25.1 is for 6.0-7.49 e.t weighing 2800lbs
25.2 is 6.0-7.49 e.t. weighing 3200lbs there are alot more required bars and larger sizes required for 25.1 and 25.2 they also are required to be moly where 25.4 and 25.5 can be mild steel so if you want to go faster than 7.50 mild steel is a no-no.

hop that helps,
Justin
