The ride is better on bumps, and the back end doesn't feel like it's sliding out when driving around bumpy corners on poorly-maintained city streets. The ride is not harsh at all - it feels comparable to the factory ride. But there is definitely more control and better handling now, while sharp bumps in the road just dissappear. The giant car isn't a sports car by any stretch, but combined with the 18" wheels and Michelins that I'm using now, it really is night and day. I hadn't planned to replace the front struts, but I'm totally doing so now.Originally I had just purchased cheap Monroe "sens-a-trac" shocks, but one of those blew out the first day, and they really didn't work well. As usual, you get what you pay for.One more note - get the SM5267 kit. You don't need everything in that kit, but having new nuts and the upper bushing is convenient. ### ⭐⭐⭐⭐⭐ KYB top Tier Suspension standard for years *by J***Y on Reviewed in the United States on November 1, 2021* Easy to install, consistent quality standard, I did not have issues years ago, have not needed shocks and struts for years and got reacquainted in recent moths to be reminded Top Tier companies are still the way to go. ### ⭐⭐⭐⭐⭐ These work with no complaints or regrets *by R***D on Reviewed in the United States on January 9, 2020* I put these on my wifes Lincoln. They are a great improvement over the NEW shocks I had put on less than a year ago. I was afraid they would be to harsh for her liking. However they are fine. They ride firm and rebound nicely and actually reset the ride height . The other shocks would bottom out hard . I like them for this car. I should have used them to start with. I got them for all 4 corners on my Charger and my brothers last year. KYB has been a brand you can trust for years. --- ## 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.us/products/11521504-555601-gas-a-just-gas-shock](https://www.desertcart.us/products/11521504-555601-gas-a-just-gas-shock) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-26*
