I was wondering who sells the helper spring shocks for the rear of our busses?

Sun Oct 01, 2006 7:33 pm

Napa #75598

But you will need 10mm longer upper bolts.

Are these coil overs that fit a bay?

Interesting.

What type of application would warant coil-over shocks? How do they compare to standard gas shocks?

Sun Oct 01, 2006 8:27 pm

A saggy butt..... poor mans fix for adjusting rear torson bars.

Gas shocks do not change the ride height.

CIP sells them also.

My 72 has a Corvair Motor and it is a lil heavier than the VW. I like the idea of a "poor mans fix" for my application!

Thanks for the napa and CIP lead!

Here's some information and diagrams, I compiled sometime ago:

My original standard and alternative replacement suspension dampers, including:

Monroe "Load Leveler" heavy-duty, "Radialmatic" rear damper & concentric, supplementary, progressive-rate coil spring (Monroe part No. LL 665), for 1972~79 VW Type 2s. This has been retro-fitted my British specification, 1973 VW "1600" Type 2. With the rear wheels off the ground, the "Load Leveler", is just a bolt-on installation, with no need to compress the coil spring.

I first bought and tried the coil overs on my 77 Westy back in 1994 and ran them for 2 years, trouble free, before posting about them to the type2.com list.

I have been seaching the type2 archives for the original post I made but all I can find are bits and pieces of it being quoted in other posts.

When I bought them, they were part number 58598 and then Napa subbed them to 75598. I had one fail about 2 years ago. Napa replaced it because it has a lifetime warranty. I believe Monroe makes them.

If you want to use air shocks, the number is MA758.

The napa part listed doesn't work anymore does anyone know of other options? Thanks

Wed May 14, 2008 12:58 pm

Anyone help!! Both treads on this topic that have listed part numbers with napa and monroe must be out of date cuz i called and had no luck. Does anyone know of current numbers or where you can purchase them coil assisted shocks for type II's. Thanks OneUglyNerd

The application is 1990 Chev Astro Van AWD. Going to Napa's website you get this: http://www.napaonline.com/MasterPages/NOLMaster.as...ter+-+Rear

after this page: http://www.napaonline.com/MasterPages/NOLMaster.aspx?PageId=430&CatId=7&SubCatId=10

Scroll down to Shock Absorber - Sensa-Trac, Load Adjuster - Rear

I googled napa 58598 and got this:
http://www.dmauto.com/web/dmauto/Catalog/NAPA_ECAT/mfg/NS/58598/# for more $$ than from Napa......

I managed to get a close picture of an original rear heavy duty coil over shock,when I had the chance.

I really like to know what brand were the originals 211.513.031M , Monroe, Koni...?

I will be grateful for any help you may provide.

Mon Sep 30, 2013 8:22 am

Both pairs took me a truly long time to track them down.

If a T2 owner or a member is interested the part numbers direct from Koni are as follows:

There is a slight difference in length:

T2a [8000e-1082] on a T2b:

Thank you for your time.

I recall reading that you should be careful with using coil over shocks on the back of a bus. Especially if you have rust problems in the shock mounting area. The mounting point for the shock is only designed/engineered for regular shocks and a coil over could pull the mounting nut out of the inner fender.

Winner winner.

I fixed a Bus that had coil overs on the back...completely destroyed one upper shock mount.

Its a really tricky subject of getting non specified coil overs or even shock absorbers under our baywindow.

If a shock absorber has less maximum stretched or minimum pressed length, then we have a problem.

Lets take for example Part Number: NS 58598 from Napa with specifications:

http://www.napaonline.com/Catalog/CatalogItemDetai...0413796210

Shock Compressed Length : 14.625" around 371.5 millimeters

Shock Extended Length : 22.125" around 561.9 millimeters

In comparison for example with the specifications of rear Koni's from Richards site:

http://www.ratwell.com/technical/Koni.html

Model Year-Part Number-Location-Valving-Max Length-Min Length
68-69 - 80-1966 - Front -1100/600 -419mm -217mm
68-71 - 80-1967 - Rear -1250/600 -561mm -347mm
70-79 - 80-2110 - Front -1350/600 -414mm -272mm
72-79 - 80-2220 - Rear -1250/600 -581mm -358mm

We may all see that a compressed length of 371.5 wont allow the bump stop do its actual work, instead the shock will be pounding both mounting points/ends.
The shock absorber wont let the bus get firmly down to its lowest point.
Same thing goes the other way around on the boomerang plate, specially on a T2b

From Cip1 store and the info provided :

22-1/4 maximum length, which is around 565mm, is good enough for a T2a application.

I just hope travel length is greater than 8.5 inches on those, since (565mm overall) minus (347mm compressed length of a T2a) comes down to 218mm which is around but greater than 8.5"

All the above compared from Ratwells and koni info.

If another member knows the exact measurements from the upper mounting point to the lower on T2a and T2b please do post them at this topic.
