has any one relocated there rear shocks to a more vertical position for better reaction on launch.this was recomended to me ,just wanted to get an opinion on this.i'll be running caltracs bars and split leafs with a 4 speed.
This entails moving the rear shocks behind the housing. Typically, you have to fabricate or purchase an upper mounting bar which welds between the frame rails and lower mounting brackets that weld to the rear end housing. How much power are you looking to make? Something like this is not really necessary unless you are making VERY serious power.
it will probably be in the 350-360 rwhp.i was wondering if this mod was really needed.the only problems i've heard of is breaking the stud off the bottom of the shock.when there is to much drop in the rear on launch
just use some gussets to stiffen the existing mounting locations.. i was thinking of doing that to mine.. just added insurance i suppose
rs5000 is a good one so i hear.. i am running air shocks... yeah.. gotta change that before race track opens
Not necessary at your horsepower range. The Rancho units seem to be the ones recommended by Calvert. I believe that Simon is right on the part number. I'd have to check it to be sure.
If I remember correctly Steven Moore (Cometgt1974) Welded a new crossmember between his stock rear frame rails and mounted his shocks strait up and down but slightly forward at the top. With Both shocks Behind the rear axle.
I used the OEM shock mounts and positioning, but reinforced the upper mounts and removed all of the rubber isolators from the shock....and used spacers & washers to take up the space. You want to remove most, if not all, of the deflection so that the shocks can do their job..no matter where they're positioned. It helps...more so on a rough track or a car that has a tendancy to wheel hop.
The Rancho's Calvert sold me for my 72 are part number RS99113. They are the adjustable RS9000x series.
