Give us a quick call at 636-429-7020 or message us to schedule a visit — we’ll make sure the parts are ready when you arrive.

How do I know if this part fits my vehicle?

Unsure if it’ll fit? No problem — that’s what we’re here for. Send us your vehicle’s year, make, and model, and we’ll verify fitment before you order. We can also point you toward compatible upgrades or supporting parts if needed.

What if I need to return a product or it’s defective?

Most unused items can be returned within 30 days in their original packaging. Some products are covered by a manufacturer’s warranty as well. If something arrives damaged or doesn’t meet your expectations, just let us know — we’ll help you get it replaced, refunded, or repaired. (Tracking updates are also emailed automatically once your order ships.)

What's the lead time on custom or fabricated parts?

Many of our parts are built to order — especially fabricated or performance components. These can take additional time to produce before shipping. Lead times vary by manufacturer and demand, but we’ll always keep you updated along the way. If you’re working on a tight schedule, reach out before ordering at 636-429-7020 and we’ll confirm current availability or estimated ship dates.

Description

Mishimoto is proud to release a direct-fit silicone boot kit with DuraCoreâ„¢ technology designed specifically for the 2017-2019 Chevrolet/GMC 6.6L L5P Duramax. Mishimoto DuraCoreâ„¢ technology is a synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCoreâ„¢ provides superior resistance to heat, pressure, fuel, and oil. This effectively increases the life of our boots by preventing leaks and blowouts. To add even more reliability, these couplers feature stainless-steel reinforcing rings to prevent expansion under high pressure that may result in a blowout and lost boost pressure. This kit also includes Mishimoto stainless-steel constant-tension T-bolt clamps for a reliable and consistent seal. As with all our products, this boot kit is protected by the Mishimoto Lifetime Warranty.
