No tools needed to dial in your preferred ride height and firmness.\u003c\/p\u003e\n\u003ch3\u003eWhat finish options are available?\u003c\/h3\u003e\n\u003cp\u003eProgressive 444 shocks come in black or chrome finish, both paired with standard or heavy duty spring rates.\u003c\/p\u003e\n\u003ch3\u003eIs there a warranty?\u003c\/h3\u003e\n\u003cp\u003eYes — Limited Lifetime Warranty on manufacturing defects.
