The last thing I need to complete my parts list for my suspension is new shocks. All these parts are REALLY adding up so I'm looking for some good bang for the buck shocks which brings me to KYB.
Mustangs Unlimited has both the Gas-A-Just's and the GR2's, what are all your reviews? I've heard the Gas-A-Justs are good, but might be too stiff for 620# front springs and 4 1/2 leaf rears. I want the car to be stiffer, but I don't want to be bouncing all over the road either.
Based on the descriptions it seems the GR2's are not as stiff, but are they too close to stock? Anybody know? One thing I really like about them is they are even cheaper than the gas-a-justs, about $60 cheaper.
I have the Kayaba Gas-A-Just on my car, which has been upgraded to 66 Shelby specs. An excellent performance item for the crappy roads around here. IO used to have Koni's, when I lived down south, but too harsh for around here. The Kayaba GR-2 is a nice OE style heavy-duty shock if you want original ride quality.
Ok thats what I was wondering. Based on the descriptions I have found the GR-2's were a little stiffer thank OEM but it never said by how much. I just don't want to have too soft of a shock and then be bouncing and floating all over the road when I hit a bump. But I don't want one too stiff either because it is my "daily driver", and I don't want passengers to hate the ride of my car haha
Last night I drove a 68 with stock leafs, 620 fronts, and Gas-a-justs.... this morning I drove my 65 with stock leafs, 620 fronts, and GR2s. In my opinion from this comparison, there was no discernable diffence in ride quality or handling.

I've got 550 1" drop springs and 4 1/2 mideye leafs with GR2's all around and the ride is fine, not jarring, not soft, no complaints when my daughter rode in the rear, wife up front. It's a sporty enough ride for now until I can afford or need Koni/Bilsteins.
Try to stick to your budget, the shocks will be $100, if you want a 1" etc. front bar = $100 still less than $320 at once and I don't think you'll need a rear bar for a street car and they can actually induce snap oversteer from posts I've read, most only use them on track only cars where they can dial them in and run at 9/10's.

ive got the gas a just's all around and like them. but my front is still stock springs. i think with the new springs it would be ok.. im going to probably get a lower spring rate though. depending on how your adventure goes.

You might consider running Gas-A-Justs up front and GR-2's in the back, like Jon. Most of the ride comfort issues I had were gone when I replaced my rear shocks. The fronts run smoother with the Edelbrocks for sure, but I didn't have as much problem with the front skipping around as the back.
I am running 620's in front and 4.5 leafs in the rear. i have the GR2s and think its fine. i mean it is a daily driver for me so i wanted a sporty handler but a smooth ride and i think i hit it just right.

I suppose that is an option, but I'm really tempted by the the cheaper price of GR-2's Will the 69's heavier front end have a large affect and make the GR-2's too mushy? If this is a possibility then I might just do the gas-a-justs up front and GR-2's in the back...
Well its good to hear that some of you guys are running the GR-2's so I know that at a minimum they will be decent enough for what I'm going for. Now I just have to decide if I want GR-2's all around or just in the front...
I'm probably going to be ordering my front end stuff in the next few days along with the 4 shocks. Then I'll order my leaf springs and new shackle kit hopefully shortly thereafter, can't afford that extra $250 or so right now but we'll see!
I picked up a set of the GR-2s for the rear from amazon this week for $33 total with their free shipping. I just got them today so I can't say how it will handle, but I'm replacing everything a little at a time as I get the funds, so I'm still on stock leafs and stock front suspension.
