I had an 88 2500 6 lug. If I remember correctly the 6 lug is a 7200 gvw (light duty 2500)& the 8 lug is an 8200 gvw (heavy duty 2500). It was already lifted so I don't know what kit it had.
That is almost correct. It is 7200 or 8600 GVW. GM did that from 88-98. No matter were you go for your parts, If it matters they are gonna ask you if its 7200 GVW (light Duty) or 8600 GVW (Heavy Duty).
