MXLR SLOW-MO Damper Grease 20K (Blue) – The RC Racer's Guide to Consistent Shock Tuning
When it comes to dialing in your RC setup, damper grease is one of the most overlooked variables on the bench. The wrong viscosity can throw off your shock feel entirely — too thin and your dampers blow through the stroke, too thick and the car feels planted in all the wrong ways. MXLR SLOW-MO Damper Grease 20K in Blue is built to eliminate that guesswork.
What Is Damper Grease and Why Does It Matter?
Damper grease is applied to the shock shaft and O-rings to control friction and seal consistency inside your shocks. Unlike shock oil, which controls rebound and compression rates, damper grease governs how smoothly the shaft cycles and how well the seal holds over repeated runs. A consistent damper feel means your setup translates from practice to race day without surprises.
MXLR SLOW-MO 20K – Key Features
- 20,000 weight viscosity – a medium-heavy formulation suited to a wide range of track surfaces and shock builds
- 15g container – enough to service a full set of shocks multiple times; practical for the pit bag
- Blue tint – easy visual identification on the bench; no mix-ups when running multiple weights
- Heat and cycle stable – holds viscosity under race conditions without thinning or migrating
- Stays in place – applied once, it doesn't need to be reapplied every run
Surface Compatibility
MXLR SLOW-MO 20K performs consistently across carpet, astroturf, and outdoor clay. The formulation doesn't break down under the heat generated by repeated shock cycling, which makes it a reliable choice whether you're running a club night on carpet or a full outdoor race weekend.
How to Apply Damper Grease
- Disassemble your shocks and clean the shaft and O-ring area thoroughly.
- Apply a small amount of SLOW-MO 20K to the shock shaft just above the O-ring.
- Work the shaft through the seal a few times to distribute the grease evenly.
- Wipe away any excess before reassembly.
- Rebuild your shocks and check for smooth, consistent travel before reinstalling.
A little goes a long way — the 15g container will last through many service intervals if applied correctly.
Choosing the Right Viscosity
The 20K weight sits in the medium-heavy range. If you're running lighter springs or a more sensitive shock setup, you may prefer a lower weight. If you're on a heavier car or a high-grip surface where you want more damper resistance, 20K is a strong starting point. MXLR offers multiple weights in the SLOW-MO line so you can tune precisely to your build.
Final Thoughts
MXLR SLOW-MO Damper Grease 20K is a straightforward, well-formulated product that does exactly what it's supposed to. If you're serious about your shock setup and want a grease that stays consistent from the first lap to the last, this is a reliable addition to your pit kit.
