Rc use. Im gonna run it. Cheaper than rc brands by volume. **Q: If I have air forks, do I need suspension fluid?** A: Yes, you absolutely need suspension fluid. An "air fork" has a sealed air chamber which functions as a "spring". When you the fork down, the air chamber compresses further and pushes back. It's pretty simple. This air chamber has rubber seals which use oil to lubricate the seals and prevent air from leaking. Also, there is typically a "damper" side to the folk (side of the fork which has adjustments for rebound, compression, etc.) which also requires oil. The charge damper should generally be left alone. It requires patience and finesse to properly change and bleed the oil. It would probably be worth taking your bike into a shop to have this done. Scratches to your fork could ruin it. It'd be cheaper to pay for service than pay for a new fork. **Q: Need Help Guys, when I add the oil should how should my rebound and dampening be set??** A: I have RockShox Recon 2006. It did not matter how it was set when adding oil. There was no pressure. The dampener was a pain to get back together because of the oil needing to work it’s way around seals and such. But after quite a bit of twisting it got back into place. Adding oil to the lower chambers was simply adding oil to two tubes. No settings really mattered then either. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice *by on Reviewed in the United States July 7, 2026* Good shock oil ### ⭐⭐⭐⭐⭐ For suspension adjustments *by on Reviewed in the United States June 24, 2026* Research suspension manufacturers recommend fluid ### ⭐⭐⭐⭐⭐ Made my fork work like new *by on Reviewed in the United States March 5, 2024* I used this oil on an old rock shop fork rebuild, made it work like new, very pleased ## Frequently Bought Together - RockShox Suspension Oil 15wt 120ml Bottle Lower Legs - SRAM Butter Grease, 1 oz - RockShox Suspension Oil, 5wt, 120ml Bottle, Fork Damper --- ## 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.sn/products/1429772-suspension-oil-15wt-120ml-bottle-lower-legs-rockshox-15wt-suspension](https://www.desertcart.sn/products/1429772-suspension-oil-15wt-120ml-bottle-lower-legs-rockshox-15wt-suspension) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-16*
