Compare the Incision KMC XD820 Grenade aluminum beadlock and KM233 Hex molded beadlock for 1.9 RC crawlers. Decide by tire changes, weight, hubs, and budget.
Quick answer
Choose the Incision KMC 1.9 XD820 Grenade if you want an aluminum beadlock with fast tire changes and scale detail. Choose the Incision 1.9 KMC KM233 Hex Molded Beadlock if you want a lighter plastic wheel that works with common Incision hubs and costs less.
Weight and material change how the truck behaves
The XD820 Grenade is an aluminum beadlock wheel, so it adds mass low in the wheel and tire assembly. That can help stability on side hills and ledges, but it also makes each corner heavier to accelerate and stop. The KM233 Hex is a plastic beadlock wheel with aluminum inner and outer rings. Its lighter build suits rigs where you want to keep rotating mass down or where the motor and servo are already working hard.
Neither wheel is automatically better. Pick aluminum when you want the durability and scale look of a metal wheel, and pick the molded plastic wheel when weight and price matter more than metal construction.
Tire changes: five screws vs a full ring
The XD820 Grenade uses an internal clamp ring beadlock system that Incision says allows rapid tire changes with only five screws. That matters if you swap tires between courses or often test different foams. The KM233 Hex uses aluminum inner and outer beadlock rings, which means more hardware to remove and reinstall when you change a tire.
If you change tires often, the XD820 Grenade saves time at the bench. If you mount a tire once and run it for months, the KM233 Hex ring design is not a real drawback.
Hub compatibility is the hidden decision
The XD820 Grenade includes a #4 Incision hub and Incision states it will fit most stock applications. The KM233 Hex includes reinforced plastic #4 and #7 Incision hubs and is compatible with all aluminum Incision hubs using the hardware included with the wheels. That makes the KM233 Hex easier to adapt if you already own or plan to buy different Incision aluminum hubs.
Check your current hex size and axle setup before buying either wheel. If your truck uses an unusual hub, the KM233 Hex gives you more included hub options.
Decision rules for choosing between XD820 Grenade and KM233 Hex
- If you change tires often: Pick the XD820 Grenade. Its internal clamp ring needs only five screws per wheel, so you spend less time at the bench and more time tuning foams and tread. Count your tire swaps per season; frequent swaps favor the Grenade.
- If you want the lightest 1.9 option: Pick the KM233 Hex. Its molded plastic body and aluminum rings keep rotating mass lower than the aluminum Grenade, which can help small motors and light builds. Weigh your current wheel and tire to see whether the difference matters on your rig.
- If you need hub flexibility: Pick the KM233 Hex. It includes reinforced #4 and #7 Incision hubs and accepts all aluminum Incision hubs with the included hardware. The Grenade includes a #4 hub and fits most stock applications. Confirm your axle hex and hub type before ordering either wheel.
- If scale detail is the priority: Pick the XD820 Grenade. It is an officially licensed KMC aluminum wheel with a center cap and Grade 5 stainless hardware, so it looks right on a detailed build. Match the wheel finish to your body and bumper color scheme.
