traction bars and j bolts


Search and could not find an answer.

Just got my axles back from the shop and went to install. On the axle tube end of the J bolts, is the upper nut (inside the bracket of the perch) required?

The bars are the lakewood/comp engineering style.

The reason I ask is once the J bolts are in, there is no way to turn the upper nut to adjust. I was wondering how this affect the total torque value of the lower nut that tightens the entire assembly.

Depending on the angle of the front of the traction bar,, wouldn't it allow the rear portion of the J bolt to rotate slightly and affect the tightness of the set up?

I had movement in the passenger side that destroyed the pads and wore the axle tube.

Thanks in advance

I removed my rubber pads and added a steel plate of the same size to compensate for the rubber thickness.

Rubber pads will allow movement....bad.

Re: traction bars and j bolts

Yes, replace rubber with alum/steel spacers.
Then use a nut on J-bolt for clamping with retaining plate nut for clamping.
Then use nuts out on J-bolt for adjusting height/distance from pad to bottom of spring eye.
If pad does NOT hit spring eye, the bars WILL bend the spring over time.
