By popular demand, Whiteline has finally developed and released their Positive Traction Kit for the 350Z & G35. The Positive Traction Kit is a rear differential mounting solution for high horsepower 350Z & G35 models that suffer excessive axle tramp under heavy acceleration. Whiteline’s rigorously tested low compliance Synthetic Elastomer bushings replace the extremely soft OE front and rear differential mount bushing and will dramatically reduce initial torque loss & differential movement during aggressive acceleration & deceleration. Whiteline’s Synthetic Elastomer bushing is the perfect solution for enthusiasts who want to firm up rear traction but do not want to endure the excessive noise and vibration that accompanies solid bushings. The Whiteline Positive Traction Kit for the 350Z and G35 include the upper bushings that mount the differential to the body as well as the rear bushing that mounts the rear differential to the rear cross member.
