Among the many car parts we take for granted, there is one that we only remember when something goes wrong. This is the door check strap. Unnoticeable in everyday life, it performs a simple but very important function: it holds the door in an open position, prevents it from suddenly swinging open or slamming shut with the slightest breeze, on slopes, or when passengers are getting in or out. It is thanks to this mechanism that we don’t think about how to hold the door when our hands are full, or how to protect the body from accidentally hitting a wall or another car.
Over the years, this mechanism wears out. The clear fixation disappears, the door begins to “fall through,” crunching or squeaking is heard. And then many drivers ask themselves: what to do? Replace the entire check strap? Go to a service station, order a new unit, wait several days for delivery, and pay a considerable amount?
In fact, the solution is simpler and smarter. If the base of the check strap is not broken, it is enough to replace only the worn internal elements — those same retainers, bushings, or rollers responsible for fixation. That’s exactly why we, the ANT Manufacturing team, have developed over a thousand repair kits for different car makes and models. These are precisely shaped and sized parts, manufactured by injection molding from PA6 polyamide with graphite additives — a material that withstands high loads, temperature fluctuations, and lasts longer than original components.
In each kit, you will find everything you need: ready-made retainers (for 2 or 4 doors), special lubricant, an illustrated manual with clear explanations on how to replace them yourself without a service station or special tools. And most importantly — it costs several times less than a complete replacement of the check strap.
If your doors no longer hold, slip, crunch, or get stuck — it’s not the end. It simply means it’s time to update the retainer that silently works every day for your comfort. ANT Manufacturing is a Ukrainian manufacturer trusted by thousands of drivers. Check if there is a repair kit for your model on our website or write to us in messenger — we will find everything in just a few minutes.
You don’t have to buy a new unit — just replace the parts that have worn out.
