Opinions about original helper springs - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Metalaroundstone · 10-16-2013, 03:38 PM

I am thinking about finding and installing a set of original helper springs to beef up the load capacity of my 66 c10 lwb. I carried a full load of compost the other day and the bed really angled down in the back. I would like some opinions about how well these helper springs work, and any ideas on where I could get a set. I think this is what one of the springs looks like.

You will have to find the rear end that has the bumpers on them for the auxiliary springs to rest on....I have a pic somewhere...let me look

1963c-10 · 10-16-2013, 04:15 PM

Heres some pics of the mount that goes between the trailing arms and the rear end...the springs will rest on these and mount to the frame

Thanks to help from this forum, I was able to get the right helper springs from my truck, but the rubber mounts are pretty much toast. Where did you get what looks like new rubber bumpers shown in this picture you posted?
Thanks

Great. I didn't even think to look there for some reason. Thanks.

The springs in the top pic aren't the factory helper springs. The springs in post #3 are.

1963c-10 · 10-16-2013, 07:51 PM

I wouldn't mind finding a set myself.

1963c-10 · 10-16-2013, 08:31 PM

Heres a better reference pic Woogeroo. These pics are of a truck that 5150 parted out a few months back.....i missed out due to my schedule, but I'll come across another set soon...hopefully.

**jayoldschool** · 10-16-2013, 08:55 PM

My 65 has them. Going from memory, the GVW is higher for trucks equipped with this option.

They are good for an extra 500lbs per each side.

1963c-10 · 10-16-2013, 09:41 PM

ive got a data sheet on them somewhere in my stack of books...ill check through them this weekend if someone else doesnt have them.

1963c-10 · 10-16-2013, 09:56 PM

ive seen them in the single leaf and triple leaf design. i think the single leaf was 67-72 though, maybe someone knows more specifics

1963c-10 · 10-17-2013, 11:35 AM

Here are some pics of a single leaf design that I came across last night.

1963c-10 · 10-17-2013, 04:11 PM

Ill get the part numbers posted tonight. Ive seem them listed as auxiliary springs in my literature. Found a nice set last night, shortly after posting that I wanted a set. Should be enroute as we speak.

**aerotruk63** · 10-17-2013, 05:47 PM

1965 GMC used Timbren Rubber Springs for leafspring overload

1963 Custom Accessories Book.
1 part number for both 10 and 20 series.

1963c-10 · 10-17-2013, 07:35 PM

is that a short bed frame? i could use some mounting measurements

63burban · 10-17-2013, 09:37 PM

Long box 3/4 ton 1965

**jayoldschool** · 10-17-2013, 10:40 PM

My 65 (LWB C10) has the multi-leaf springs. I'd never seen the single leaves until this thread.

**jayoldschool** · 10-18-2013, 06:45 PM

No problem, I'll shoot some tomorrow. Bed's off, too!

1963c-10 · 10-18-2013, 09:02 PM

67-72 models had the single leaf from what ive seen and the triple leaf in 60-66. just from what i gathered off the 67-72 threads...but the frame and rear ends were thhe same, so i dont see where either model wouldnt work just fine

1963c-10 · 10-18-2013, 09:03 PM

and the mounts look the same, the springs are reproduced, so i imagine you could always put new triple leafs on...lmc shows the same part for 60-72

next concern is figureing out placement of tow bar, factory rear tow hooks and the overload springs...this will be fun

Hi guys i just signed yesterday COOL. Anyway my 66 SWB has the Auxiliary Spring equipment installed from the factory as shown in my SPID. Unfortunately the passenger side support plate was broken many years ago. I have acquired a NOS set from Ebay about a month ago but i haven't been able to located the rubber bumpers that 1963c-10 posted in this thread. The P&A 31 parts catalog does not list the part number for rubber bumpers and I am in dire need of some new ones. Any suggestions
