I finally said wth and got them. I have been told by several people that yes you can use xhd leafs OR the monos with successful results. Quick run down on my car: 67 Coronet, 470, 727 w/ 9.5" PTC (thank you Cope!), 4.10 Dana, 325x15x50 M/T drag radials, 90/10's front, stock rear shocks (I know, bad...) and xhd leafs, previous consistent 1.65 60's, best 1/4 of 11.80. I am sure I'll get the comment "use this or that rear shock" which is fine, but I'd like to know if there is a HUGE difference using the xhd's compared to the monos Caltrac offers. If I can hit low 11's next year (have done some head work, roller cam, 950 annular and other things) I'd do backflips. Thanks for your input everyone.

You really have to have their monoleafs. The Cal Trac bars do not work up to their potential with s multi leaf type spring.

For one with the heavy springs and those shocks you would be very disapointed with the resaults. you have absolutly no control and the caltracs would not work right. You need a shock that you can tighten up to control rap up. Using the heavy springs also makes it harder to control. Get the mono and their shocks.

If it were mine I would try the car without the cal tracs first and see how it does. Then put the cal tracs on it and try it...
I just pulled a set of cal tracs off of a Barracuda that I am building that had worn out SS springs.
Going with the XHD springs and nothing else.

How long have you had them leads on your car? Have they sagged on you at all? How is the ride hard?

Thanks for the replies here. I think I am going to put them on and see how things go. I'm also saving up for a decent pair of shocks as well... tax return!!  After having some trial runs with the set up next year, I'll determine if mono's are needed. Thanks again, Dave

If you already have the XHD's I would try them and see how it does...my car runs mid-low 12's and best 60 was 1.69 with a 4 speed and caltracs with 6 cyl multileafs something to keep in mind is that when caltracs first came out there were no caltrac monos, guys were using them with multileaf springs good luck

I have a set of Caltracs but I have to get leafs to work with my car. I have SS springs now but I can run a spring that will sag I will have tire clearance issues if it does. I think Caltracs makes a mono leaf with 1" extra height... It's a street car that I take to the tracks a few times a yr... Does anyone run mono leafs on the steeet?
i run the mono spring on the street,heavy 69 b-body w/6pt bar.7 years no sag yet.it does seem rough when you hit bbig bumps but what da hey ITS A HOT ROD!!!

I have Cal Trac's and Split Mono's on my car, and run it on the street all the time. It's a little harsh, but no big deal for me. The biggest difference for street use I noticed was the Aluminum bushings transfer alot more sound from the rear-end to the chassis. I run this setup with Summits adjustable drag race Shocks set at 40/60 (extra firm) out back and 90/10 up front.

I've run 1.60's w/ these XHD springs and drag radials, I just stepped up to Diff Dr axles and a set of cheap slapper bars. Looking for 1.55's or so. What is your current set up? Are you spinning? How are you aluching the car? What's the MPH at 11.80? I'm going to try the slapper bars before I shell out the cash for Cal-Tracks. Buddy of mine cut 1.50 60 foot times w/ a 590 cammed, E-headed 440, 4.56's, 318 leaf springs and traction bars. (11.0 car)
Keep us posted on how much they help...
The current rear set up is nothing special... just the xhd leafs and stock shocks, which is why I said I'm getting better ones next year. The last time I went to the track, my 60's were horrible (1.8x - 1.9x) but that was also before I did the recent work as mentioned in my first post. With my old set up (no head work, no roller, no carb, same m/t drag radials, same leafs/shocks) I was very consistent with 1.65 60's. The mph was 113 ish for the 11.80 time, that was before I realized jetting a carb gets the mph up there.
Bottom line is, yes, I had wheel spin off the line, foot brake launch at ~1800 rpm, M/T 325x15x50 drag radials set at 18 psi. My decision to purchase the caltracs came after talking to several people here who were at the track and watched how my car reacted off the line (fellow mopar guys here in town). It's a mixed bag of who runs what for rear suspension - either monos or leafs... which is why I thought I'd ask here to get yet another point of view.
Sorry for the long response, but I do appreciate the replies from everyone. Thanks.

It will be intresting to see how much you pick up. every tenth at the 60 foot is 2 down track. I'm running cheap gas-matic shocks not sure if they help or hurt.
