if I had an extra arm).

Gadwhite,

Now that you are some years into the KYB shocks would you recommend them? I am about to swap out all four originals on an S3 Spyder and these appear to be really attractively priced! Rock Auto still has the same part numbers and I would hope that they refer to the same shocks.

If the threaded portion is open could you just use a cupla longer bolts tp pull that interior mount down and secure it? A set of KYB's is on my todo list for the 87 Quad.

Did you put on all 4 KYB's #KG5517 or just the rear shocks. Since my records show #KG4616 as the KYB's for the front.

Front and rear are very different. The duct tape trick is very good and does the trick.

Thank you gadwhite!

Using your notes as a guide I replaced my 1974 Spider's rear shocks with Koni Classic Reds (Part 80 1781).

A few notes based on my experience today:
  • I found it easier to work after removing the rear wheels, as it gave better access to hold the shock absorber while loosening/tightening the nuts under the trailing arm.
  • Tip: Use a strap wrench to hold a Koni while loosening/tightening the nuts under the trailing arm. (Did use a vise grip to assist in the removal of the other SPICA shock absorber. Mismatched rear shock absorbers courtesy of a previous owner.)
  • Tip: Use a twist tie or rubber band to temporarily hold the washer and bushing on the bottom of the shock absorber during insertion; it can be easily removed with needle nose pliers prior to installing the remaining components under the trailing arm.
