Have you noticed how overloaded the factory springs are on a 292BHDS? I upgraded this week due to a broken one. I can't believe what they install coming off an assembly line.
The picture shows the broken one, the flat factory one and the upgraded spring and U bolt.
Took about 2 hrs after I had jacks and tools out and ready. Pretty easy job with air tools. Call me if you have any questions. After the one broke and seeing how flat they were it was a no brainier to replace.
