The lightweight carbon fiber chassis works together with strategically positioned brass components to achieve the ideal combination of chassis flex, weight distribution, and center of gravity. This combination provides excellent traction, predictable handling, and consistent performance across a wide range of track conditions.

Another key feature of the XB-SF is its front ride height adjustment system. Precision stainless steel shims are installed between the carbon chassis and the Simple Front assembly, allowing front ride height to be adjusted quickly and accurately without affecting camber, caster, or any other suspension settings. This enables fast, repeatable setup changes while preserving the car’s suspension geometry.

The redesigned damper plate features a new side spring geometry that has been carefully optimized to improve chassis rotation while maintaining stability and rear-end traction. By relocating the side spring mounting positions, the XB-SF delivers a more responsive feel through corner entry and mid-corner, resulting in improved rotation and overall balance.

To preserve the natural flex characteristics of the chassis, the XB-SF features a floating servo mount that prevents the servo from influencing chassis twist. This allows the chassis to flex exactly as intended, resulting in more consistent handling and improved cornering performance.

The redesigned center pivot assembly features a simplified design with improved precision, ensuring smoother suspension movement, easier maintenance, and greater consistency on the track.

The XB-SF also features the Xbility 3-Point Ball Differential, a design pioneered by Xbility that has become recognized for eliminating wheel play while maintaining exceptional drivetrain precision. Its unique three-point wheel mounting system ensures perfect wheel centering, smooth operation, efficient power delivery, and outstanding reliability.

The newly developed V2 motor mount lowers the motor position by 0.5 mm, reducing the center of gravity and improving chassis balance. Complementing this is the V2 brass left motor mount, which strategically adds weight where it is most effective to optimize left-to-right weight distribution and achieve the ideal chassis balance.

The XB-SF kit is supplied with one pair of 11 mm rear wheels, one pair of 8.5 mm front wheels, and one pair of 23 mm front side discs, providing the ideal wheel package for the Simple Front suspension straight out of the box.

Every component of the XB-SF has been designed with a clear purpose: to simplify assembly and maintenance while maximizing performance. The result is a chassis that is easy to understand, easy to tune, and capable of competing at the highest level.

Silver Horse RC Ride Height Gauges — SH0271

Every tenth of a millimeter matters when you're chasing the perfect setup. Our Ride Height Gauges take the guesswork out of the equation, giving you dead-accurate readings so your car sits exactly where you want it — every run, every track, every time.

This set pairs two gauges for complete coverage:

• Fine-range gauge — 1.0mm to 2.0mm in 0.1mm increments, for dialing in the lowest, most sensitive part of your ride height range.
• Double-sided gauge — covers 1.8mm to 4.0mm, with odd and even tenths split across the two faces for maximum accuracy across the higher end of your setup range.

Machined from durable composite with laser-etched markings that won't wear off in the pits, these gauges are built to survive raceday abuse and keep reading true, race after race.

What's included:

• Fine-range gauge (1.0–2.0mm, 0.1mm increments)
• Double-sided gauge (1.8–4.0mm, odd/even faces)

Dial it in. Race with confidence.

Silver Horse Blasting Bag

Race-Ready Thermal LiPo Charging and Storage Bag

Keep your batteries warm, contained, and ready to run.

Cold LiPos rob you of runtime and punch. The Blasting Bag keeps your packs at fighting temperature while they charge, so you're never waiting around for a sluggish battery to wake up — a small detail that makes a big difference in your pit setup.

FEATURES

WHY IT MATTERS

A cold pack is a slow pack. The Blasting Bag keeps your batteries at optimal temperature through the charge cycle, so they're ready to deliver full power the second you hit the track — not ten minutes after you pull them off the charger.

And it does it safely. Fire-safe construction means peace of mind whether you're charging on the bench, in the pits, or in the trailer.

Built by racers, for racers — because a cold pack shouldn't cost you the race.

Specifications:

Complete Double A Arm Front Suspension for your RX28 or GX28.  

SILVER HORSE RC — CYCLONE+
A twister in your hand.

Out here, dust settles on everything — your bearings, your diffs, your good sense. The Cyclone+ don't care. Double the battery of the original, this thing kicks up a wind that'd strip the paint off a barn door if you let it get too close.

One hand's all it takes. Point, squeeze, and watch the grit run for the hills. Bearings, motors, chassis, gear cases — nothing hides from the Cyclone+.

Pop the hood and you'll see why — a precision turbine fan behind that honeycomb grille, engineered to move serious air without choking on itself. That's not a gimmick guard. That's the difference between a toy and a tool.

What it's packing:

• 2X the battery of the original Cyclone — more wind, less waiting
• Precision turbine fan behind a honeycomb intake guard
• One-hand draw, built for quick work at the pit table
• Knurled grip that won't slip when the trigger's wide open
• USB-C rechargeable — no fuss, no wall-wart huntin'
• Compact enough to holster, mean enough to matter

In the box:

• Cyclone+ powerful blower
• Rubber focus tip
• USB charge cord
• Velvet carrying bag, to keep your Cyclone safe when it ain't kicking up dust

Heads up: the new Cyclone+ stands 10mm taller with a handle 2mm thicker than the original. Current tool racks are built to fit both the old and new Cyclone.

Fair warning: this ain't a toy fan for cooling off on a hot day. Get careless with it near loose parts, small hands, or your good composure, and you'll learn that the hard way.

Silver Horse RC — Cyclone+. When the wind needs to mean business.

Silver Horse RC — High Noon  - Portable Racing Pit Light

There's a moment before every good showdown. The light's low. Shadows stretch long across the dirt. And somebody's about to lose.

Not you.

High Noon rides with you. It folds down small enough to disappear into a 7" x 7.75" x 3.5" packing cube — tuck it next to your pit bag, your radio case, wherever there's a small space, because there's always room for this. But don't mistake small for weak. Unfold it, and it throws enough light to fill an entire room. Every corner. Every shadow, gone.

24 watts of stepless, dial-it-your-way brilliance, from a cool 3000K workday white to a blazing 6500K daylight blast. Five brightness levels. Five color temps. One touch panel that does exactly what you tell it and nothing you didn't.

Two arms, one mission. The main light throws down a 270° swing, and the auxiliary arm bends 215° either direction — so the light finds your work, not the other way around. Clamp it to a table up to 2.5 inches thick, or drop it in the included base. Set in seconds. Not moving again till you say so.

Pack it up, and it's gone — folded flat, out of the way, ready for the next town. It's even got a memory: a 30-minute auto shutoff, for when you forget it's on. Even a gunslinger's gotta walk away sometime.

High noon hits different in the pits.
