1st. Gen: This product was inspired using race car technology. By utilizing quick release kits, drivers were more easily able to enter and exit their bucket seat equipped vehicles. We understand this and offer the quick release kt as a solution. Made from the best quality aluminum available, and thouroughly tested for smooth engagement, a snug fit, and repeat use, it does not get any better than the NRG Quick release. 2nd Gen: All the features of the above, including anti-scratch construction, self-locking mechanism, and bodies available in different colors as well. 2.5 Gen: Another upgrade utilizing all the features of the Second Generation Systems with the added benefit of a flared ring. This allows much easier release for the steering wheel by providing added leverage and grip onto the pull ring. Perfect for race applications where the use of gloves are required. Rings are also interchangeable for a variety of different color combinations.
