Hopping off the line

Re: Hopping off the line

the battlebar clamps to the front of the leaf itself....whereas the caltracs actually mount @ the front spring hanger. chris and i talked about this when i bought mine from him. he did not recommend them with fiberglass springs as you can actually crush the fiberglass springs by tightening the front battlebar bracket... causing a weak place for the fiberglass to break.

If that's the case, there should be a torque spec that will secure the battle bar, but not damage the fiberglass spring, no?

i guess chris can clarify wether or not that will work... i do know that when i contacted him asking questions about his bars he did'nt recommend the fiberglass spring.

I certainly hope that there is a solution. I keep hearing of the battle bars performing better than the cal tracs, but with a potential weight savings of many pounds with the Flex-a-forms, I just can't imagine going with something that will force me to stay with stock springs...

I'm with him ^^^^^ ---

Re: Hopping off the line

flex-o-forms do not work with battlebars.....i believe they are mounted differently.....i was planning on doing caltracs and fiberglass springs, but i see alot of fast trucks on stock leafs, and the $400 might be better somewhere else

i will be in for a GP if the price is right

Re: Hopping off the line

If some have experienced the hopping off the line, I was wondering what could be done to keep the tires planted. I just got my Nitto drag radials to replace the 4 year old Yoko's AVS ES 100's. The suspension I haven't touched since I have owned it for the last 4 years. I guess I will try the drag radials to see if that helps, if not, looks like this year will be suspension work.

....a couple of things come to mind:
1. Battlebars (Im not knowlegeable on), Caltracs (of which I have, with fiberglass springs),
or ladder bars work to cure wheel hopping/axle wrap during acceleration

2. Shocks are a key component as well (if yours is worn, or if your using the Ty
air suspension factory setup, this probably hinders a bit)

3. Nitto Tire pressure (a setting below 15psi is not recommended), and while
Nittos are a harder compound (and thus last longer) too much burnout actually
overheats the tires and creates as much problems as too little burnout/heating.
(I think temps are suppose to be arount 120 degrees, but dont quote me on this).

4. Pinion angle also can be a factor (if you have lowering excessive). As
can be weak springs.

5. Lastly, if you have fiberglass springs, while they are lighter, it is critical that
you torque them properly (or you can crack/damage them causing breakage).
Also, heat damages them if your exhaust touches or rests on them). There
are differing opinions as to using lowering blocks with fiberglass springs
(ie whether they entice breakage or not). Even placement of the "angled shim"
could make a difference. And of course, every spring has a spring rate
which varies from soft to hard (affecting rebound rate).

You didn't comment on whether you had a rear sway bar or not; or whether
you had stereo equipment or extra weight in the rear (Im assuming not).

Hope this helps a bit...
Let us know how you like the Nittos, as some like them for their
wear rate (and moderate traction on the strip, with better than average street traction)
and others say the 6/32 tread (and not the compound) in rain causes hydroplaning.
While not as bad as slicks or M/Ts, BFG, or Hoosiers, having the rears and fronts
"twirl ya" can be alarming in a downpour. If you were on the Power Tour, there
were many instances of this

...oops I forgot to add the obvious, to check your posi rear end as it may/may not be going out as well.

Re: Hopping off the line

The BattleBars solved my axle-wrap and wheel hop issues immediately. One of the best mods I've ever done to my truck, period. The truck stays planted now and I cut a 1.6 60' last night at the track without setting any preload on the bars before racing; I left some play in them (1/4" gap) so the ride wouldn't be too stiff driving to the track. They are a great investment :tup:

Re: Hopping off the line

Just wondering what were your 1/4 mile times?

Re: Hopping off the line

I never ran at the track without traction bars so I can't give you before/after comparisons, but I noticed right away how much more planted my truck was under boosted launches. It used to get all squirly and often have nasty wheel hop...felt like the rear end was going to fall out. With the BattleBars, the truck stays level and straight with 15+ psi off the line and the worst that will happen is a four-wheel burnout. Funny, your sig says 12.3@107 on stock motor and that's essentially what I got last night at the track. Have no doubt I'll be able to get 11s out of it with a few more tweaks, though. The traction bars and solid mounts are great mods that really help put the power to the ground.

Larry, I put them on a week ago. I only drove it home. I can tell you when I am turning and the turbo spools, the back end doesn't step out anymore. The real test will be April 21st, a bunch of us board members are going to Tri State near Dayton OH to race. That will be the real test.
