Some may say they are only valve stem caps, but honestly…they are far more. The quality from JD Customs is everything people have been talking about. Decided to dip my toe into the burnt titanium water that JDC offers, and now I’m buying a snorkel. This certainly will not be my last purchase.
These look much better than the stainless bolts that come on Airlift struts and hold tight after use. A great upgrade!
Work of art! It’s actually kind of breathtaking when you open the box.
Thank you Paul, for helping me put with this badge. This badge looks amazing and I love it underneath of my Subaru Sti.
Absolutely perfect in every way possible definitely a perfect touch to the controller
As always you guys killed it with the design and quality and customer service delivery was super quick what else can I say other then I love everything I’ve gotten from JDC
The power steering cap is a must-have piece for your Mitsubishi. The quality of the lettering and etching is incredible. And shout out to the team who color the parts. I wanted a bare background and burnt lettering so that it would match my engine bay theme and colors. They typically don’t do that, but they went out of their way to laser etch around the burnt lettering on top and polish the sides to remove the burnt coloring. They did this for all of my other parts too! I can’t thank y'all enough! I highly recommend JDC’s products!
It’s beautiful 😍, I’d buy it over and over, JDC always with the best titanium parts and ideas.

2024–2026 Ford Mustang Engine Components FAQ's
Please read our FAQs page to find out more.
What internal upgrades are common past bolt‑ons on the Gen‑4 Coyote/EcoBoost?
Forged rods/pistons, upgraded bearings, and head studs support higher boost or RPM. Pair with valve springs and oiling upgrades for sustained track use.
Are cam upgrades worthwhile on the 5.0?
A well‑matched cam broadens the powerband with supporting springs and calibration—expect mid‑range and top‑end gains when combined with intake/exhaust flow.
Should I refresh timing components on higher‑mileage or high‑RPM builds?
Inspect chains, guides, and tensioners during builds. Fresh components reduce risk under increased spring pressure and heat cycles.
