Google Kenworth truck spring replacement, it should give you numerous hits.

 

@spsauerland might be able to look something up.

I have a very hard time believing that they would discontinue front springs for a 13 year old truck considering there are thousands of those trucks out there still. More than likely they probably updated them to a new style (I think KW went from threaded spring pin bushings to rubber pin bushings around '06 or '07).

 

Post last six of VIN and I can dig a little deeper if you want or need me to.

 

Your OEM spring number is HK48110-3139. It is a 2 leaf taper springs with rubber style bushings. Not really crossing over to anything in my books. My books are older and don't show many with rubber bushings, only threaded. Good spring shop should be able to cross the original P/N.

 

When I put new springs on the wife's Suburban, St. Louis Spring Co got the job done. They manufacture the springs, and can custom build to your specs if they don't already have the measurements. I ordered 3/4-ton +2" for the front and 1-ton +2" for the rear, and they went in real easy. Website says they do heavy duty and trucks, so might not hurt to contact them if you're not having any luck elsewhere.
