Toddgilroy and I have been PM'ing about these shock absorbers and I want everyone to see his questions. He said:

"I did order the OESpectrum 37191 you recommended for the rear from Rock Auto, and also ordered the OESpectrum 5801 for the front. All for less than $100, including shipping!

Do you think having light truck/SUV shocks on the rear and passenger car shocks on the front will cause issues?

I did find an old thread referring to Gabriel Ultra shocks (G63375 & G63398) that worked on a 60 SB, and their OEM use included older police and taxi cars and more current HD trucks and vans. Wondering if having "matching" shocks would be better?

Thanks!
Todd"

As a side note, Todd expressed his heartfelt 'thanks' to John Pizzi for all his help. Furthermore, Todd said it is very evident that John is a great mechanic for many years. He may have said a few more nice things about you John, but I'm trying to prevent a massive kudos-syndrome attack of high emotions during the holiday season.

Todd, I like to put things in perspective. Back in the day, it seems like everyone sold shocks (mufflers, tires, brakes...) for our cars because there were millions on the road. Most places gave upgrade choices that proved to be better than OEM and backed by a warranty.

Now that our classic cars are few in numbers, so are parts choices. If an auto parts store doesn't move parts fast, he lets the warehouse put them on their shelf, not his. It is rare to find cross reference books that include cars from the '60's.

Our classic cars are heavy. New cars are not. The closest vehicles (in weight) to our cars are some SUVs, minivans and crossovers. These vehicles use parts suitable for our cars. So the question, 'will our cars ride like a truck with new SUV shocks?' Not at all. Your springs hold up the car and provide 'bounce'. Shocks regulate the stroke rates by metering oil, both up and down.

OEM shocks only lasted about three years but they were inexpensive. More money buys better parts that lasted much longer. We are limited by space for the front shocks but not rear shocks. SUV shocks have a large piston and the outer diameter is 2-1/2" which allows these shocks to last longer. They are capable of more severe service than a Thunderbird demands.

It is probably best to 'match' the ride front-to-rear, but I don't think it's critical because both are different systems; independant and solid axle. - Dave

I'm not sure what I did to deserve Todd's kind words but I'll certainly accept them. Thanks Todd.

Great info guys - thanks!

My car rides very nice (new Monroe shocks about 10 years ago). Only complaint is when I hit a big dip or bump on the interstate (70ish MPH) the first rebound is like not having shocks (big bounce) then it recovers nicely.

And if you look at my Avatar - that is the Tbird stretching it's legs on a race track this past summer! Talk about some body roll......

I'll be looking into a set of these shocks for sure.

Did they come with a lifetime warranty?

I got a pair of shocks for the rear of my '66 'bird from a supplier about seven years ago, it might have been T-Birds by Nick that I got them from.

After removing the leaky air-shocks and fitting the new ones it improved the ride and handling 100%.
But I notice if I go out to the garage and the car has been sitting for a a day or two and I bounce the rear end down and up it takes one cycle before the shocks are firm again, that first bounce is like they have gone soft.

However as out roads aren't as smooth as yours the shock are always working - so they stay firm when driving.!

Sorry, haven't been on here for a couple of days and missed some of this discussion. First, a little background about me. I'm not all that computer savvy, so please bear with me. I've been a mechanic of one type or another all my life. US Navy 4 years, as a hydraulic/airframes mechanic ('71-75). Worked several mechanic and welding jobs for a few years and finally settled down as a hydraulic mechanic at the telephone company (GTE, which finally became windstream). So, hope this qualifies me for my opinion on this. Anyway, thanks to Dave's research, I got those rear SUV shocks, and used the Monroe Reflex shocks on the front, as listed for the T-Birds. I think they work very well together. Drove it over about a 25 mile test drive, curvy, 2 lane country roads. Handled great. Not a real firm ride, but really just fine for me. I don't like that floating type ride you get with a big Cadillac, and these shocks don't give that. Someone mentioned a big dip and not much shock action when first hitting a big bump. These don't do that. If you hit a big dip, or bump, like first going onto a bridge say, and a a pretty fair speed, the shocks will give enough to be real comfortable, then rise back up and settle there. No bouncing. Just down then back up. Lots better ride than my 05 Mustang or my Jeep GrandCherokee.

Default Thanks Jimmy, for your critique on Monroe shocks.

Jimmy, I can't thank you enough for your response. I hope this guides many Squarebird owners toward the ride they are looking for. With your mechanical background and experience, you already know how 'good shocks' should perform, and you also know what 'junk' to avoid. I agree with you that there should be NO bounce, but a controlled damping to stick the wheels to the road for better braking and handling.

Two main factors caused me to mention these shocks; price and performance. I also look at 'warranty' as an important part of the price. I find that good durable parts usually come with a decent warranty at no extra charge.

I found about six candidates but all were more expensive. This is one of those rare instances where 'the cheap one' IS what you really need.

I am upset with Monroe. They are (or were) based in Monroe, Michigan (so was Gen. Custer), just south of Detroit. They have a great reputation for producing quality shock absorbers for over fifty years. Now, they don't seem to care about misrepresenting their products by showing a wrong picture. I was so upset, I emailed Monroe. They never returned my email, so far. My concern is, I'd like these shocks to be around for awhile. If folks don't know this is the right part, nobody will buy them. - Dave

I got the Monroe shocks installed last weekend and after waiting for the snow to melt and roads to dry up, I took it for a short drive around the neighborhood today. New shocks (plus some torque box repairs) make a big difference stopping, cornering and going over the neighborhood speed bumps.

I put Monroe 5801 on the front and Monroe 37191 on the back.

To keep things in perspective, I think my 12 year-old daughter could probably expand/collapse the old rear shocks with her hands...they were shot! Front weren't much better.

Can't wait to do the springs and sway bars next (front & rear on both). Original upper ball joints will be replaced, too, along with the control arm bushings, etc.

Thinking about doing the disc brake conversion while I have it jacked up and torn apart.

Thanks for the suggestion on the 37191.

Thanks Todd, that reconfirms our findings. Kentucky and Nebraska say that their Squarebirds run great on Monroe 5801 shocks on the front. After digging, I found this shock works on ALL Squarebird front ends when mounted in the center of the springs.

Monroe 37191 shocks work well on the 'leaf spring' Squarebirds (1959-60). I am still looking for good rear shocks for the '58 'birds.

The other good news is, these shocks are in production and as such are inexpensive. Rockauto.com sells them both:
Monroe 5801 -- $21./ea X 2 = $42.00
Monroe 37191 - $26./ea X 2 = $52.00
$52 + $42 = $94 (minus 5% discount $4.70) = $89.30 + shipping. - Dave

I spoke with Pablo at Monroe (down in Mexico, not in Monroe, Michigan) and rockauto.com.

Monroe says they will fix their picture.
rockauto.com says that Monroe discontinued the 37191 shock absorber BUT they still have 40 shocks in stock. Hurry and get your order in before they're gone.

rockauto.com was very specific about fitment. They said, 'that information comes from the manufacturer' and they will not simply add a part to our car's listings. RA said they make the manufacturer take responsibility even if the parts fit (whatever that means). The guy was very 'guarded' in his conversation and he really had no help or alternatives when I asked if Gabriel has a replacement. Like always, we're on our own. - Dave
