Hi, newbie here posting from the UK.

Hope I'm posting in the correct section.

Sorry I don't actually have a van, I have a 1973 Minnie Winnie on a B300 van chassis, so I think I'm half groovy at least cool

Anyway, to the point of my post which is a vanning type thing - I'm looking for ways to reduce front end road noise. I saw that the 1978 model year introduced front coil spring isolators over the top of the springs to reduce road noise (not fitted at all pre-78), so I thought I'd get some and do a retro fit. Problem is I can't find any info. listed anywhere except for much later chassis types, eg. Rockauto doesn't even list any isolators for '78 -->

So, has anyone put isolators on a pre-78 B series and if so can you tell me what fits? Or should I just measure the springs and go for something generic of the appropriate diameter (minimum extra lift) ?

I should mention that the earlier van based motorhomes (like mine) used the lighter front axle (even though it has duallies in the rear). Not sure if that makes a difference to spring size, but it does mean my front springs are more likely to be the same as all your vans out there.

Thanks in advance for any ideas.

Steve

I put these on my New Moog 7272 springs when I rebuilt the front suspension of my '89 B250

https://www.amazon.com/Moog-K160037...231&sr=1-1&keywords=Moog+K160037


I am not familiar with the spring size or frame pocket of a 73 b300.

From memory the interior radius of the 7272 coil spring is 4 inches and they are about 7/8" thick and the coil spring osolators above were not the exact same as those I took out. The originals had worked their way to the center of the spring and there was metal on metal contact. The design of the linked isolators above would not allow the drfiting towards the center.

Thanks - I need to get under there at the weekend and see what I can see. I think the tops of the springs are quite well hidden inside the upper arm structure, but I should at least be able to measure spring diameter/coil thickness.
