NAPA/Monroe p/n 555002 is what Holsclaw trailer owners can use to replace thier old shocks. You may also want to pick up shock bolt kit 650-1100 (1 kit per shock). The shocks come with 1 bolt kit, which I used on the bottom eyelet(s). I did have to cut off about 1/2" on the end of the bolt(s) so it would fit properly.

I used the NAPA bolt kit(s) on the upper eyelet. No modification required here.

Hope this info helps...

Thanks Hobie,
How about the springs? To hold up a 16' Whaler. Size? Lenght? How many coils? Where to get them? Part number? Sombody out there on this forum must know the answers to some or all of these questions! Thank You , Andy

Yogi: Here is some info regarding the springs that are on my trailer.

O.D. 3".

# of springs 4.

Wire dia. 6/16".

# of coils 10.

Ends of coils appear to be closed, and are not ground. (spring shop will know what this means)

Free length- Unknown. My boat is on the trailer right now. So I can't give you what the free length would be without the load of the boat. Compressed I have 6".

Keep in mind that the springs on my trailer are 28 years old, and have flaked material off (rust) so the actual wire diameter may be closer to 7/16", or even 8/16".

If I were you I'd find a local spring shop, and give them a call and explain what you are trying to do. I would also have the NAPA/Monroe shocks available.

Hope this helps..

Yogi: I have some additional info that may help you out some. I was out in the boat today, and with the boat off the trailer, took the following measurements. The free length of the springs was 7 3/4". I also measured the distance between the center of the shock eyelets and that was 11". As the OEM shock that Holsclaw used, is 12" at maximum expansion, I'm going to guess that free length for a "new" set of springs would be around 9" or so. For what it's worth, the p/n for the spring is HB-9. Perhaps the 9 in the p/n could be the springs free length. The p/n is different from the other p/n's used on the owners manual that I have. Again, your bet bet is to work with a good spring shop in your area.

Hope this helps..

Hi Andy..555002 is listed as a RV shock. My local NAPA jobber had to call Monroe as it was not listed in his catalog. That's where he got the p/n. He then ordered it from the regional warehouse in ME. Delivery was the next day.:-).

Check back with your jobber, or with another NAPA store. If you still have trouble, post it and I'll get you my NAPA guy. He'll help ya out I'm sure.

Hey: I'm outfitting my first aid ditty bag. I need something for burns..I read somewhere a few years back that there was some sort of new cream, salve or ointment ??? that FF were using to treat 1st degree burns. The article reported that it was so much better than the other topical treatments on the market. Specificially I'm looking for pain relief. Might you know what that stuff is ??

Let me know bout the shocks..
