VE VF Holden Commodore LS3 L76 L77 L98 V8 Improved Racing Sump Oil Pan Baffle

The GM LS family small blocks are prone to oil starvation at high Gs, especially at higher RPMs where oil aeration and windage is more prevalent. Proper oil pan baffling is critical for improving oil control and reducing oil starvation in these engines.

Improved Racing's baffles provide very effective, track-proven protection against oil starvation for road racing, drifting, autocross, drag racing and even off-roading and rock crawling. The baffle uses trap doors to keep oil around the pickup tube and provides vastly improved oil control over the stock baffle. This baffle is sufficient to prevent oil pressure drops at up to 1.4 sustained lateral G's in most vehicles.

Features and Benefits

• Track-proven to prevent oil starvation at up to 1.4 sustained lateral G's
• Directional trap door baffling completely encloses the oil pump pickup for maximum protection against oil starvation at high Gs
• 100% bolt in, no welding necessary. This is a direct bolt-in replacement for the stock steel baffle in the stock oil pan
• Baffle plate with drain-back slots help accelerate return of oil to the bottom of the sump while also preventing oil slosh and reducing oil consumption
• Reduces the risk of oil starvation when oil levels are low
• Works with the factory cast aluminum oil pan, which is considered a structural part of the engine block and is less prone to failure or leaking than aftermarket sheet metal pans
• Light-weight aluminum construction
• Solid body aircraft rivets employed for securing trap doors
• 12 Month Warranty
• Made in the USA
