Stock shock length - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**ThreeQuarter** · 08-21-2019, 06:43 PM

My ‘68 C10 has replacement HD (variable rate) rear coils from Eaton Detroit Spring. The rear suspension is entirely OE or stock replacement parts. I bought Monroe 32301 shocks and below is a pic of how far they can extend beyond the lower mounts when the pickup is unloaded. Shouldn’t it have more travel beyond it’s resting position? The next question is “How much?”

Anyone have recommendations for a better shock for this application (longer reach)? Where can I shop for shocks by their specs and not their applications?

Any thoughts?

I would expect to have more shock below the ride height. With no more than that much every time you go over a big bump at highway speed there isn't much travel before the shocks run out of travel and come up hard on the stops.
I went through a couple of Rancho shocks a couple years back due to a part number mixup and the shocks were bottoming out.

I suggest contact Monroe to ask them about that. They have an email tech support form on their website, or a phone number to call to talk to a techie.

I wonder how much travel your springs would have if you loaded 500 lbs in the bed, and then if you loaded 1000 lbs in your bed. The shock only has about a 6 inch total travel.
