how much more of a lift could u accomplish with these bars as compared to stock, do u get a extra inch or maybe more?...infor wouild help, cuz i need to lift up just the front of my f1fiddy, i got the rear already taken care of.

 

powerdome, Both the 4x4 shop that did most of my work and I beleieved that the heavy duty bars gave an extra 3 plus inches of lift over the stock bars. We didn't use that much, but we cranked them all the way just to see. Just watch the angles on your cv axles. Hope this helps. Steve

 

Well I got my Heavy Duty bars installed yesterday and after cranking them up they have leveled the truck out which gave maybe 2 inches of lift in the front If someone has the stock measurement from say the ground to a point on the bumper I could measure mine and we could see how much lift I really did get. I havea 97 F150 with offroad package we need to compare apples to apples here. I only have at the most two threads left showing on the adj bolts so maybe if they got turned in all the way I could possibly get another 1/2" but i would say and that is more than likely wishfull thinking on my part.

is that 3" over stock ride height? or is that 3" over what the existing torsion bars max out at?...cuz if its only 3" over stock, im sittin close to that rite now.

 

3" over stock

Richard D.

 

Just a question, i never measured my lift in the front, but what do the stock bars max out at?

 

Her is what I have discovered with the heavy duty basr they may lift the truck a tad bit moree than the stock bars but not by much the biggest differance I have noticed is that when going over very large dips in the road before the bars the truck would bob up and down maybe twice whereas now there is no rebound at all that I can tell it has made the front less prone to sway and rebound up and down.I just had them installed yesterday but I havea set of RR tracks that I have to drive oever everyday and before the bars my truck would really go down then back up fast and then take as econd to settle and now it does not hardly move over the tracks.

Does the Screw have an optional 7700lb front end with the heavy duty torsion bars? And your getting 3" of lift!! I have thought about putting a add-a-leaf in the rear, but do not want it to nose dive to much. I have adjusted my torsion bars 1" already. If these give that much lift I might put them in and an add-a-leaf in the rear.

 

I have no clue about what the SCrew has I have a 97 Supercab Short bed. As for 3" of lift I DO NOT think it is that much if someone took some detailed measurements and gave them to me I could take the same measurements and see what amount of lift they provided they are not going to give anymore than the stocks ones I don't think but again I can not be sure about that. My truck does not appear visually to sit much higher than it did prior to hyaving them installed but then again it sure does not look nose low anymore. AZ how are you fitting 315's without a lift or do you have a lift?

Richard D.

 

AZSCREW, We measured my Expy with the old bars cranked all the way up and then again with the heavy duty ones, and the result was just over 3 inches more vertical movement. Now, my CV axles were definitely at a pretty good angle, and I didn't want that. Also, I would have needed to put 2 inch spacers in the rear springs to bring the back up to match the front end. I imagine the amount of travel with full crank will be pretty similar to the Expy for you. I'd be curious to see if Richard actually cranked them all the way up? As far as I know through the dealership, you can only get the 7700lb bars (4150 lb front end) with the snow plow package, but it's worth asking your particular dealer if they'd do it for you. some dealers are pretty reasonable about this, especially since there is no real difference in cost! Steve

 

Well I had my bars cranked almost all the way and let me tell you DO NOT do it I discovered a problem last night while under the truck to check something else out. What I discovered is that with the bars cranked up that much 1. the CV angles are to severe 2. My tire was rubbing the sidewall on a part of the lower control arm that sticks out when turning to full lock right or left. I discovered this becuase I had this big black line on the sidewall of the tire. Now I am only running LT285/75/16's so for someone running an even larger tire I will almost guarntee this is going to be a problem and not one that you will feel or hear when driving I didn't. It will eventually wear away enough sidewall material that you could get a blowout. I am going to take a frw pituires of what it was rubbing on and post them in my gallery someitme next week probably. The little area it was rubbing on I honestly thought about grinding off I am not sure it really serves a purpose. It is just a **** that sticks off of the front of the lower control arm.

Richard D.

 

Rediculous,

the CV's on my truck handle fine, and I run 17" of travel in the front, of course this has to do with new suspension & steering (coils, control arms...) see gallery.

