I've got a 2007 LS and I haul 500lbs or more everyday for work. I have searched throughout the threads and haven't found one that mentions springs that could hold that kind of weight. Perhaps I missed it. I would like to either keep the same ride height or mabey a little higher. If anyone has a suggestion I would appreciate it.

 

Look at Rockauto for "progressive" springs. They are reasonably priced at around $50 a pair.

 

I have a pair of canuck motorsports springs that worked well, I had a couple trips with 900lbs of laminate flooring in the back, it would almost bottom out over large bumps, but it was better than stock springs. Stiffer springs meant a bit harsher ride without the extra weight in the back. I may be taking them off soon, if you are interested let me know.

 

just add air bags to the rear springs..that way when your empty it can be set back to normal...less then 100$..no mods..just jack, slip bag inside (thru coils) spring..add lines and done..I have my lines terminated behind the fuel door

 

Thanks for all the information. I'll check these options out and let you know which one I go with.

 

Woody. Where did you go to get your air bags?

 

Not Woody but he may be talking about the ones from Summit Racing.
Look up Airlift 60776
Hope this helps.

 

It did Vince. Thank you. Woody, How long have you had them in and how are they working for you?

 

somehow missed this..they have been in for 4 years and no problems..I ordered from JCW only because of price, I like em because they operate on low pressure..5 to 20 lbs makes all the difference. Between hauling a trailered bike..St Bernards and camping gear...a full size roll around tool box, I have to say they done good

 

I'll add a 3rd for air bags.
