Shock Absorbers

Good day to all.

I know this will bring about many inputs, but I have no history data on the shock absorbers on my 2010 Cascadia. I have cupping on the drives and have heard, read and been given advise on the reason for the cupping - the shock absorbers.

A little info on the truck and wheels: I purchased and installed CENTRAMATIC on all three axles - this improved and almost eliminated all the shaking. I have brand new Goodyear steers,less than 5K miles on them. I had a three axle alignment performed.

The 2nd and 3rd axle tires have plenty of meat on them, however, they appear to have mixed and matched Goodyear's (same model); when I purchased the truck.

I am torn on whether or not to have the drive tires cut for obvious reason - reduction in life. However, do want to eliminate the cupping.

So, which shock absorbers do you guys suggest are worth the bang for the buck, and let me hear your thoughts on cutting / rounding the tires? My loads are normally HEAVY loads (40-45K) - in the event this matters.

thanks,

 

I was speaking with a Freightliner Tech that worked at an Elite Freightliner and this is what he said, "Sachs manufactures the shock absorbers for OE Freightliner. The reason the OE shock differs from regular Sachs shock absorbers[price is that Freightliner slaps on their OE part number on it, but there is no difference in the regular Sachs shock absorber" - which is substantially cheaper. Any thoughts on this comment from one of thier techs?
