Top Redcat Racing Parts for Trail Driving: A Buyer's Guide

Quick answer

For trail driving, prioritize drivetrain durability and body protection over cosmetic changes. Start with a center drive shaft set if your rig sees rocks and roots, add a body washer and mount kit to keep the shell secure, and keep spare hardware on hand. Match every part to your specific Redcat model before buying.

Trail driving puts different demands on an RC vehicle than track running or bashing. You deal with low-speed torque loads, constant suspension articulation, and repeated impacts from rocks, roots, and uneven ground. That means the parts that fail most often are not the flashy ones — they are the drivetrain and body-mount components that take a beating every run.

This guide covers how to choose Redcat trail parts with a focus on real durability and fit. You will see which components are worth buying first, which ones are situational, and how to avoid the most common selection mistake: ordering a part that looks right but does not match your chassis.

What actually matters for trail driving

Trail driving is a sustained low-speed, high-torque activity. Your motor and driveline are constantly loading and unloading as tires grab and slip on dirt, gravel, and rock. That makes the center drivetrain and the body mounting system the two areas most likely to wear or fail. Cosmetic parts rarely affect how the vehicle performs on a trail, so they should come last in your budget.

The second factor is ground clearance and suspension travel. If you are adding taller tires or longer shocks, you need to check that your drive shafts and body posts still fit without binding. A part that fits a stock rig may not fit a lifted one, so always confirm compatibility before ordering.

• Prioritize drivetrain and body-mount parts before appearance upgrades.
• Check whether your rig is stock or modified before selecting any part.
• Keep a small stock of common hardware so a trail-side repair does not end your run.

Drivetrain parts: where trail durability starts

The center drive shaft set is the backbone of your driveline. On a trail rig, a worn or flexing shaft can cause vibration, power loss, and eventually breakage. A replacement set with a 90mm extension gives you room to work with lifted suspensions and longer wheelbases, which is common on trail builds. If you run bigger tires or a heavier body, this is one of the first parts to upgrade.

Transmission shafts are the other half of the equation. These are small, inexpensive parts that are easy to overlook until they strip or bend. Keeping a spare on hand is cheap insurance, especially if you drive in rocky terrain where sudden wheel stops put shock loads through the driveline.

• Replace drive shafts as a set rather than one side at a time.
• Inspect shafts for twisting or wear after every few trail runs.
• Carry a spare transmission shaft if you run in rocky areas.

Body and mounting parts: keeping the shell on

A loose or cracked body mount is one of the most annoying trail problems because it turns every bump into a rattle and can lead to a cracked shell. Body post mounts and plastic body washers are simple, low-cost parts that make a real difference. If your body shifts or vibrates, replace the mounts and washers before you spend money on anything else.

If your shell is already cracked or you want a fresh look, a replacement body with accessories lets you start clean. This is a bigger purchase, so treat it as a want rather than a need unless your current body is falling apart. A replacement body does not improve trail performance, but it does protect your electronics and makes the rig easier to see on the trail.

• Replace body washers when they harden or crack — they are cheap and prevent shell damage.
• Check body post mounts after any hard rollover.
• A new body is cosmetic unless your old one no longer protects the chassis.

Hardware and small parts: the cheap insurance

Screws, washers, and small fasteners are the least exciting purchase you will make, but they are the ones that keep you running. Countersunk hex machine thread screws in common sizes are used throughout most Redcat vehicles, and losing one on the trail can sideline you. Buying a pack of 12 means you have spares for multiple repairs.

The trade-off is storage and organization. Small hardware is easy to lose in a toolbox, so keep it in a labeled container. If you are unsure which screw size your model uses, check your manual or measure an existing screw before ordering — guessing leads to stripped threads and frustration.

• Buy hardware in packs so you always have spares.
• Label your hardware storage by size to avoid mix-ups.
• Measure an existing screw if you are unsure of the size.

Decision rules for buying Redcat trail parts

• If your rig is stock and running fine: Buy spare hardware and body washers first. They are the lowest-cost way to prevent a run-ending failure. Spend under $10 and cover the most common trail breakdowns.
• If you have lifted the suspension or added taller tires: Upgrade the center drive shaft set before anything else. A 90mm extension gives you the length to avoid binding. Drivetrain geometry changes when you lift — address it early.
• If your body rattles or shifts on bumps: Replace body post mounts and plastic washers together. One without the other rarely fixes the problem. Mounts and washers are a pair, not separate purchases.
• If you are unsure whether a part fits your model: Check your manual or measure the original part before ordering. Redcat makes many models and parts are not universal. When in doubt, measure twice and order once.

Product facts at a glance

• RER14673: Front & Rear Center Drive Shaft Set w/ 90mm extension (1set) A complete front and rear set with extra length suits lifted or long-wheelbase trail builds where stock shafts bind or wear quickly.
• RER41336: Body Washers (Plastic) (8pc) Eight washers let you refresh the body mounting on one rig and keep spares; worn washers let the shell shift and crack.
• RER18812: 4x16mm Countersunk Hex Machine Thread Screws (12pcs) A 12-piece pack of a common trail-vehicle screw size means fewer interrupted runs and less time hunting for a single missing fastener.
• 510143: Body Post Mount (F/R)(1pr) A front and rear pair replaces cracked or stripped mounts that cause body rattle and poor shell alignment.

Who this guide is for

Best for

• Trail drivers who run on dirt, gravel, and rock and want fewer breakdowns
• Owners of lifted or modified Redcat rigs who need drivetrain and body-mount parts that fit
• New Redcat owners building a small spares kit for trail runs

Not for

• Track racers focused on lap times rather than trail durability
• Collectors who do not drive their vehicles and only want display parts
• Anyone who has not confirmed their specific model and part compatibility

Trail driving rewards preparation more than peak performance. Start with the drivetrain and body mounting, keep a few spares in your bag, and confirm fit before every order. That approach keeps your Redcat running instead of sitting on the bench.
