Rear suspension tends to 'tramp' (hop up and down) when large amounts of torque are applied. If you have a more powerful than stock engine, to counteract this, you can fit anti-tramp rods a.k.a. Traction Bars.

Overview

The traction bar stops the wind-up of the spring.

The Datsun Comp setup is for a dedicated track car:

Slapper Bars

The famous Lakewood traction bar:

The traditional street/track setup is like this:

'Slapper Bar' Street/Dragstrip Setup This is like the other photos, except the front is not solidly mounted to the chassis. It doesn't interfere with normal suspension unless wind-up occurs. Plus it has a little "play" so that it hits, it slaps, bites down to help traction.

Anti-Tramp Bars

This commercially designed anti-tramp system is similar to the Datsun Comp design.
