How To Adjust Torsion Bars


When your car is way too tight or way too loose, you have to fix it! The same thing happens with vehicle torsion bars. A torsion bar is an internal component of the suspension system that helps keep your wheels from lifting off the ground when there’s a bumpy road.

If a torsion bar becomes twisted or broken, your car will be more likely to bounce instead of settle down under heavy stress. This can cause damage to the car frame, engine, or both!

This article will go into detail about how to adjust a front or rear torsion bar for better performance. You will also learn some basic tips like why timing a bar replacement is important.

Adjusting Vehicle Suspension Systems

To fully understand how to adjust a torsion bar, you first need to know what one looks like. Picture yourself standing next to a tall ladder. Now, climb up this ladder as quickly as possible while keeping your feet parallel to the floor.

When you reach the top rung, pull upward firmly but gently until the ladder collapses. That is what a torsion bar does! It gives your wheel vertical lift in order to roll over small bumps.

Make sure the bar is not too loose

The next thing you should check is if your t-bar bar is too tight or too loose. If it is too loose, then push it in more with pliers or hand tools until it feels comfortable.

If it is too tight, then take off pressure by either loosening or removing the control arm bushings or plugs, remove any corkies (rubber bushing) located between the torsion bar and the inner wheel fork, or cut away some of the excess clamping force using screwdrivers or hammers.

Make sure the bar is not too tight

Once you have determined that your t-bar needs adjusting, then you must make sure that it is not too tight! If the bars are way too close together, your feet will get stuck in between them when walking, or you may even injure yourself by stepping on one foot and getting poked by the other side!

The opposite problem occurs if the t-bars are too tall. Now you do not have enough room to move the leg up and down, which can cause pain or injury later on. This could be due to weight lifting with short legs, or just because you got taller as you got older.

When trying on shoes look at how much space there is under the ball of the foot. You want to make sure they fit properly and that there is enough room for normal movement.

Lower the handlebars

One of the trickier things to do is lower your t-bar or handlebars. This will cause your front wheel to rise higher, as there are now less levers that help push it down. You can lower them just by loosening all bolts and nuts, then lowering them slowly.

The easiest way to do this is with tranny mounts. These go along the side of the fork, and have threaded holes for rods to connect onto. Simply loosen these, and you can slide the bar up or down easily.

For more difficult bars, use wrenches to remove clamps, or undoable screws. If possible, find out what tool can be used to take off the screw, and use that instead!

Once they’re both loose enough, you can pull one apart and move it closer to the other, or even tip one away from the other so that the bar sags in opposite directions.

Lower the seatpost

There is nothing wrong with tiring of your current set up, which can sometimes make it hard to find a good deal on a new bike. If you are looking to save some money, then this article will help!

Bikes come with pre-installed torsion bars already! This is usually only one bar per side, but if yours have two then this article will show you how to adjust them.

By lowering the height of the handlebars, you give yourself more room to maneuver the bike. More space means better control for tricky situations or even track days!

Lowering the saddle height also gives you lower feet, which may be easier to ride than having high ones.

Tighten the seatstays

When wheels are not spinning freely, it is usually because of tension in one or more of your car’s torsion bars. These are typically made of steel and are attached to the inner wheel carrier that connects the hub bearing to the rim.

By moving the lower control arm forward or back, you can loosen up these torsion bars so your wheels spin more easily. To do this, use a pair of heavy duty vice grips to pull apart the two ends of the bar. Now push them together slightly harder than when you took them out!

This will relax the tension on the bar enough so that you can then roll the other end into place using the handle of a screwdriver or hex key. If needed, repeat this process until the bar is completely loose. You may have to do this several times before all the slack is removed.

Once done, re-tighten each torsion bar by using the screws provided for that job.

Check the brakes

The first thing you should do if your t-bar does not feel very firm or does not seem to be working properly is check your brake pads and shoes!

If your brake system has hydraulic fluid, then make sure that there are no leaks coming from anywhere in the lines or out of any seals. If it’s mechanical, make sure they work by stepping on the pedal and noticing if the wheels slow down.

You can also test the strength of your wheel rims by dropping a heavy object onto the tire – makes sure they hold up under pressure!

Another cause for poor performance is bad rotational friction due to dirty components.

Check the tires

The first thing you should do if your t-bar is not working properly is check your tire pressure. A low tire pressure can cause wheels to rotate more easily, thus compensating for a weak link in the suspension system.

This could also pose an injury risk because the vehicle will be less stable due to poor traction. Make sure both front and rear tires are the appropriate pressure and that there is enough tread left on them!

You may also need to replace or re-inflate your car’s run-flat safety belted tires. This way, you can still get some use out of the vehicle even if one of the normal tires goes flat. Some people choose to buy new tires before replacing the run-flat ones so that they don’t have to worry about finding replacements later.

Another part which can contribute to bad performance is wheel alignment. Because torsion bars work by twisting the axle shaft as it rotates, a poorly aligned wheel can prevent this twist from occurring, resulting in weaker damping. You can try bringing these things yourself but only if you know what tools you have and how to use them. More expensive dealerships and mechanics usually can handle this for you.

Practice riding to ensure you are comfortable with the bike before making any adjustments

The t-bar or track bar is one of the most important parts of your motorcycle, as it determines how far back your front wheel can drop.

With a low t-bar setting, your rear end drops lower and feels more stable, but this also means that when you brake, the wheels lock up earlier, creating some scary situations.

On the other hand, if the t-bar is set too high, then the front forks will not compress enough which could cause excessive bounce and poor handling.

This article will talk about two ways to adjust your t-bars for different types of riders and conditions.
