WS 3000
The Winner of the ADAC comparison test

The German Automobile Club ADAC reported in the Motorwelt 9/1998 edition on 4 tested stabilizers. The WS 3000 was the test winner with a positive total average rating of 1.8.

Showing the Caravan the way

Trailer stabilizers are designed to improve the tracking stability of caravans:
The ADAC tested four of them.

on the proving ground

Tests on the proving ground showed that the four stabilizers greatly improve tracking stability.

An unstable combination of car and caravan can cause anxious moments for a driver. Wrong reactions can really make things dicey.

Trailer stabilizers reduce instability and dangerous swerving to a degree - as earlier tests have already shown. Now the ADAC has tested four new stabilizers, all of which work on the same principle: friction used to reduce the trailer's tendency to sway.

AL-KO AKS: Requires somewhat more effort to operate

ORIMAT 2001

ORISMAT 2001: definitely more difficult to use

WESTFALIA SSK

WESTFALIA SSK: not exactly easy to use

WINTERHOFF WS 3000

WINTERHOFF: easy, handy operation

Three of the four devices tested transfer the frictional forces directly to the trailer ball on the towing vehicle through special couplings. The Orismat 2001 has rails on the left and right of the hitch which act upon the friction linings.
All four devices cost - if not included as standard - around  170.00 and earn an ADAC rating of "Recommended". All demonstrate good damping characteristics and thus contribute greatly to increasing the tracking stability. Only the Orismat and Winterhoff models were able to noticeably dampen pitching motions however.
