I'm also a Alterkation user...Started out running 6 oh's and now 4.80's in the 1/8...been 1.140 sixty and have ran it to the 1/4 mile mark many time's when racing a 1/8 mile race on a 1/4 track with no issues !!

Travel is 5",but I'm at 1 1/2" now...Bills service is second to none !!

Also have a Dart with a Bobs Pro Fab frontend and it has 6" of travel...Seems to be a nice piece with front coilovers mounting to stock location on the top...It's a leafspring with caltracks smallblock car and I may like the extra travel !!
