Leaf springs & Koni shocks on our '89

December 01, 2010, 09:50:12 am

Would Koni shocks be of any benefit on our '89 Oshkosh chassis with leaf springs? It do ride a bit rough. I think Oshkosh uses the same chassis on their garbage trucks. The ride is a bit choppy on concrete roads.

Leaf springs are the cause of the harsh bumps, etc.  Nothing can fix it. All new shocks will help, but you may or may not notice the change. Leaf springs rides are completely different than air bag rides.

Thanks Barry.

I thought the same thing. Guess I will just bite the bullet and tell the DW to go ahead and order that Dolly Parton Industrial Strength Military Grade Kevlar Covered Graphite Strung Double Slingshot Support Garment.

If you are not already doing it, lubing the springs might help a little.  Some recommend motorcycle chain lube.  There are shops that repair and recondition leaf springs.  Found this and lots of other stuff googling "leaf spring maintenance" http://www.ucfamerica.com/UCF%20WEBSITE%20LITERATURE/Leaf%20Spring%20Failure%20Analysis.pdf  My previous SOB had leaf springs that sagged so much that I added helper air bags to get it back up to the right height.
