depends on the year the one i have is 3 inches i thing the early falcon and mustangs ones are 2 1/2 i think
Just about 3" . Under rated rear . Holds up good on street cars . I never had a problem with them either !
*hijack* Can't find U bolts for my 8 inch.....I have the early mustang that steps down to 2 1/4", and the parts store is telling me the smallest u bolt they have is 2 1/2. Where can I get them?
id try a off road store, like one that specializes in lifting trucks and such. thay can prolly find any size you want....