Further, the only thing cranking the torsion bars does is increase spring preload, and as a result decreases sag. The wheels total travel and axis remains the same. So, if your tire rubs, it would rub with the torsion bars cranked, loosened, off, whatever.

The statement was best legitimized by your statement about grinding unknown parts on your truck (?), and the fact that you "had" your torsion bars cranked.
Dude, it is two bolts, I feel you may need to be a little more hands on before screaming that the sky is falling

 

Well Weezel I have 20 years of working on vehicle so you have no clue as to my hands on experiance. And as you yourself said you have a lift which took care of the CV angle nimrod. Cranking the torsion bars does raise the suspension just as though you had stuck a jack under it to lift the front end. So again you made a statement that is incorrect. As far as the grinding the piece off I did not call it by it's name becasue all it is a a piece of the lower control arm that protrudes so you basically need to shut your trap becasue you have no way of even knowing about what I am refering to get under yourt truck and you will see the piece in question. No one was screaming that the sky was falling I am simply pointing out a warning for something I have discovered since Cranking the torsion bars on my truck which did in fact lift the front end higher thus increasing the angles on the CV joints. So you dont think that when you jack the truck up your CV angles change HMMMMMM maybe you are the one that needs some more hands on time not me. Nice way to attack someone you know nothing about D***Head. And one more thing the piece I "THOUGHT" about grinding off I decided after looking at it closer that it may in fact actually be a part of the structual reinforcement for the lower control arm so I decided it was not a good idea . Maybe you should read things a bit better. And stop attacking people for your own ineptness.

sour?

I stand behind what I stated. I have two f-150's, one is a race truck, that is the one with the replaced susp components (coils). The other is a 2001 f-150 King Ranch screw 4x4(torsion bars) both use the stock cv's, the KR is fine, no rub, bub. The tires on it are 16.5"x33"x12.5" on 4.675" offset.
I suggest your tires may rub due to an offset, or width of tire problem, I will not waste my time extracting exact numbers regarding deflection of the driveline (CV's) to defend myself against your tirade. The reason I brought up the long travel rig is that it uses larger wheels 35" BFG bajas(more stress) more driveline deflection (142% increase from stock) The engine pushes in the neighborhood of 400 hp and with the 4.88's it transmits more torque to the CV's than most. Consistantly the stock cv's have handled the punishment well. My truck and others in the same circles use these cv's with nary a prob. bob.

Again, the adjustment of torsion bars (increasing/decreasing preload)does not change front wheel travel. Yes, you increase Preload, as a result the static, unsprung weight has less of a sag effect on the truck, yes the deflection on the cv's are increased, but that does not change the fact it has NOTHING to do with your tire rubbing.

However, that temper of yours will only lead you to a early grave.
Yell on, friend.


bye the way, I like the screenname you chose; it seems fitting. Richard D***head

If any choose to see for themselves, I will be at the las vegas Supercross next week, and the Baja 500, May 20 through June 03.
Look for "the Familie/thq" action sports marketing group vehicles in the pits

 

First of all I was not even close to yelling and I am not sour, you are the one that attcked me first for absolutely no reason what so ever. Another thing I never said anything about the tosion bars increasing or decreasing the amount of travel the front suspension has or doesn't have. as for my tires rubbing they did not rub prior to me raiseing the truck via "CRANKING" the torsion bars which is why I mentioned this to begin with. Did you understand that I HAD NO RUBBING PRIOR TO. Also I suggest you go out to your truck and see where the tires are at full right and left turn the jack up the truck just enough so that the wheels are not going to leave the ground then turn you whhel again and if you are smart enought ot pay attention you will see that the tires do end up closer to other suspension componet than when sitting at stock and the same would also apply if the suspension was at full compression. And since you are in Racing like you say you should be well aware of that yourself. When cranking the torsion bars it essentially raised the truck thus extending the suspension componets. Go egt your self a tape measure and measure the bumper heigth prior to cranking them and then after cranking them when I did mine I got just about 3" of lift from that. I will be picking up some film later today and posting the pictures of exactly what was hitting so you may see for yourself.And I will say it again so you understand I HAD NO RUBBING PRIOR TO CRANKING THE TORSION BARS. Was that plain enough for you?

And just so you know I am not a D***head I am the a A**hole
Your screen name fits you even better becasue after all you are a little freakin weazel
