Shopping for Shocks (KYB) for the Falcon (opinions please)

Post #1 by CoupeBoy » Wed Apr 08, 2015 11:38 am

On my Falcon I plan on replacing the shock tower caps with '68 "standard" Mustang units. Two bolts instead of a single pole.
This morning I got an email from Amazon that KYB kits were on sale (prices seem no different than other times I checked, but I clicked anyhow.)
KYB GR-2 (set of 4)$79.00 & FREE Shipping
KYB Gas A Just $132.00 & FREE Shipping

So being the person I am, I decided to check online for comparative prices. Rock Auto has them for slightly less
KYB Part # 343219 GR-2 / Excel-G $17.19 ($34.38/pr)
KYB Part # 343146 GR-2 / Excel-G $18.50 ($37.00/pr)
$71.38 (plus shipping)

Or
KYB Part # KG5517 Gas-A-Just $31.89 ($63.78/pr)
KYB Part # KG4517 Gas-A-Just 31.99 ($63.98/pr)
$127.76 (plus shipping)

Additionally Rock Auto contained a link to KYB website
$40 rebate on purchase of 4 (have to be on the same invoice)
$40 rebate for 4 -- kyb.com

So this month seems like the time to buy shocks, GR-2s for only $10/each... can't go wrong there.

I've read a couple forums and threads and it seems like the Gas-A-Just shocks are the way to go, but there was another that I read somewhere that said he had to swap out the Gas-A-Just for GR2's in the rear to control some wheel hop (cant find it now)

Up until now I've been using generic store brand or lower end Monroe or Gabrial gas charged shocks, basically off the shelf units at the local parts store. So any guidance toward one or the other would be appreciated.

My experience with KYB Gas-adjust shocks is they can be a bit stiff for cars with a light rear end, causing rear end bouncing over rough roads. I love them in the front though. So on heavier cars I've used them on all 4, lighter cars I've used traditional style in the back or on all four.

Ride quality seems to be one of those black art items..
You want just enough spring rate to achieve the desired ride height
And just enough shock valving to dampen spring oscillations and control bounce.
Not too stiff, not too soft, and with enough capacity to absorb multiple bumps without overheating and fading.

When you say 'Traditional Style" are you talking about oil bath? vs Gas charged?
And can I assume that means GR2 vs Gas-A-Just?

thanks again,

KYB is good: Gas Adjusts R stiffer than GR2 -
Bilstiens R Beddah.
(not sure the model 4 U)
AND more expensive I'd assume.

Coupe just a heads up I did the same thing on my 63 Ranchero. Concerning the tower cap/ shock mount. I ended up having to cut some small pipe to make spacers between the tower cap and the shock tee top, about 1". Without the spacers the shock would bottom out before the suspension.

Thanks for the heads up, I've seen other modified shock caps where the owner cut them and added in material to make the shock cap itself taller too, so I've got a couple options.

Now if only my other projects would quit filling up my shop...

Like my QA1 double adjustable shocks can dial them in for the drags, autocross, open track and street in short order. Best to order the coil over version even if not using coil over springs just for the future. They are also rebuildable.

My '62 Falcon came to me with KYB GR2s and they've been fine. I'm not really a fan of KYBs in general, but you can definitely do worse. They break down quickly on rough roads or with spirited driving, but as a shock to cruise around on they do their job and seem to last.

It's springtime, so it's Koni's annual spring sale now if not soon - if you want a genuinely good shock that might be worth looking into. Red Shift Motorsports will order and drop-ship just about any shock Koni makes at an excellent price. If you want a real improvement, I'd consider that option.

These guys?
RedShift Motorsports-- "Honda/Acura Race and Performance Specialists Since 2002!
I'd assume that I need to know which part numbers I need since they appear to not specialize in old ford uni-body cars.

I'll have to look into it, but it looks like Koni has at least 2 different styles of shocks.
