Pick your firmness: 51A for the loosest, most responsive turn, 61A for the classic loose feel, or 71A for a tighter, crisper feel. Each set includes four washers, so you can fine-tune the fit or run without them. Durometer 51A / 61A / 71A Type O-Ring Bushings Material Custom molded silicone ← looser turnfirmer / more stable → 51A Loosest 61A Balanced 71A Firmest Pick your durometer at checkout. Includes: Pro Duro O-Ring Bushings in Clear Glow, in your selected durometer (51A / 61A / 71A) (4) washers, usable with or without Details One mold, three feelsEvery Pro Duro O-ring is molded to the same shape with the hole in the same spot, which is the part stock O-rings get wrong. Because the shape stays fixed, the only thing that changes between sets is firmness, so you can swap durometers and know exactly what you're adjusting. Clear Glow glows in the darkClear Glow is UV reactive. Charge it under a light and it glows once the room goes dark. Same custom molded silicone and same feel as the rest of the line, it just does a little more once the lights are off. Reading the durometerLower numbers turn looser. 51A is the softest here, with the most truck movement and the quickest response under your fingers. 61A sits in the middle and feels close to Teak's original O-rings, just more consistent. 71A is the firm one, tighter through the turn for crisper pop and lock-in on technical tricks. All three ride on the A scale used for bushings and tape. Washers, and when to skip themThe four included washers secure the O-rings against the truck and give you a more controlled feel. Run the bushings without washers and you'll get an even looser, sloppier turn that some riders like. One catch worth respecting: without washers, do not crank the locknut down hard, since overtightening crushes the bushing. What they hold up toThese take real wear and tear before they need replacing, which is more than you can say for the O-rings that ship on most trucks. When the turn starts feeling vague, that's the cue to swap a fresh set in. Compatibility & FitFits all major fingerboard truck brands, including Teak Spacer, Prodigy Pro, Tech Deck, and UAG, plus wider-kingpin trucks like Dynamic and Y-Truck. On Y-Trucks the washer seats a little more snugly. Pivot cups in this style fit every major truck except Blackriver. Frequently Asked Questions What actually changes how my truck turns?The bushings, the O-rings, and the pivot cup, not the nut. Tightening the locknut clamps everything down and limits movement, but it's the bushing durometer that sets the real feel. Swap to a softer O-ring for a looser turn or a firmer one for stability, and use the nut only for fine adjustment. Will these replace the O-rings on my trucks?Yes. Pro Duro O-Rings are made to drop in where your stock O-rings sit, so you pull the old ones and run these instead. They hold their shape and last longer than the rings most trucks ship with. Which durometer should I pick?Start with the turn you want. 51A is loosest. 61A is the classic middle. 71A is firmest. Softer leans and reacts faster, firmer stays crisp and stable. If you are unsure, 61A is the safe middle. Softer or firmer, what's the difference in plain terms?Softer (lower number, like 51A) lets the truck lean and turn more easily and reacts faster. Firmer (higher number, like 71A) resists the lean, so the board feels more planted and controlled. It comes down to whether you want a turny setup or a stable one. Do these fit my trucks?They fit all the major brands, Teak Spacer, Prodigy Pro, Tech Deck, UAG, and wider-kingpin trucks like Dynamic and Y-Truck. The washer just sits a touch tighter on Y-Trucks. If you're buying these as a gift, check the truck brand against that list and you're set. Can I run them without the washers?You can. Skipping the washers gives an extra-loose turn that some riders prefer. Just go easy on the locknut if you do, because without the washer there's nothing stopping you from overtightening and damaging the O-ring. Pairs well with Pair them with a set of Pro Duro pivot cups to tune the rest of the truck. Want a bit more rebound? The Pro Duro Bubble Bushings are the upgrade pick.
