The Best Body Washer for Rc Car

RC body washers might seem like a small accessory, but they play a big role in keeping your model’s shell securely mounted while protecting the paintwork from vibration and clip damage.

Whether you are racing on a track or bashing in the backyard, a proper body washer set reduces stress on mounting posts and helps your body stay in place through rough landings.

In 2026, the market offers a wide range of options, from simple foam discs to hybrid kits with clips, making it important to pick the right combination for your scale and driving style.

At BestProducts, we evaluate each product through a rigorous research process that includes analyzing specifications, expert review consensus, and verified buyer feedback.

We score every option on our 0, 10 BP Score to help you find a reliable body washer that fits your RC car without guesswork.

Below are our top picks, followed by a detailed buying guide to help you decide which set deserves a spot in your toolbox.

Best Body Washer for RC Car Buying Guide

Material: Foam vs. Nylon

Foam washers are soft and compressible, making them ideal for absorbing vibration and preventing scratches on painted bodies. They conform to the mounting post and work well with most body clips.

Nylon washers are harder and more durable, often used in combination with foam to provide a rigid base that keeps the clip from pulling through.

Many kits, such as those from Hobbypark, include both materials so you can layer them according to your needs.

If you are building a dedicated carpet racing car, thinner foam washers (around 1.5, 2 mm) help maintain a low profile. For off-road trucks and buggies, thicker foam (3, 5 mm) provides extra cushioning against big impacts.

Size and Compatibility

Body washers are not one-size-fits-all. Most 1/10 scale RC cars use an inner diameter of 4, 5 mm to fit over standard mounting posts. Common outer diameters range from 12 mm to 16 mm.

Universal packs like those from FriHobby offer a standard size that fits Traxxas, Arrma, Axial, Losi, and many other brands. Always check the inner diameter against your car’s body post before buying in bulk.

For larger 1/8 scale models or mini 1/18 scale cars, look for washers explicitly labeled for that scale. Many sellers list compatibility in the description; if unsure, a universal 25-pack gives you enough spares to experiment.

Quantity and Value

Body washers are inexpensive, so buying a multi-pack saves time and shipping costs. A typical RC car uses four to six washers per shell (one per post), meaning a 25-pack will cover several builds.

Kits that combine clips and washers, such as the Hobbypark 225-piece set, offer exceptional value for frequent builders who want a single restock solution.

Budget-conscious buyers can find high-scoring options like the Hobbypark 100-pack foam washers (BP Score 9.6/10) that provide plenty of material for multiple cars without breaking the bank. For the best overall experience, a mid-range kit with both foam and nylon gives you flexibility for different rigs.

Ease of Use

Installation should be simple: slide the washer over the post, then insert the clip. Some cheap washers have tight inner holes that require force to put on, which can damage the foam.

Look for sets with a cleanly punched hole and consistent thickness. Verified buyer feedback often mentions whether washers fit easily or need modification. Our research shows that Hobbypark and GoHobby models generally receive high marks for ease of installation.

Frequently Asked Questions

What size body washer do I need for 1/10 scale RC cars?

Most 1/10 scale cars use washers with an inner diameter of 4, 5 mm and an outer diameter of 12, 16 mm.

Universal packs from brands like Hobbypark and GoHobby are designed to fit the standard mounting posts on Traxxas, Arrma, Axial, Losi, and similar models. Always measure your posts if you have a custom or older chassis.

Are foam washers better than nylon washers?

Foam washers are better at absorbing vibration and protecting the body from scratches, while nylon washers provide durability and prevent clips from pulling through.

Many enthusiasts use both: a foam washer against the body and a nylon washer on top for rigidity. Kits that include both materials offer the best of each world.

How many body washers do I need per RC car?

A typical 1/10 scale buggy or truck uses four mounting posts (sometimes six on larger trucks). You need one washer per post, so four to six washers per shell. If you stack foam and nylon, you can double that count.

A 25-pack is enough for three to five cars depending on your setup.

Can I use body washers without body clips?

Body washers are designed to work with clips or pins. The washer sits between the clip and the body shell to distribute pressure and prevent damage. You still need clips to secure the shell; the washer alone does not hold the body in place.

Do body washers fit all RC car brands?

Most universal sets are compatible with popular 1/10 and 1/12 scale brands like Traxxas, Arrma, Axial, Losi, Redcat, HPI, and HSP. However, some micro or custom models may use different post diameters. Always check the product description for compatibility notes before purchasing.
