Installation & Warranty
Installation:

• It is imperative that the suspension be compressed to static ride height before any suspension pivot bushings are tightened, as per the factory installation procedure. If this is not done, the bushings will tear prematurely as the twisting forces on them will be much higher than is intended. 034Motorsport’s Limited Warranty on Density Line products does not cover premature failure due to improper installation or use.
• We highly recommend professional installation for this product.

Warranty:

• 1 Year Limited Replacement Warranty (If you encounter any issues with o034’s products outside of the warranty period, we will work with you to provide a resolution.)
