Big-Rigs Shock Absorbing Caster Forks for Rear-Wheel Drive Power Chairs

• Fits wheels with diameter sizes of 6x2, 7x2, and 8x2

• Big Rigs were designed to replace our very popular BULLFROG (all hard points are the same).
• Suspension fork uses a "hinge" design encapsulating a high energy-absorbing polyurethane cylinder. The cylinder will flex to eliminate vibration and soften bumps by absorbing the force created when the front wheel strikes an object.
• 3 inches of arch travel allowing the front wheel to lift back, up and over obstacles and prevent pitching
• Approved HCFA codes E1018R and E1018L
• Will not change the wheelchair's foot to floor dimensions.
• Custom stem bolt lengths are available to accommodate a variety of geometry requirements
• Fits wheels with diameter sizes of 6x2, 7x2, and 8x2.
• All forks CNC machined of 6061-T6 aluminum
• 1144 steel stress-proof clear zinc plated flanged studs (stem bolts) available in both metric and imperial measurements.
• 1144 steel stress-proof stainless steel hinge and axle pins.
• Bronze bushings within the hinge improves pivoting abilities.
• Lifetime limited warranty on fork with exception of urethane polymer cylinder. Under normal use, the polymer component holds its shock absorbing ability for 5 to 7 years. Replacement polymers are readily available.
