NRG FRP-301 Fiberglass Bucket Seat – Large | FRP-301

NRG’s FRP-301 fibreglass bucket seat in Large. Single-layer FRP (Fiber Reinforced Plastic / fibreglass) shell construction — NRG’s entry-level bucket seat line. Lightweight shell with race-style bolstering, harness slots for 5-point harness use, and universal mounting. Suited for street-driven enthusiast and project cars seeking a lighter, more supportive seat than factory. Seat brackets sold separately. Single seat — driver or passenger.

FRP Shell Construction

The FRP-301 uses a single-layer fibreglass (FRP) shell — the same basic construction as most entry-level bucket seats in this price range. Fibreglass provides a meaningful weight reduction over factory foam-and-frame seats and a stiffer, more supportive structure for performance driving. It is not carbon fibre and is not double-layer FRP — this is an honest entry-level shell seat at an entry-level price. The shell is suitable for street use and occasional track/autocross use. For sustained motorsport or high-impact applications, a higher-rated seat (FIA-certified) is appropriate.

5-Point Harness Compatibility

The FRP-301 has harness slots positioned for a 5-point racing harness — lap belts, sub-strap, and shoulder belt pass-throughs are built into the shell. Using a harness requires proper chassis mounting points: a harness bar, roll cage, or OEM-style mounting with the correct geometry. Harness installation on a street car without a roll cage or harness bar is strongly discouraged — the shoulder straps must be mounted correctly to function safely in a collision.

Sizing — Large

The FRP-301 is available in multiple sizes — this listing is the Large size. The Large shell is suited to larger drivers or those who prefer a less restrictive bolster fit. If you are between sizes, NRG’s sizing guide (available on their website) provides shoulder width and hip width dimensions for each shell size. Verify the seat dimensions match your body size and vehicle interior clearance before ordering.

Universal Fitment — Brackets Required

The FRP-301 is a universal shell seat — it uses NRG’s standard side-mount interface. To install in a vehicle, you need:

• Vehicle-specific NRG or compatible side-mount seat brackets — sold separately
• Optional: seat sliders if you need fore-aft adjustment

Verify bracket availability for your specific vehicle before ordering the seat. NRG and aftermarket suppliers offer brackets for most common enthusiast vehicles.
