The Long anticipated release is here. These Urethane Bushings not only replace the worn problematic #2 Caster Arm bushing up front on an IS300 (Also called the tension arm), they are specifically engineering to work in the rocker function that the stock version does. This means no egging out, no deformation, no noise, just performance. Press fit and assemble the center cylinder and end caps with the included grease and let the good times roll. We searched for 3 years for a great manufacturer to make these and SuperPro delivered. We invested the time so you can get them with 1-click, enjoy.
Set includes 2-Bushing sets for to replace both front arms.
I have heard that these are stiffer than stock. Will they reduce ride comfort and will they work with my other stock components.
These bushings are technically stiffer but only in the sense that they hold alignment under braking better than stock. This radial mount bushing is intended to rock back and forth as parts of its normal motion when the suspension travels. But it also needs to hold the alignment when the car brakes. In the OEM bushing it has to do both and not very good at either. Our bushings have a radius molded into the center bushing and two cap pieces to retain the bushing up and down. This 3-P design allows the bushing to rock like a bearing would but also support the lateral forces from hard braking. Its an improvement all around with no downsides to other components or tire wear. In fact because these bushings resist deflection under braking this will prevent toe changes and reduce inner tire wear. You will still need to align the car correctly afterwards as any previous alignment with worn bushings will be invalid. Lowered cars: Generally if the vehicle is lowered, we suggest more toe in up front to counteract bumpsteer.
Is there an install guide and will I need a press?
Yes we recently wrote up the installation process on our BLOG . A press is necessary to provide the proper alignment during installation and to prevent damage or distortion to the outer cup of teh bearing.
