MGC Series™ (Maximum Ground Clearance) A arms

CAD developed for the optimal shock to A arm motion ratio. These suspension components are for the serious motocross, cross country and desert racers. Whether it’s a rut, rock or a stump this design clearly has advantages over the normal conventional straight A arm and the “Gull Wing” design.

They are constructed with only the highest quality 4130 chromoly alloy steel tubing products available. The CNC parts are checked and re checked for accuracy before the manufacturing process occurs. The gussets are all CNC laser cut for an identical accuracy. In addition they are also engineered for exact critical placement locations on our A arms. All our products are TIG welded by professional welders with many years of experience in the motorsport industry.

Most models are supplied with our signature…. white delrin bushing with a built-in groove for a supplied O-ring to be installed, sealing the pivot points in the frame. All models except for the Yamaha’s are supplied with inner steel pivot sleeve acting as a bearing. The Yamaha uses their stock ones with the OEM grease caps. The XC racing arms have a thicker wall in the front tubes to insure the integrity of the arm. This added feature is at no additional cost to the customer.

After the powder coating and or chrome is complete, our last step before packaging is reaming the delrin bushings. As simple as it may sound most other manufactures leave this part of the process out. After the Delrin bushings are pressed into the pivot tubes we run a reamer through the bushings. This opens the I.D eliminating the majority of the drag when you tighten you’re A arms on the frame, giving you the right flow they need for a smooth travel.

Our MGC Series A arms do not require adjusting the caster. This accurate angle was engineered into the design of the A arm for best possible performance. However, if you prefer, ATV Four Play, LLC offers this as an added option utilizing a HD, 3- piece, Teflon®/Kevlar® rod end for adjusting your own caster requirement. Please note our new GEN. II MGC for the TRX 450R has this option as a standard for this product.
