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

Overview
The traction bar stops the wind-up of the spring.
If your skids marks are pulsating, you risk breaking an axle
[edit]
Anti-tramp Springs
Custom anti-tramp springs developed and made by John Taylor at Pedders Penrith
[edit]
Datsun Competition
The Datsun Comp setup is for a dedicated track car.
[edit]
Coops
Coops used extra-long lowering blocks for a mild anti-tramp effect on a 9-bolt M78 rear end

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

Slapper Bars
The famous Lakewood traction bar:
The traditional street/track setup is like this:
'Slapper Bar' Street/Dragstrip Setup
Slapper Bars are like the Caltracs & Datsun Comp setup, 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.
Not difficult to make yourself: 1-3/4" square tubing, Hyundai H100 tray stops. Custom U-Clamps. Double nuts or locknuts on all u-clamps for extra security. These had a big difference at the rear when launching and take off!
[edit]
CalTracs
CalTracs are the most innovative traction bar units today, often imitated, but never duplicated. Calvert Racing manufactures and distributes the world famous Caltracs traction bars.
