Which need to be lenghthened first?

[maddzz1]

When adding lift to your jeep which need to be lengthened first, the upper cotrol arms or the lowers? At about what height do you need to go from stock to adjustable? for uppers and lowers ?

[CWLONGSHOT]

Lowers first but that depends on the height of your lift.

 

A couple two inches can get by with factories.

 

At three inches you need to look into longer lowers.

 

At four both are useful and adjustable getting to be a necessity.

 

At 5-6" you need to look at lots stuff. Steering, possible longer drive shafts, Long Arms or Drop Brackets and def Adj. control arms TOP and BOTTOM.

Man you learn something every day! I just wish it would quit adding to the "to buy" list. I've been running 4" with the stock UCAs, LCAs, and trackbar... what exactly is the problem... I got the thing with 3" on it so I don't really have much of a comparison.

Stock arms with that much lift negates all your caster and also pulls the tires back towards the rear of the wheel well. And a stock track bar will pull the axle sideways under the truck (not to mention that a stock track bar doesn't really like that much operating angle).

How would these work...

LCAs:

I noticed that they didn't specificaly advertise that they were made to compensate for a lift, just that they're adjustable... :???:

They will work...BUT, the control arm design is one that will be a bit more harsh and not as flexible. The factory CA's flex pretty easily because they are made of light metal. They isolate and also flex a but thru the rubber bushings they have at either end. These you selected will allow you to get your caster back, but because of the poly bushings and rigid design, won't flex. Under extreme articulation put ALOT of stress of the brackets.

 

My personal choice for CA's are the JKS brand.

The TB will allow you to center your axle after the lift but, Like Pete mantioned, the TRE end is also a limiting factor in overall flex. the TRE only has so much range of motion. BEST case is that you mount is absolutely square to the ground. This is not possible as your lift grows. as it grows it points to the axle taking away from the amount of droop it can give you. Understand?

 

My preference, Again I choose the JKS brand. I have this on my TJ.

For even better flex, I prefer the WJ style conversion. Kevin's makes a conversion to this style bushing. JKS makes the bar for them and they modify a factory mount to make it work. This is whats on my MJ. Its not cheap, but you can recoup $50 if you send them your old frame side, TB bracket.

Good luck, hope this was helpful,

i also have the jks tracbar and UCA's. i would deffinetly recommend them no problems yet and articualtion is almost unlimited

Wow, why haven't I heard of these guys before? A bit expensive maybe, but looks to be worth it, thanks :cheers:

I have the RE adjustables on the TJ but have been looking at JKS ones for the MJ. They seem alot easier to adjust.
