I was talking to a chasis shop down the road from my place and filled him in on my slick spinning problem. He suggested removing the rubber snubber (he said thats for street) and installing an aluminum biscuit preloaded right against the spring. What do you guys think?

That is a hard rubber bushing. Have you ever trimmed them? Have you ever set the pre-load and fooled with the bar adjustments? Automatics do not like to have slapper bars pre-loaded hard.

When my car had the slapper bars, I had to have between about 1/2" of space between the snubber and the spring. When I tried closing the gap to zero it spun like crazy. It seemed to lift the body rather than plant the tires.

Mike,
Was that with your big-blocked, 4-speeded, Torino?

It seems to me that if the body was lifting, then there should of been more pressure on the axle, right?

Hey Ryan,

Yeah it's the Torino I'm talking about. I'm not much of an expert on suspension, but I did experiment with the traction bar gap quite a bit when had them.

I tried it (closed gap) on my car on two different occasions a few years apart, just to make sure of whether or not it would work for me. Both times it acted the same way.

I can't really explain the reasons why, but I can tell you what it felt like. It felt like the rear of the car was lifting more than usual immediately and the tires would just break loose upon acceleration.

It's almost like the traction bar had too much leverage with no gap. I could be way off base, but my guesstimation is you probably do want to have the body and the rearend go in seperate directions, but given a choice, I'd rather have the rearend go down as apposed to body go up. With a gap the rearend seemed to go down more and with no gap the body seemed to go up more. It probably has to do with leverage and timing.

I'm sure this varies greatly from one car to another. Maybe somebody else would know why it didn't work better than me.

I always thought on "slapper bars", they planted the tire by shocking it when the bar contacted the leaf spring. And the further the distance before contact, the harder the shock.

Was I way wrong?

I always ran my slappers on my 70 about 1/2" away from the spring.

do those Aluminum biscuits go good with southern muscidine jelly? I used to run about 2 inches space in my slapper bars and I did replace the rubber with a grade 8 bolt, but the bolt landed on the front spring eye and it made a loud noise when it hit. I couldn't tell any difference between those and the rubber so i put the rubber back on.

Alex, were you hinting that stick-cars DO LIKE to have slapper bars pre-loaded hard?

Although not true slapper bars, but for conversations' sake, I believe SSM and Cal-Tracs recommend that their bars be cinched up tight with some pre-load (no air gap); However, I'm not recalling if they have different amounts of adjustment recommendations for Autos vs. sticks...

Come on, Captain Alex - tell us young'ns what YOU'D recommend for an air gap or amount of pre-load for our old leaf spring cars with:

1) slapper bars: Auto vs. Stick

2) SSM bars: Auto vs. Stick

3) Cal-Trac bars: Auto vs. Stick

4) Slide-a-Links: Auto vs. Stick

OK -- Forget the SSM bars.....

Let's hear about cheapo slappers, Slide-a-Links or Cal-Tracs and the different adjustments necessary for Autos vs. Stick cars?

Slapper bars need about 1/2 inch gap on both sides with a stick.
3/4 on the left and 1 inch on the right for automatics.

....Am I in the midst of a M&M "Burn-Down" with Capt. Alex?

-- How long will he wait before he pulls into the Forum 'Staging Eyes'?

-- How long before he'll finally sprinkle a few "tid-bits of verbal assistance" down onto us 'undeserving underlings' who are so very hungry & crave for his "table scrapings of national record-holding FoMoCo racing knowledge"?

I...don't know...how...much...
..longer...I...can...hold....out...Aghhh.

Cal-Tracks with a stick. Center hole and prox. 1/8 pre-load as a very good starting point. Will work in 90%.
IN auto, bottom hole with no pre-load. Check side clearance between bracket and bushings in all installations. I have found most problems attributed to bracket binding.

SteveW, Not only did he (Alex) get me off the line by clicking a .501 light, he and his Bad A** '65 smoked me at the big end BIG TIME!!!

Alex,
I bow before you O' Great Hole Shot King!

Seriously though - Thank you once again Sir for sharing your race-proven experience and knowledge!

I wish for you this Thursday - Killer lights, lightning reflexes, and that the only breakage occurs in the OTHER lane!

Whoa Now!! What are you saying, SteveW ????
-- Are you saying that Alex RED-LIGHTED?! (bottom bulb) Which resulted in him "unloading pre-maturely" with trigger finger launch?!?

Looking at too many ladder bar set ups and Cal-Track kits still in the box. LOL
Lower hole for autos and upper for sticks.

PS, there is another hole at the top too you know Mike!
