Note: Installed pictures are of our 1 7/8" headers with 1" offset back motor mounts.

Note: "Due to older vehicle frame clearance headers are pulled in very tight, and require our spark plug wires".

Note: "For LS series engine swaps only" These do not work on standard SBC or BBC engines.

Note: If using a larger 4L80E or older Turbo 350/400 transmission the bellhousing ears may need to be trimmed for proper clearance.

Note: Confirm your vehicle is an A body chassis before purchasing. Some vehicle models did come in a G body application in earlier years. Will have fitment issues on an G Body Application.

For me the ball joints came bolted in on both upper control arm.
The also make it easier for future bushings replacements, by not being pressed fit. They also have grease ports to grease the bushings.
