Rear Shock Recomendation - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Frizzle Fry · 12-15-2007, 11:54 AM

I'm moving my rear shock upper mounts in and will be replacing the shocks to increase travel. I need a minimum extended length of 19.75" and a max compressed length of 13.5" but would prefer more like 20" ext and 13" comp. Any suggestions? I have an email in to KYB but I figured you guys might have some good recommendations.

If you go on monroes website you can look through their shock dimension guide and it will tell you if a shock like that exists, and then you can reverse look up the app from the part # andfind out what it's for and order shocks from whatever manufacturer you wish for that vehicle.

speedway motors lists shock dimensions in the catalogue

That sounds close to the dimensions of the rear shocks I swapped to on my 68 Beater. I used some Bilsteins for a 88~98 Chevy w/a 4/6 drop (that was their catalog ID). The install required a custom (homemade) upper bracket & 3" more travel vs. a stock 67~72 GM rear truck shock.

Tomorrow I'll try & find the dimensions I documented out in the garage to confirm the exact measurements.

I used the mounting chart then the dimension chart to find the shocks I needed. The ones I got for my truck are the Monroe Sensatrac PN 5850. It has an L2 top mount and LS47 lower which matches the factory mounts, a compressed length of 12" and extended length of 19". It was the closest thing I could find and is actually listed for a Corvette in the application guide. Hope this helps.

I started my search using the same logic.

What concerned me was that I find it hard to believe all shocks are valved the same (from the same product line/manufacturer). Does any shock that fits have the right valving for my swb truck application? I decided that I would look for truck applications that were real close to my needs.... a 88~98 4/6 dropped Chevy seemed real close. I did have to refigure my shock bracket travel on the truck but it was worth it to me to have the same type shock F/R.

Just a thought.....

No, but as you indicate... once you find a part number that "fits" you have to dig into the original application to see if weight, etc., are "appropriate."

The numbers I posted above are both for 1/2 and 3/4 ton truck applications... the one I chose is actually for a Frod pickup

Obviously, we both had the same brilliant thought process. But..... I selected a shock for a Chevy truck & you picked one for a 'Frod'.

I'll let the rest of the board decide your fate . . ......

I'd been looking at the 5850 shocks as well but came up with 9.5" comp and 14" ext.4.4" of travel. L1 and ls14 mounts corvette
Also a 555003 with 9.6" comp and 14.75 ext 5.1" travel RV shock

Just wanted to close the loop on this and say thanks again for the input.

I ended up going with a Monroe Sensa-Trac 37037

No more shock limited travel. I have almost 10" of rear travel now

That's more than enough for my purposes.

That's a 16" ruler:

Now I need to do something about that exhaust...

Good choice!

And that KYB looks like it's got another couple hundred thousand miles of life left in it

Those KYBs were f'n hosed from being over extended by the bags. One actually started leaking

Although your application is a little different from mine, I'm curious, if you can remember back to when your KYB's were still working, how they compare with the Monroes for ride. I've always had KYB's in my cars, but was considering the Sensatracs for my stock truck, thinking they'd provide a slightly more comfortable, if less performance minded, ride.

Frizzle Fry · 12-16-2007, 08:33 AM

Right on guys! I really appreciate it. And I'm more edjumacated now too :P
