When upgrading to performance springs, ensure that you don't skimp out on vital components such as the bump stops. Dinan offers premium Bump Stops that are designed to augment the performance of your custom suspension setup.

Constructed from certified OE materials, these reliable bump stops sport the needed travel and rebound features that cannot be achieved with urethane replacements. The Dinan Bump Stops are tuned for specific spring sets, ensuring that they match with the needed spring rates for each application.

The progressive rate allows the setup to maximize suspension travel, greatly improving handling and stability over factory bump stops. With full compression travel, there is no room for "bottoming out", which is quite a common issue with lowered ride heights.

The Dinan Bump Stops also optimize your ride's spring rate, resulting in better cornering capabilities especially at high speeds, all without abandoning a comfortable driving experience. Squeeze every ounce of performance from your trusty steed, with the amazing Dinan Bump Stops.
