RC Piggyback Shock Absorber Hole to hole 90mm 90046

The RC Piggyback Shock Absorber with 90mm hole-to-hole spacing (model 90046) is a precision-engineered suspension component designed for high-performance remote control vehicles and off-road buggies. Professional RC racing enthusiasts and competitive drivers rely on this component to achieve superior damping performance, precise handling, and consistent suspension response across varied terrain conditions. This shock absorber solves critical suspension tuning challenges by providing adjustable piggyback reservoir technology that enables independent compression and rebound damping control for optimal vehicle dynamics.

Product Overview

The RC Piggyback Shock Absorber 90046 features a dual-chamber design with an external piggyback reservoir that separates the main shock body from the damping oil reservoir. This architecture allows for increased oil volume capacity, improved heat dissipation during extended racing sessions, and enhanced damping consistency. The piggyback configuration enables racers to fine-tune compression and rebound independently, critical for adapting to different track surfaces, weather conditions, and driving styles. The 90mm hole-to-hole measurement ensures compatibility with standard RC buggy and truck chassis mounting points, making this a drop-in upgrade for competitive vehicles.

The shock absorber utilizes precision-machined aluminum alloy construction combined with hard-anodized finishing to withstand extreme racing conditions and corrosive environments. The internal piston design incorporates advanced shim stacking technology that provides progressive damping curves, preventing bottoming-out while maintaining responsive handling characteristics. The sealed design protects internal components from dust, mud, and water ingress, ensuring longevity in harsh off-road conditions. This model is engineered to deliver consistent performance across multiple heat cycles, making it ideal for endurance racing, competitive events, and high-speed track applications.

How to Use

Installation of the RC Piggyback Shock Absorber 90046 requires careful measurement and alignment to ensure proper mounting on your RC vehicle chassis. Begin by removing your existing shock absorbers and inspecting the mounting points for damage or wear. Position the new shock absorber with the piggyback reservoir facing outward away from the chassis to maximize heat dissipation and allow clearance for adjustment tools. Insert the mounting bolts through the 90mm hole-to-hole points and torque securely using appropriate hex wrenches, ensuring the shock body remains perpendicular to the chassis for consistent suspension geometry.

After installation, fill the shock absorber with the recommended damping fluid to the specified level marked on the reservoir. Allow the fluid to settle for 5-10 minutes, then perform several full compression and extension cycles to purge air bubbles from the system. Begin with factory-recommended damping settings, then conduct test drives on your typical racing surface to evaluate performance. Adjust compression damping first to control how quickly the suspension compresses under load, then fine-tune rebound damping to control extension speed. Keep detailed notes of your adjustments and their effects on vehicle handling, traction, and stability to develop your optimal tuning setup.

Frequently Asked Questions

What is the advantage of a piggyback shock absorber over a standard shock design?

Piggyback shock absorbers feature an external reservoir that increases damping fluid volume, improving heat dissipation during extended racing. This design prevents thermal fade that reduces damping performance in standard shocks during long races. The separate chamber also allows independent tuning of compression and rebound damping, providing superior handling precision and adaptability to changing track conditions compared to single-chamber designs.

How do I adjust the compression and rebound damping on this shock absorber?

The 90046 features separate adjustment knobs or screws for compression and rebound damping located on the shock body and piggyback reservoir. Compression adjustment controls how quickly the suspension compresses under load, while rebound adjustment controls extension speed after compression. Turn adjustments clockwise to increase damping (stiffer) and counterclockwise to decrease damping (softer). Make small quarter-turn adjustments and test drive between changes to identify optimal settings for your vehicle and track conditions.

What type of damping fluid should I use in this shock absorber?

Use only premium-grade RC shock absorber fluid specifically formulated for piggyback shock systems. Common viscosity grades range from 10-weight to 60-weight, with lighter weights providing softer damping and heavier weights providing stiffer damping. Consult the manufacturer's specifications for your vehicle class and racing conditions. Never use automotive shock fluid or substitute liquids, as improper fluid can damage internal components and compromise damping performance.

Is the 90mm hole-to-hole measurement compatible with my RC vehicle?

The 90mm hole-to-hole specification refers to the distance between the upper and lower mounting points. This measurement is standard for most 1/8-scale RC buggies and trucks. Verify compatibility by measuring the distance between your vehicle's shock mounting points or consulting your vehicle's technical specifications. If your vehicle uses different mounting spacing, adapter kits may be available, but direct compatibility is recommended for optimal suspension geometry.
