Post Re: -06 torsion bars,keys,bolts or something else different than -03 ?

thanks for a good information

what I´ve been told
if I crank my stock keys to archieve +2" lift or buy these aftermarket keys same result: stiffer ride (if used without cognito kit) .

I might not need aftermarket keys with cognito kit if I can crank my stock keys to archieve lift I want right?


"Maxx Cam 2 can lift the front of your truck up to 3-full inches or lower it 2.5-inches with virtually no loss of ride quality"

"ReadyLift® keys are guaranteed never to affect the OEM ride and will not add more pressure on the stock suspension components."

It seems that no one can tell me will cognito kit work with ranchos lift I´ve send various email to ranchosuspension, cognitomotorsports, trailduty just to name few still after week no answer yet...

Yes, but the stiffer ride is caused by the fact that the shocks and upper control arms bottom out to soon. And even if the correct replacement shocks are not bottoming out any more, the factory upper control arm is still bottoming out on the bump-stop way too soon, this is what is giving you that stiff harsh ride

Right!

Not true, because the UCA is still bottoming out on the bump-stop way too soon.

This really is only half true, but cranking the torsion bars will not add more pressure on the stock suspension.

You might try a phone call. The person you need to talk to at Trail Duty is Phil. Toll Free (in the US): 888 711 5908 - Tel: 361 288 2466 - Fax: 361 288 2196

Might just be a whopping phone bill from Finland though!!!

got mail from Phil and Cognito works with ranchos lift.

Both cognito kits works: upper control arm ball joint desing and stronger choise would be uniball upper control arms..

I´m just thinking is the uniball desing worth 220$ The ball joint isn´t the weakest point of front supension I think..

Thanks a lot

Hammer, if you do any serious off-roading in Finland then you should know that the real weak link of the H2's front steering components are the tie rods.

Check out <THIS VIDEO CLIP> to see why.

Anyone into serious off roading should replace the OEM tie rods with the <Fabtech Tie Rods>.

Good luck with your project!
