I haven't ever had any hopping with this setup. This is a very smooth ride, even on pot hole riddled roads. I should note my truck is a 2wd (don't know if that matters to you)

I believe the A is the 3500 lb Spring. The 2nd letter may be the Arch. I believe the base shortbed regular cab 3.5 Ti-VCT at 4050 Curb Weight and 6010 GVWR will have the 3500 lb Springs with the lowest arch.

Any idea where this can be confirmed and/or difference in arch height between the G and H?

Fyi spoke with manager at Tasca and they said the G or H ar end of part # is engineer # amd the part itself is exactly the same.

Okay, so it's not the Arch.

"Exactly the same" confuses me though.
Why assign a new Eng. # to a part that hasn't been revised?

i asked the same thing he said they do it all the time with different parts with bo good explanation. Could be based on mfg date etc .. Arch is the same tho which is all i was concerned with. Getting put in nedt week

Hope it works for you. I have the lighter springs (6500 GVWR with 3300 GAWR) and haven't had any real complaint about the ride but then the only other 15+ I spend time in is a 7050 GVWR but it's 300 lb heavier and holds 83 lb more fuel and has a 157 WB which means it's not really comparable. If anything I think it rides smoother but that may be the wheelbase.

How did this work out for you? Do you have the part number of the springs?
