This is my first post so bear with me.
I have read a lot about the TSB SU006-07 and would like some clarification from you seasoned Taco owners.
1. Has the TSB been offered against the 2011 model yet?
2. I have the 3 leaf configuration on my DC TRD Sport but don't fully understand if there has been a change to the leaf assembly for 2011 so the 4th leaf isn't necessary any longer.
3. I tow a bass boat and did notice some sagging in the rear but don't know if that is normal for a Taco or if I should go for the TSB (my Z71 never sagged in back with my boat hitched up).
4. What are the actual numbers on the leaf so I can compare to see if I have the old stuff.
Currently my top spring has the following painted on the top facing up:
CHI 48220-04191 LH 190710
Anybody know if I can/should fight for the TSB? I want it if I can get it and wondering if there has been some major redesign with the springs.
