We didn’t survive two decades of high-horsepower chaos by playing it safe — and we’re not about to start now. To celebrate 20 years of going fast, being loud, and living slightly irresponsibly, we’re kicking off one of the biggest sales in Lethal Performance history. We’re talking up to 20% off the parts you actually want: exhausts, clutches, tuning tools, suspension, fuel systems, lighting, and more from top brands like McLeod, Thermal R&D, MRT, UPR, Corsa, and dozens more.
This mega sale runs through July, with new deals rolling out and expiring weekly — including Father’s Day and 4th of July specials. Whether you're chasing a new PB at the track, waking up your daily driver, or finally snagging that Lethal-exclusive setup you’ve been stalking for months… now’s the time. Check back often, shop fast, and don't miss your window — some of these deals will be gone before the burnout smoke clears.

Those tags are live and tied to the calendar. “Coming Soon” means the deal kicks in within 3 days. “Ends Soon” means you’ve got less than 48 hours to snag it before it’s gone.
We take all major credit cards, PayPal, and even Affirm financing — because going fast now and paying later is the Lethal way.
We try and keep a large inventory but we can't stock everything. If there is a delay we'll reach out once you place the order to keep you updated on when to expect your goodies.
At Lethal Performance, we specialize in Mustang, F-150, Bronco, and Explorer ST upgrades. From fuel systems to tuning devices, our curated brands include Whipple, McLeod, Thermal R&D, and more — all backed by 20 years of racing, wrenching, and winning.
