MWX Performance is clearly going all-in to elevate the RC28 into a serious contender in the 1:28 scale racing scene. Here's a breakdown of the upgrades we are engineering to push this platform beyond its stock limits:
MWX RC28 Upgrade Breakdown
1. Linear Front Spring Set
- Multiple rates available for precise front-end tuning
- Improves steering response and corner entry stability
- Ideal for adapting to different track surfaces and grip levels
2. Upgraded Center Shock
- MWX’s R1 Dual Spring Shock Kit offers enhanced damping control
- Threaded body for preload adjustment
- Dual-spring setup improves mid-corner support and exit traction
3. New Upper Deck Design
- Engineered to accommodate high-performance stock ESCs
- Optimizes weight distribution and chassis rigidity
- Allows cleaner wiring and better airflow for cooling
4. Burned Titanium Screws
- Lightweight and corrosion-resistant
- Available in multiple sets for chassis, motor, and front-end assemblies
- Adds bling and performance — less rotating mass, more durability
Why These Matter
MWX isn’t just throwing parts at the RC28 — they’re strategically refining the platform to maximize performance in key areas:
- Suspension tuning for sharper handling
- Shock upgrades for better grip and consistency
- Chassis optimization for electronics and weight balance
- Hardware refinement for durability and reduced weight
Ah, now we’re talking about one of MWX Performance’s most game-changing innovations for the RC28 platform — the MWX Slipper Differential (MX-SLPD-500). This isn’t just an upgrade; it’s a redefinition of how 1:28 scale cars handle power and cornering.
⚙️ MWX Slipper Differential: Key Features
- Hybrid Performance: Combines the best traits of gear and ball diffs. You get the straight-line stability of a gear diff and the cornering finesse of a ball diff — without the drawbacks of either.
- Controlled Slip: Designed to slip and rotate the car simultaneously. In modified classes, this helps manage power delivery on exit. In stock classes, minimal slip smooths out corner entry for faster lap times.
- Maintenance-Free Design:
- Built dry — no lubrication needed on plates or pins.
- Virtually zero rebuilds required; just a drop of oil on the outer bearing occasionally.
- Break-in improves performance over time, unlike ball diffs that need tightening.
Build & Materials
- All 7075 Aluminum Components: Black anodized for durability and style.
- 53T Yellow Spur Gear: Easy to identify and replace.
- Floating Thrust Bearing: Now with tighter tolerances for better feel.
- Mirror-Finished Roller Plates: Reduced friction and wear.
- Universal Drive Hub: Added clearance for adjustable collar setups.
Tuning Philosophy
- Never run it locked down — tuning is based on driver feel.
- Ideal for momentum drivers, point-and-shoot styles, and everything in between.
- Offers a unique steering characteristic that’s nearly a perfect split between gear and ball diffs.
This slipper diff is already making waves — multiple national and regional wins, even a national title, have been claimed with it in 2024.
