Anyone know where to buy suspension parts for a 1975 Competitive trailer? The one under my '71 Sanger flat rides horrible. The the bow eye brace bolts at the trailer stress and break due to the boat moving around on the trailer. I strap the boat to the trailer just like my cousin does his flat and he never has a problem. Either my suspension is shot or maybe the tires are too stiff??

Any ideas where to buy suspension parts?

Thanks, Alan

Are the bunks adjusted properly to fit the bottom of the boat? Almost sounds like its tetering on them. Just a thought.

I just looked and both bunks are flat against the bottom of the boat the whole length of the bunks.

When bouncing the suspension, it sounds like a bed at a cheap motel..squeaky, squeak, squark, squeaky.

...I have a '75 Competetive.....I found that the positioning of the boat,...front to back,....is key.......The arm that goes to the bow eye should be adjustable.......Just a guess but you may have the boat to far forward???......

Make sure all the shackles and moving parts are free'd up. Try some lube????
I'll put proper lube tomorrow, but spraying some PB Blaster on all moving suspension parts seemed to help a little (just bouncing it in the garage).

I noticed all the suspension pieces are labled "HADCO". Appears they are still in business in Corona, CA.

Boat is blocked in by my daily driver truck that has no engine/tranny at the moment so I can't tow the boat anytime soon.

Interesting. I know the bow eye arm is not adjustable. Not to say it couldn't have been moved in the past. Cav plate hangs past the bunks. The boat is a 19 ft. Family Ski bubble deck.

I've owned the boat since 2004, and this problem is beyond rediculous. I mean I see some of the worse beater boats ever driving down the freeway, and I can't even make it 20 minutes from Sanger, CA to Pine Flat without the boat getting all sidways on the trailer. I'm mechanically handy, just need some guidance from you pros that have been down this road :)bulb

Thanks for the ideas so far. They have definitely helped.

Is your trailer made from rolled steel or heavier channel steel? Rolled steel will flex alot more than the channel aggravating the stiff suspension you prob. have from lack of grease in the shackles and equalizers. Make sure everything that is suppose to move does and if that doesn't solve the problem dissassemble the leaf springs and clean the rust and crap that prevents them from moving smoothly against eachother. It doesn't help that the roads are pure crap too.
