The Texas Speed LT Low Profile Retrofit Oil Pan Kit is a cast aluminum swap pan for GM Gen V LT engines being installed in classic cars and trucks that need more oil pan clearance. Texas Speed designed it to fit a range of vehicles and swap combinations, describing it as providing maximum ground and K-member clearance while keeping the durability and reliability of the factory cast pans. This listing is the black finish version, manufacturer part number 81577BK.
The pan follows OE style fitment, retaining the factory oil filter mounting and sealing with OE style gaskets. It is sold as a complete kit with a wet sump baffle, an OE style pickup tube, plugs and gaskets. Texas Speed lists compatibility with the L83, L84 and L82 5.3L, the LT1, L86 and L87 6.2L and the LT4, which covers the common Gen V engines pulled for resto-mod swaps.

FAQ
What engines does the Texas Speed LT Low Profile Retrofit Oil Pan Kit fit?
Texas Speed lists this pan for GM Gen V LT engines including the L83, L84 and L82 5.3L, the LT1, L86 and L87 6.2L and the supercharged LT4. It is intended for LT engines being swapped into classic cars and trucks.
Is this pan vehicle specific?
No. The Texas Speed LT retrofit pan is a swap pan designed to fit a number of different vehicles and engine swap combinations rather than one factory application, so the chassis receiving the engine determines whether the clearance works.
What is included in the LT retrofit pan kit?
The complete kit includes the black cast aluminum low profile pan, a wet sump baffle, an OE style pickup tube, plugs and gaskets, so the pan can be installed without collecting separate pieces.
Does the pan keep the factory oil filter mounting?
Yes. The Texas Speed LT retrofit pan uses OE style fitment, retaining the factory oil filter mounting and sealing with OE style gaskets, so filter changes stay the same as on a stock Gen V engine.
What is the difference between the black and satin LT pans?
Only the finish. The black pan is part number 81577BK and the satin pan is 81577; both share the same cast aluminum low profile design, clearance and kit contents.
