MASTERPIECE Caster Corrected Heavy-duty Front Radius Arms Jimny JB74 (2018-ON)
MASTERPIECE Caster Corrected Heavy-duty Front Radius Arms Jimny JB74 (2018-ON)
MASTERPIECE Caster Corrected Heavy-duty Front Radius Arms Jimny JB74 (2018-ON)

Great products for off-road driving with a lifted Jimny. In contrast to the original SUZUKI radius arms made of cast iron, this product is made of 42.7mm diameter and 5mm-thick carbon steel seamless pipes for machine structure (STKM13A). Also, 22mm thick steel material is used on the axle side. They have enough strength for off-road driving.

The lifted Jimny loses steering stability due to the change in caster angle, and the shortened wheelbase makes it easier for the tires to touch the body. However, these products correct the caster angle by about 5 degrees (good for the 2" lifted Jimny) or about 8 degrees (good for the 3" lifted Jimny), providing the perfect caster angle for lifted Jimny.

Also, three lengths are available: 5mm longer, 10mm longer, and 15mm longer than the SUZUKI original ones. Usually, 5mm longer types are good for 2" lifted Jimny, and 10mm longer types are good for 3" lifted Jimny. Longer types provide optimum wheelbase length for lifted Jimny. They are also very effective if you install larger tires or wheel spacers on your lifted Jimny. However, the longer types also have some disadvantages such as axle position misalignment, when the suspension is compressed. So, the suspension may touch the bumps stops or brake hoses during off-road driving. Also, a propeller shaft spacer may be required if you install more than 10mm longer type on more than a 4-inch lifted Jimny. The length of the radius arm must be carefully determined if using longer radius arms, especially when you are driving off-road.

Genuine SUZUKI rubber bushes, which are softer than aftermarket caster correction bushes, have been installed on these arms. They have great flexibility, so off-road suspension action movement is better than using caster correction bushes.


Comes with two Front Radius Arms with bushes.

* These products are heavy-duty products, but for those who love off-road adventure, High-bridge First Extra Heavy-duty Radius Arms are also recommended.
* In our experience, when an excessive load is applied, the original SUZUKI radius arms often bend and then break. However, due to the pipe shape of these products, they may suddenly break without bending. Even though these products are more durable than the original SUZUKI radius arms, please avoid dangerous off-road driving and do not neglect daily inspections.
* For your reference, in heavy off-road driving, the rear trailing arms are prone to damage on uphill slopes, and the front radius arms are prone to damage when hitting obstacles from the front. Especially, we have had some reports of the rear trailing arm of the JB74 (2018-present) failure on uphill climbs on hard off-road driving.
* Longer types are made-to-order and the orders may take a few weeks or more to ship. Please note that this product cannot be canceled after placing the order.
* Some colors are made-to-order and the orders may take a few weeks or more to ship. Please note that this product cannot be canceled after placing the order.
* If you purchase MASTERPIECE Rear Trailing Arms at the same time, we will refund 7,000 JPY. Please note that discounts are only available when purchasing the same color at the same time.
