Sinking Creek 4WD Association

Here are all the bars currently offered by Currie.


Length (in).....Diameter (in).................Kit
...35.75..............0.750..................Universal and TJ Front
...44.00..............0.800..................Universal
...32.00..............0.700..................Universal
...50.00..............0.900..................JK Rear 2 Door
...50.00..............1.000..................JK Rear 4 Door
...36.00..............0.750..................JK Front 2 and 4 Door

Per Currie, the 35.75" bar will be replaced by the 36" bar when the current inventory is sold out.

----------Arms----------------
Arms are offered in many configurations and each arm contains multiple holes for mounting the endlink. Some arms are straight for custom applications and there are some vehicle specific arms bent and shaped for use on certain Jeep models.

Straight Arms Available
Steel arms in lengths of 17", 18", and 20".
Aluminum arms in lengths of 18" and 20".

The holes in the arms are 1/2"


--------Bushings--------------
The universal bushings have an outer diameter of 1-???".

Here's some more tech to chew on. Lemme know if my numbers are off!

Tomorrow I will mod this spreadsheet to better reflect the actual working lengths of the bars and not the nominal lengths used in their identification by Currie. I may also add in some more effective arm lengths. <---This is done and reflected in the new chart!

If you look at the rate chart there are two very important things to point out. First is that the 32" and 36" bars are very similar. This is because they are the smallest diameters of the bunch and the diameter change between them is relatively small. Now, not only are these the softest of the bunch by a fair amount when you solely look at rates, but they are also going to be least effective at applying their rates at the wheel when mounted on an axle because they will be mounted farther inboard of the wheel centers than the longer bars. What this means is the 32" and 36" bars are going to be VERY soft when compared to the longer bars based on the fact that 1)their effective rates are softer and 2)because they are shorter their installation ratios will be lower.

So, if you're looking for a very small change and very little addition to roll-rate the 32" and 36" bars fit the bill. If you're looking for some real roll resistance then the 44" bar is the place to start. I think the 50" bars that are new for the JK show a whole lot of promise.

EDIT: I modded the chart to reflect more accurately the working length of the bars and added in more arm lengths to reflect the full range of arm adjustments.
