Rear wing choice matters when every ounce of performance counts.

The JConcepts Finnisher Polycarbonate Pre-Trimmed Rear Wing brings a lightweight, competition-focused aero option to 1/8 off-road buggy racing. Formed from heavy-duty 1.5mm polycarbonate and weighing just 28.6 grams, the Finnisher keeps weight low while providing the strength and shape racers demand.

Its aggressive one-piece design features a lowered center section for a low-profile stance, taller side dams for stability, seven rear support ribs, and a taller tunable gurney to help dial in rear grip and high-speed balance.

Best of all, the wing arrives pre-trimmed with clean factory-cut edges, saving prep time and getting your buggy closer to race-ready right out of the package.

Lightweight. Tunable. Pre-trimmed. The Finnisher is built for racers looking to fine-tune the final piece of their 1/8 buggy setup.

Some crawler builds deserve more than an ordinary wheel.

The JConcepts Jammer 2.2” Crawler Wheels are a premium upgrade built for rigs where every detail matters. Clear anodized aluminum construction gives the Jammer a clean, high-end finish, while the stepped wheel face, pass-through triangular openings, machined bead lock rings, and recessed hardware create a look that stands out from every angle.

Need to fine-tune width and stance? Optional 5.5mm, 6.5mm, 7.5mm, and 8.5mm adaptors bolt directly on for added adjustment.

Premium materials. Detailed machining. Real tuning options. The Jammer wheel set is built for the crawler enthusiast who wants their rig finished properly from the ground up.

Includes 4 wheels, hardware, steel inner locking hoops, 4.5mm adaptors, and longer starter screws to assist with bead installation.
