I'm guessing from your description that this is the recoil adjustment for the spring. plus will be stiff, and -minus will be mushy.

Adjust rear shocks, 1 - 5, which is stiffer?


Hi, Kevin if you're talking about the shocks on your dune buggy I can't help you, however if you are talking about your motorcycle shocks you're in luck, the setting that compresses the spring the most will be the stiffest. For more information about your issue please click on the links below. Good luck and have a nice day.

Tip

Susspension set up for Motorcross bikes


When I need to set up a motorcross bikes suspension I set all the settings (both rebound & compression) to the middle of the range on both the front suspension & the rear suspension

Now, measure the distance from the inside of the rear mudguard and the top of the rear tyre & note the distance.

Now repeat with the rider seated in position and note the difference,

This value should be 20mm. If not adjust rear spring pre-load to correct.

Now, measure the distance from the inside of the front mudguard and the top of the front tyre & note the distance.

Now repeat with the rider seated in position and note the difference,

This value should be 15mm. If not adjust front spring pre-load to correct.(if adjustable).

This gives you your starting point for the fine tuning with the dampening adjustments to suit the riders preferances.

On my ROAD bike could a Sram/Truvati XX or XO (crankset 42/28-cassette11/36) work smoothly with Sram red doubletap Thank you.


To use Sram Red Shifters with such a wide range rear cassette requires a Sram 10-speed MTB rear derailleur such as an XX or X.0, it will work without problems with your red shifter.

Because it is a road bike, i suggest leaving the road crankset and front derailleur in place. If you need low gearing I suggest a compact front crankset.

If you need to use a mtb crankset, attept to use the road front derailluer with it.

I'm having problem with my Toyota AE100 which when I drive, the rear suspension sounds like 'klak..klak'. For your info, I'm using a GAB adjustable suspension with 17 inch wheels. I'm trying to get rid of...


first of all, since you are using adjustable suspension you should make sure the spring is captive in the shock absorber. Lift the rear of the vehicle and support the car on the body, allowing the rear wheels to hang down. See if the spring can easily be moved. If it can. then likely the spring has sagged, or it is incorrect for the shock absorber. If not, while you are there check that the top hat of the strut is tight by lifting the wheel and strut assembly by hand. If you get any movement in the top of the strut, there will be a loud noise while going over bumps. Another area to check are the stabiliser arm/sway bar bushes. Mounted to the body you will see a bar that goes left to right, connecting to the struts with small link arms. Try to move this bar up and down against the body, paying attention to the rubber bushes where it meets the body. If there is movement in the bushes, there will be banging sounds when going over rough surfaces or bumps. Also check the small link arms for looseness or play.

is switch on?
The air suspension switch and bracket is mounted below the RH side of the instrument panel.

Dealer can run diagnostic test with scan tool for fault codes.
----------

The air suspension system is designed to improve ride, handling and general vehicle performance for static, on-road and off-road driving conditions:
  • Ride is improved by using an air type spring (the soft ride is inherent).
  • Handling is improved by maintaining constant vehicle attitude.
The system consists of unique rear air springs, the air compressor, air lines, air spring solenoids, height sensor, air suspension control module, attachments and associated signals derived from both driver and road inputs. With these components and signals, the air suspension control module commands changes in vehicle height that are necessary for the load leveling features.
The load leveling feature rear air suspension (RAS) systems shall automatically make adjustments in vehicle height so that the vehicle is always at trim height and constant front-to-rear vehicle attitudes are maintained over the expected load range of the vehicle. Adjustments in height that are necessary to correct height differences between the vehicle's left and right sides for the RAS system shall be restricted to what can be reliably achieved with one air suspension height sensor.
The system uses one air suspension height sensor, a steering sensor, generic electronic module (GEM) and other vehicle sensors to measure driver and road inputs. The system changes vehicle height using an air compressor, two air lines and the use of air springs with air spring solenoids.
The air suspension system holds vehicle height when the rear hatch or any door is opened. The system stores rear vehicle height the moment any open door is detected. The system then maintains this height regardless of the addition or removal of a load. The system will return to its commanded height when all doors are closed or the vehicle speed exceeds 16 km/h (10 mph).
------------------------------------
Air Spring
RAS vehicles use air springs in the rear. The air springs provide a varying spring rate proportional to the systems air pressure and volume. The air suspension system regulates the air pressure in each air spring by compressing and venting the system air. Increasing air pressure (compressing) raises the rear of the vehicle while decreasing air pressure (venting) lowers the rear of the vehicle. Vehicle height is maintained by the addition and removal of air in each air spring through an air spring solenoid installed in the upper spring cap and energized through the air suspension control module.
The two air springs support the conventional rear leaf coil springs.
Air Suspension Height Sensor
One air suspension height sensor is mounted on the vehicle. The air suspension height sensor sends a voltage signal to the air suspension control module. The output ranges from approximately 4.75 volts at minimum height (when the vehicle is low or in full jounce), to 0.25 volts at maximum height (when the vehicle is high or in full rebound). The air suspension height sensor has a useable range of 80 mm (3.2 in) compared to total suspension travel of 200-250 mm (8 to 10 in) at the wheel. Therefore, the air suspension height sensor is mounted to the suspension at a point where full rear suspension travel at the wheel is relative to 80 mm (3.2 in) of travel at the air suspension height sensor. The air suspension height sensor is attached between the No. 5 frame crossmember (upper socket) and the panhard rod (lower socket).
When the air suspension height sensor indicates that the rear of the vehicle is lower than trim under normal driving conditions, the air compressor will turn on and pump compressed air to the air springs. When the sensor indicates that the rear of the vehicle is raised above trim under normal driving conditions, this will cause the air to be vented from the air springs to lower the vehicle back to its trim height level.
Compressor Relay
The compressor relay is energized by the air suspension control module to allow high current to flow from the battery to the compressor motor.
  • A solid state relay is used in the air suspension system for air compressor control. The relay incorporates a custom power metal oxide semi-conductor field effect transistor (MOSFET) and ceramic hybrid circuitry. The relay switches high current loads in response to low power signals and is controlled by the logic of the air suspension control module.
Air Suspension Control Module
NOTE: The 4WAS air suspension control module is used for the RAS system. The internal processor recognizes external circuitry to determine if it is installed in a 4WAS or a RAS equipped vehicle.
NOTE: The air suspension control module is calibrated with information from the air suspension height sensor. A new or exchanged air suspension control module requires a ride height adjustment calibration process to be performed.
The air suspension control module controls the air compressor motor (through a solid state relay), and the air spring solenoids. The air suspension control module also provides power to the air suspension height sensor. The air suspension control module controls vehicle height adjustments by monitoring the air suspension height sensor, vehicle speed, a steering sensor, acceleration input, the door ajar signal, transfer case signals, and the brake pedal position (BPP) switch. The air suspension control module also conducts all fail-safe and diagnostic strategies and contains self-test and communication software for testing the vehicle and related components.
The air suspension control module monitors and controls the air suspension system through a 32-pin two-way connector. The air suspension control module is keyed so that the air suspension control module cannot be plugged into an incorrect harness. There are two sides of the harness connection to the air suspension control module. Each is uniquely colored and keyed to prevent reversing the connections.
