I mean the list literally goes on the damge that having any play let alone that much play on any part for that matter will cause over time cause is absolutely insane!! An the fact is there's absolutely zero reason and I mean zero reasoning for them to even need to have any play!! The manufacture should be using the right size bit and drilling out the hex hole so the extension nut is just snugged enough when sliding in the hex!! It's pure lazyness on the manufacturer's part.An yes all of this damage did happen to me and all damages were paid for outta my pocket not the sellers or manufacturers so be warned strictly crawlers and light light bashing or speed runs ONLY!!! NO JUMPING OR ANYTHING LIKE THAT!! ### ⭐⭐⭐⭐⭐ Made truck more stable but lost little steering. *by J***A on Reviewed in the United States on March 11, 2020* These wheel extensions helped my Gen 7 from tipping while turning on hills, made truck a little more stable. A negative is my turning radius got bigger but my truck is still stock, gonna upgrade steering next. I think my truck looks little better with the wheels sticking out . Work great would def recommend ### ⭐⭐ Disappointed.. *by J***R on Reviewed in the United States on November 15, 2020* I ordered a set of the 20mm. Unfortunately, they are NOT 20mm. I didn't realize, until I got my good set of actual 20mm hex hubs and was able to compare size. So either the product is not as advertised, or I just received the wrong ones on accident. My new ones are from HR and are marked 20mm. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/85468994-4pcs-12mm-wheel-hex-hub-20mm-extension-adaptor-longer-combiner](https://www.desertcart.tn/products/85468994-4pcs-12mm-wheel-hex-hub-20mm-extension-adaptor-longer-combiner) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-11*
