If you have lifted your vehicle, you have noticed that your vehicle wanders on the road more easily than before. The reason for this is the loss of caster angle in the front axle. As your vehicle gets taller and the radius arms and front axle angle downward, you lose your caster angle. Furthermore, the bushings between the radius arms and the frame crush in a downward fashion from the excessive downward angle of the radius arms.

To correct these problems, fit your Land Rover with a set of our offset radius arms. Fitting offfset the radius arms will maintain the factory caster and bushing angles on a lifted vehicle.

Different vehicles have different amounts of lift and different size tires. We will comply with your request for different amounts of angle and length to suit your needs. Please consult with us regarding your specific needs.

As with our rock sliders, We ship the offset radius arms to you in a sturdy wooden crate to protect the radius arms in transit. Do not discard this crate, but rather use it to encase your radius arms that you will return to us.

The construction is very beefy, much more substantial than the similar arms from other makers. We can state with certainty and comfort that the welded radius arms are perfectly safe. One of the reasons we use welding to manufacture the offset radius arms is that heated and bent radius arms will necessarily become shorter as they are bent. Our cut and welded radius arms can be made in any reasonable length the customer requests.

Before beginning work, ensure that your vehicle is parked on a flat surface with the parking brake securely engaged. Let your vehicle stand for a while to let the engine and exhaust components cool completely. Otherwise, you may burn yourself on the catalytic converters or other hot components.

If your vehicle is muddy, do yourself a favor and hose away as much mud and debris as you can. You will be hammering under your vehicle and if your undercarriage is dirty, you will constantly get particulate matter in your eyes as you work.

Before removing your radius arms, check to see if anything is tied or otherwise connected with your radius arms. In the above photo, you can see that the front breather tube is zip-tied to the radius arm. Many people with ARB lockers route the air line along the radius arm. If you have anything tied to your radius arms, remove it before removing the radius arm.

Chock the wheel next to the radius arm you intend to remove to prevent excessive movement of the axle while the radius arm is removed.

Unthread the nut securing the rear of the radius arm to the body. This nut is usually very tight, so use a long breaker bar or pipe to obtain the necessary leverage. Loosen the nut but do not remove the nut at this stage.

Unthread the large fasteners securing the front of the radius arms to the axle. The radius arms are extremely heavy. Be prepared when the front of the radius arm falls away from the axle. This is the reason to leave the nut on the rear of the radius arm, in case the front of the radius arm drops uncontrollably.

To drop the radius arms completely, you will have to undo at least one end of your tie rod. Once the tie rod is removed, you can remove the arm completely and refit the offset arm before doing the other side.

Your radius arm fasteners may be corroded from several years of use. You can reuse them if they are still serviceable. However, if your fasteners are questionable, purchase new ones. When refitting these fasteners, coat them with waterproof grease to prevent future corrosion.

Here is a view of the RoverTym offset arm compared to the stock arm. Note that the RoverTym arm has an identical angle for the bushings as the stock arm, but has 3" of drop from the axis of the radius arm's stud mount. The radius arm pictured here is also slightly longer than the stock arm per the customer's order.

Check your bushings for wear. The bushings pictured above were dirty, but still in good shape and very serviceable.

Before refitting the bushings, clean them thoroughly and grease their mating surfaces before attaching them to the frame. Also grease all the mating surfaces of the front bushings and the mounting stud on the rear of the radius arm.

Fit the offset arm to the vehicle in reverse of the instructions above. The holes for the fasteners on the offset radius arm will not readily align with those of the stock arms. To achieve the correct fit, use a bottle jack under the radius arm and lift the arm in small increments to align the holes.

Insert the greased bolts into the aligned holes between the radius arms and the axle. Before tightening the fasteners, thoroughly degrease the threads with brake cleaner and apply red Loctite to prevent the fasteners from vibrating loose.

After fitting one of the offset radius arms, the second one will install more easily than the first because the attachment points will align more easily.

Here is a view of the completed job. Our offset radius arms are considerably thicker than the stock arms, so check the adjustment of your steering stops to ensure that your tires don't rub against the arms. Upon completion, double check to ensure that all fasteners are tight and pack your stock radius arms into the wooden crate and ship them back to us.

Enjoy your new radius arms!
