Compatible with both HPD alloy rocker covers and OEM factory rocker covers. Direct bolt-in replacement requiring no modifications.
Q: Are these genuine HPD bolts?
A: Yes! These are authentic Thai-imported HPD Special Parts hardware featuring genuine titanium burnt blue heat-treated finish with premium anodised washers. Not generic copies or imitations.
Q: What is "Ti Burnt Blue" finish?
A: Titanium burnt blue is a heat-treatment process that creates an iridescent blue finish on the metal surface. The distinctive appearance comes from controlled oxidation during heat treatment, creating a durable, corrosion-resistant finish with a unique rainbow-blue appearance.
Q: How does Ti burnt blue compare to regular stainless?
A: The titanium burnt finish offers a distinctive custom appearance that stands out in engine bays, while providing similar corrosion resistance to stainless steel. It's a premium aesthetic upgrade over standard polished or chrome hardware.
Q: Is this the same quality as HPD's other products?
A: Absolutely. HPD (High Performance Diesel) maintains consistent quality standards across their Thailand-manufactured product line. These bolts meet the same exacting specifications as all HPD Special Parts components.
Q: Do they fit HPD alloy rocker covers?
A: Yes — this kit is specifically designed to suit HPD alloy rocker covers, completing the premium HPD styling package. Also compatible with OEM factory rocker covers for instant visual upgrade.
Q: Will these fit my 4JJ1 engine?
A: If you have a Holden RA7 Rodeo (2007-2008), Holden Colorado RC (2008-2012), or Isuzu D-MAX (2006-2012) with the 4JJ1-TC 3.0L engine, yes — these are direct replacements.
Q: Is any modification required?
A: No modifications needed whatsoever. These are direct bolt-in replacements for factory hardware. Simply remove old bolts and install HPD bolts with included washers using proper torque specifications.
Q: Do I need special tools for installation?
A: No special tools required — a standard socket set is sufficient. Follow proper torque specifications when installing rocker cover bolts to prevent leaks or gasket damage.
Q: Do washers come in different colours?
A: Yes! Simply choose your preferred anodised washer colour from the product options when ordering. Multiple colours available to match your engine bay theme.
Q: What washer colours are available?
A: Common anodised colours include blue, red, gold, purple, black, and more. If you need a specific colour confirmed before ordering, contact us with your preference.
Q: Will the burnt blue finish fade?
A: The titanium burnt finish is durable and heat-resistant, but like all heat-treated finishes, it may show some colour variation over extended periods in high-heat engine bay environments. The bolts remain fully functional and corrosion-resistant regardless of minor colour changes.
Q: Can I mix washer colours?
A: Each kit comes with one colour of anodised washers (14 matching washers). If you want to create a custom multi-colour look, contact us and we can discuss custom combinations.
Q: How do I choose which washer colour to order?
A: Consider your existing engine bay colours — popular combinations include blue washers with Ti burnt bolts for a coordinated blue theme, or contrasting colours like gold or red washers for visual pop against the blue bolts.
Q: Are these as strong as factory bolts?
A: Yes — these HPD bolts meet or exceed factory strength specifications while providing superior corrosion resistance and premium appearance. Engineered specifically for 4JJ1 rocker cover applications.
Q: Will heat-treated bolts work with aluminium rocker covers?
A: Absolutely. The included washers help distribute load properly and prevent any material compatibility issues. Heat-treated steel bolts are commonly used with aluminium components in automotive applications.
Q: Do I need thread sealant on these bolts?
A: Follow the same installation procedures as your original rocker cover hardware. Typically, rocker cover bolts don't require thread sealant. Always use a proper rocker cover gasket and follow manufacturer torque specifications.
Q: What's the difference between this kit and the stainless HPD bolt kit?
A: The main difference is the finish. This kit features titanium burnt blue heat-treated bolts for a distinctive iridescent appearance, while the stainless kit has a polished chrome-like finish. Both are genuine HPD quality with anodised washers — choose based on your preferred aesthetic.
Q: Should I get Ti burnt or polished stainless?
A: Personal preference! Ti burnt blue offers a unique custom appearance that stands out and coordinates well with other titanium or burnt hardware. Polished stainless provides a classic chrome look. Both are premium quality.
Q: How quickly will this ship?
A: Most orders ship within 1-2 business days if in stock. Free express shipping applies to all Australian deliveries.
Q: Can I return these if I change my mind about the colour?
A: Items must be unused and in original packaging for returns. Please select your desired washer colour carefully before ordering. If you're unsure, contact us for colour advice before purchase.
Q: Do you ship to rural/remote areas?
A: Yes! Free express shipping covers all of Australia, including rural and remote locations.
Q: Can I use these with my stock rocker cover?
A: Absolutely! These bolts are a popular upgrade for factory rocker covers, adding custom styling without major modifications. Great way to enhance engine bay appearance on a budget.

A: Definitely. The titanium burnt finish and anodised washers create show-quality presentation. Popular choice for truck shows, 4x4 exhibitions, and pride-of-ownership builds.

A: Yes! The distinctive Ti burnt blue finish combined with colour-matched anodised washers creates a premium, custom appearance that elevates any engine bay presentation. Instant visual upgrade.
