I'm driving a 2000 larkins chassis with the medium length swing arm suspension the car works good except when I get the car into the turn it feels like the left rear is light and I can't get on the gas till I get it out of the turn.I've got 57.5 rear weight 51.5 left side and 200 lbs. of bite in the car,It has a 850 RF & 700 LF,225 rear springs, If i soften the right rear it really does it.tried stiffer right rear still did it 250 lb. Anyone with a larkins have simular trouble?Any suggestions?

It might be kind of hard getting in touch with Larkins since they have been bought out. Last I heard someone had bought the jigs and shop equipment. Here are just some suggestions, take them for what you will. Put the left rear swingarm in the top hole. Maybe take some bite out of the car. When I ran 200# of bite the car was loose getting in and a little to tight coming off the turns. Because when you are braking and in the middle of the turns, the left rear has more effect on the way the car turns making the car want to pivot on the left rear. That will make the car loose getting in and in the middle of the turn. Try running 120#. Also, when you hang weight on the car, be sure to hang it high on the chassis this will tighten the car up, too. When you hang it low on the undersling it will want to push the rearend of the chassis out, instead of when you mount it high, this will give the car more body roll on the right rear and tighten the car up in the middle. Remember that right rear will tighten the car up getting in the turns and in the middle. Left rear tightens the car up coming off the turns. Just my two cents worth.

just somthing to look at also, does the car have sliders? if so is it extending to full? and or is the rear hitting the underslung? I had to lower the underslung on the lr to keep it from tring to pull the lr up in the turns.

Mod7 thanks for the feedback, my weight is high and to the right and my swingarm is in the top hole.The car isn't loose on entry or in the center but when I try to get back on the gas the tires break loose so i pedal it till i feel it get a good bite.would a J bar or short panhard bar help let it settle down faster on the left rear ?has a long panhard bar now with about 5 degrees in it.The problem with this car is it only does this when it's tacky or wet works great on dry slick so I'm having problem qualifying have to run the b most weeks to get to the a usually ends up faster by the end of the a.

dirt racer 14 thanks for the feedback.I looked at hte left rear underslung and noticed its got a dent under the rearend I think I'll add a drop to theleft rear to see if it helps because the car owner said the car really lifts when I get on the gas maybe its pullin the left rear up huh?thanks for the suggestion!!

If you are getting alot of body roll on the right rear, or the car lifts alot during acceleration in the middle of the turns, I would check the undersling on the left rear and make sure it's not pulling the left rear up off the ground. Alot of cars do this and people can't figure it out. Might try to install a new left rear undersling and bend it down a inch or two. The short panhard bar will cause more lift in the middle and off the turns. It will definently tighten the car up, but I just don't think this will fix your problem. Like dirtracer14 said, I think that your problem may be with the undersling lifting the rearend up and loosing traction there. You could try raising the panhard bar, so you don't get as much body roll, but then you might have to change the setup all together to compensate. How much body roll are you getting on the right rear now?

Mod7,The right rear gets about 3inches of travel.The cars doesn't have sliders it has weight jacks.Also it has a 22 gallon fuel cell mounted fairly close to the deck.the pullbar is mounted in the center of the rear track.Uses a 700 lb. pull bar spring.the left rear rail lifting the left rear tire up make sense because the car doesn't do it when the tracks slower and drier and doesn't have as much sideways force.thanks again mod7

IF THE CAR IS ONLY DOING ON TACKY OR WET YOU MAY WANT TO TRY A STIFFER RIGHT FRONT SPRING. ON A HEAVY TRACK THE CAR WILL TEND TO FALL OVER ON THE RIGHT FRONT MORE BECAUSE OF THE INCREASED SPEED GOING INTO THE CORNER. IF THE RIGHT FRONT IS TO SOFT IT WILL TEMPORARILY UNLOAD THE LR.
