BUSHING PULL BAR (TORQUE LINK)
This torque link uses energy absorbing polyurethane bushings to absorb engine torque and increase traction to rear tires.
1. Engine Torque Bushing – Torque link comes standard with two blue (80 durometer) poly bushings on the engine torque side.
This durometer works well for a majority of racers, especially those running open class mods such as UMP and USMTS cars. IMCA
mods, or cars with less spoiler or motor may need softer bushings. Keep in mind, when adjusting engine torque bushing preload
on this unit, brake bushing preload is also adjusted. If engine bushing preload is increased, preload on the brake bushing side
is also increased. This may effect corner entry (brakes) and corner exit (traction) of car. A general starting point is 0 to 1/2 turn of
bushing preload on nut (A).
Note: Bushings with a lower durometer rating are softer, higher durometer rating bushings are harder.
2. Brake Bushing – A single red (87 durometer) poly bushing is standard with this unit but other bushings may be substituted.
Harder brake bushing(s) or more pre-load will tighten the car on corner entry, softer brake bushing(s) will loosen or free the car on
corner entry. A general starting point is 0 to 1/2 turn of bushing preload on nut (A).
Note: Bushings with a lower durometer rating are softer, higher durometer rating bushings are harder.
3. Travel Indicators – Travel indicators should be pushed against rear bushing plate before each test session or race when select-
ing bushings or making adjustments.
4. Torque Link Maintenance – Periodically lube torque link at the grease fittings, only a few pumps are needed. Continually check
bushing free height as they will change.
