Lakewood `J Bolt`slapper bars

Hi Rory,

If that slapper bar doesn't reach and contact the spring under the spring eye, it will bend your spring....

The old trick was to extend the length of the bar so that the snubber contacted the spring eye.....

You can adjust the preload by changing the height of the snubber.....

Jack up the car by the body and change the length...

If it is still too far away, you can add pinion angle shims between the bottom of the spring and the slapper bar spring perch.....

If you can find the "J" bolts you should run them to spread out the load of lifting your car away from the spring perch (that's a lot of leverage on those welds)....

Also put the stiffest extension shock that you can find on the rear...

They work,
Bob
