This listing is for a Full Set of 8x High Tensile Steel Threaded Hinge Pins for the Traxxas XRT Set includes: 2x Short Hinge Pins 6x Long Hinge Pins 8x Retaining Nuts These are an equivalent part to RPM70510 or CEN GS025 and they are made from high tensile steel and use bigger retaining nuts than RPM etc. If you've ever remotely bashed your Traxxas XRT, you've probably 'popped a pin out' at least once (if not much more often). These completely eliminate that from happening. Unlike other threaded hinge pins available, we have these made from premium High Tensile Steel making them much less likely to bend or snap, unlike some others which are made from regular stainless steel (A2 or A4) which will bend and snap easily. This kit includes enough hinge pins to do the rear lower and upper outer arms, both front inner upper arms and the front lower outer arms. (See photos for fitting instructions). It is not recommended to use these on the front upper outer arms, as the pin head will interfere with the steering knuckle at full steering lock and reduce your turning radius. Fitting Notes: You will need to use a 4mm drill bit to open up the 3mm retaining hole in the outer arms to allow these new pins to pass through to fit the nut on the other end. You do not need to drill the inner upper arms, just remove the stock pin retaining screws from both sides before fitting these threaded pins. **These pins are not indestructible! If you bash or crash them hard enough, they can still bend** (you can easily bend them back again as part of your after bash maintenance) Postage is FREE via Royal Mail 1st Class (UK Only) and $17USD for the rest of the world (via Priority Airmail) and items are dispatched within 24 hours of receiving payment.
