The Seat Mount Spacer Kit Upper from ALLSTAR PERFORMANCE is an essential component for custom vehicle seating installations, particularly in race cars, hot rods, and heavily modified street vehicles. This spacer kit addresses a common challenge faced by automotive enthusiasts and fabricators: achieving proper seat geometry and driver positioning when upgrading to racing seats or relocating stock seating. Whether you're building a dedicated track car or fine-tuning your daily driver's ergonomics, this upper spacer kit provides the precise adjustment needed to clear custom floor pans, roll cages, or modified chassis components while maintaining safety and comfort.

Manufactured by ALLSTAR PERFORMANCE, a trusted name in competition and street performance, this spacer kit is engineered to integrate seamlessly with standard seat mounting systems. The upper spacer design allows vertical and lateral seat positioning adjustments without compromising structural integrity or load distribution. At just 1.48 lbs, the kit remains lightweight—critical for performance builds where every ounce matters—while maintaining rigid support for driver retention and safety harness geometry. The compact profile (4.15 x 1 x 12.05 inches) ensures compatibility with a wide range of vehicle platforms and seat bracket configurations, making installation straightforward for experienced fabricators and shops.

This kit benefits drift competitors, autocross drivers, road course racers, and weekend warriors who demand precision seat mounting in modified vehicles. Installation typically requires basic hand tools and familiarity with seat bracket removal; professional installation is recommended to ensure safety harness mounting angles and crash safety compliance. The Seat Mount Spacer Kit Upper works in conjunction with lower spacer kits and OEM or aftermarket seat brackets, offering modularity that allows builders to achieve exact driver positioning. Always verify fitment with your specific vehicle platform and seat model before purchase, and ensure all mounting hardware is rated for your weight class and intended use.
