If you’ve ever rolled your HPI 5B and had the spark plug push through the stock protector, you need the RPM Roof Guard. The stock spark plug protector isn’t strong enough to handle serious inverted landings, which can easily damage or break the insulator of the spark plug.
The RPM roof guard is a low profile nylon plate that incorporates a large semi-spherical shape above the spark plug, keeping the plug free from damage during those accidental upside-down excursions. By using a semi-spherical dome over the spark plug, the design is simple, yet extremely strong. With the exception of the spark plug clearance dome, we keep the rest of the roof guard as low as possible to prevent the guard from detracting from the overall aesthetical appearance of this great-looking buggy.

RPM Roof Guards for the HPI 5B are made in the USA and molded in black from our superior blend of engineering grade nylons for the utmost in strength and durability. When protecting your ride is your primary goal, RPM has you covered!

#81972      Front Bumper & Skid Plate for the HPI Baja 5B

A lack of front-end protection of any R/C vehicle eventually results in hours of down time, replacing expensive chassis components from front-end impacts. The stock set-up on the HPI Baja 5B has virtually no protection up front since the bumper is tucked so far into the front of the vehicle. RPM steps in with some serious protection in the form of an all-new bumper specifically designed for this beast!

Our front bumper is a two-piece design, utilizing a skid plate and separate bumper that can be removed for racing. Each piece has specific design elements incorporated to dramatically improve the strength and durability of the HPI Baja 5B.

The RPM skid plate is attached to the chassis with four 5mm screws, not two like the stock version, effectively cutting transferred impact energy in half, divided equally among those four screws. Our skid plate also has huge skid rails all along its lower section and is a major part of the impact-absorption system. It extends up, out and away from the chassis, creating a large curved section that acts as a buffer zone that rapidly dissipates impact energy by compressing during a hit, slowing and absorbing that energy without transferring it into the more fragile components of the vehicle. Once the impact force dissipates, the memory characteristics of our trademark blend of RPM nylons will return the bumper to its original position.

The bumper itself is over 6-1/2” wide and is designed to prevent smaller objects such as fence and mailbox poles from slipping in-between the skid plate and the tires. Its added width tops off a perfectly balanced design that is strong, extremely durable and built to last!
Tech Notes: This bumper replaces HPI stock #85420 (item #2 on the tree).

Rear Skid Plate (fits all versions of the HPI Baja 5B & 5T)

The stock rear end of the HPI Baja 5B & 5T is not designed for low-end protection since the stock set-up has nothing in the back that needs protecting. However, large rear-mounted aftermarket exhaust pipes expose a critical weakness in the lack of protection those two tubes provide.

The RPM rear skid plate eliminates that weak point by eliminating those two tubes entirely. We replace them with a large, curved plate with seven huge skid rails measuring 1/4” wide by 3/16” tall that provide unmatched skid and impact resistance to the rear end. A small, open section was left to allow easy access to the clip holding the stock under-guard in place while closing up most of the back end so nothing can come up from the bottom to hit that expensive, aftermarket exhaust pipe. We also dropped the skid rails parallel to the lowest point on the chassis, helping reduce some of the impacts taken by the chassis and place it where it can be handled much better – by the RPM skid plate!

We made our rear skid plate beefy to handle tail-first landings or rear impacts, yet because it is made from our killer blend of proprietary materials, it can still absorb severe impact energy instead of transferring it into the more fragile and expensive chassis components.
RPM rear skid plates for the HPI Baja 5B & 5T are sold as three-piece kits and come with all necessary mounting hardware and instructions.

Tech Notes: This skid plate replaces HPI stock #85438 (item #4 on the tree). 
RPM rear skid plates are tested and only guaranteed to fit stock HPI parts and RPM aftermarket accessories.
