Bumper Extension IMCA 4in

The BERT TRANSMISSIONS Bumper Extension IMCA 4in is a specialized jack saddle extension engineered for IMCA-class racing vehicles that rely on pneumatic air jacks for pit-stop service. This aluminum-constructed extension mounts between the air jack saddle and the vehicle's bumper contact point, extending the effective reach by 4 inches—a critical dimension for drivers working with IMCA-regulation bumper geometries and frame heights. The natural aluminum finish resists corrosion while maintaining the lightweight characteristics essential in competitive motorsports where unsprung weight reduction directly impacts suspension performance and lap times.

Weighing just 1.6 pounds, this bumper extension preserves the efficiency of air jack systems by minimizing added rotational mass at the jack saddle interface. The 4-inch extension length accommodates frame rails and bumper profiles typical of IMCA stock cars, dirt modifieds, and other classes where bumper ride height and frame geometry are controlled by tech specifications. Proper saddle reach prevents load concentration on narrow contact points, distributing lifting force across a wider bumper surface and reducing the risk of component deformation during rapid pit cycles. The compact footprint (4.25 x 2.8 x 7.45 inches) stores efficiently in a pit box and integrates seamlessly with standard BERT air jack saddle systems.

This extension is purpose-built for IMCA racers, short-track competitors, and pit crews operating under sanctioned bumper specifications who require precision jacking equipment rated for repeated high-cycle use. IMCA racing demands consistent, fast lifting cycles across multiple pit stops per event—conditions that require properly engineered jack saddle geometry to maintain load stability and operator safety. The BERT TRANSMISSIONS Bumper Extension IMCA 4in addresses the specific dimensional requirements of IMCA-regulation bumpers, ensuring compatibility with air jack systems engineered for this class while eliminating the need for improvised or undersized saddle adapters.
