Exclusive TC Kline Racing designed rear suspension height adjuster - Lower your car for the track. Raise it back up for street use. These adjustors are made from high tensile aluminum and have a special hard anodizing to ensure strength and durability.

Designed to be used with TC Kline Racing springs which have a 60mm inner diameter. The height adjuster can sit freely on the top or the bottom depending on your preference. 

When installing these adjusters and springs we remove the rubber spring pads on top and bottom in order to have a greater range of height adjustment and reduce the deflection rate caused by the rubber pads.
