Powerflex Front Thrust Arm Bushings are the ideal replacement for the worn-out bushings on your G29 Z4 and Supra. Not only will these provide a noticeable improvement in performance, but they're guaranteed to last a lifetime!

The stock bushings contribute the most to steering vibrations and poor handling feel. As the rubber wears out the bushing can no longer dampen the movements of the suspension. Replacing an original rubber part with OEM is inviting the same problems to return. HD bushings are a great compromise but are too close to stock OEM rubber. For the true enthusiast who feels the G29 is not sporty enough the Powerflex are the only option!

Powerflex has extensive experience in automotive suspension and chassis systems and has combined these skills with advanced polyurethane manufacturing techniques. Durometer is standardized per fitment and location, so you can rest assured knowing the design engineers have selected the optimal urethane hardness for this specific part.

This bushing also features an offset eccentric shape so caster can be adjusted. By loosening the inside nut and rotating the collar screw you can change caster settings on the G29/Supra upper thrust arm.

Note: Powerflex copper-based grease is supplied with every bushing set, and they will rarely need re-lubing due to the unique design features built into the material to hold the lubricant.

Lifetime warranty.
