LATEST VERSION of the tried and tested true ZERO "slop" steering quick release SET (2 pieces). Few parts in the motorsport industry are really revolutionary - but this one is definitely the market leader and it just got better!The boss accepts any steering wheel with a 6 x 70mm PCD bolt pattern such as Momo, OMP, Sparco, Motacorsa and many more. No welding is required as the boss bolts directly to a 6 x 70mm PCD steering wheel adaptor.The added features of this new version is larger internal parts, without any increase on the overall external dimensions, and this change permits the use of a 22 pin Deutsch German electrical connector (SEE PART# QR-03-22P), all at a VERY competitive price. We have some customers who have stated they only need 6 or 11 pin connections, we still recommend this (QR-03-22P) version as it is much cheaper than the older version with electrical connector. Since when you order the version with electrical connectors installed (QR-03-22P) the pins and sockets are not fitted (you fit them to suit your electrical requirement), you can install only the number of pins required - and it is still cheaper than any other option.This part number (QR-03) is without the electrical connector.This coupling is unique in many ways. Splined products do not offer zero "slop" movement, and suffer from wear issues and they age, becoming sloppy. Most brands also don't index the wheel so it is straight when you click it on, and as well, they do not give you a positive lock indication so you know the wheel is in fact securely locked on the car. With this product you can forget all of these issues, it just works, and very well at that!The Krontec steering coupling system is completely different. This part number has a Bolt-On Boss where you can mount it to the bolt pattern on your steering column. You can see other options in our site - such as weld on bosses. We can even supply the couplings with Professional German electrical connectors fitted, allowing your data to be neatly passed through the coupling point and avoid ugly and cumbersome cables.The Male portion of the boss is both tear-shaped and tapered depth-wise. This coupling centers the steering wheel perfectly and glides on with absolute ease, whilst providing complete confidence your steering wheel is 100% locked and cannot come off unintentionally.The dimension for the quick release steering coupler QR-03 when both halves are joined is 46.50mm overall depth, for more detailed dimensions see the attached PDF highlighted in Orange below.One of the most critical components to your vehicle is the steering components, can you afford to be without our solution - we believe not!
