• Replaces all 14 rocker cover fasteners. Direct bolt-in, no modifications.
• Titanium burnt blue finish. Heat treatment creates controlled oxidation on the surface, which is where the iridescent blue comes from.
• Anodised washers in your choice of colour. Blue on blue for a coordinated look, or gold or red if you want the contrast.
• Corrosion resistant. The burnt finish holds up about as well as plain stainless.
• Cosmetic. Fit and finish, nothing else. If you want power, this is the wrong page.

• Holden Rodeo RA7. 4JJ1-TC 3.0L, 2007 to 2008.
• Holden Colorado RC. 4JJ1-TC 3.0L, 2008 to 2012.
• Isuzu D-MAX. 4JJ1-TC 3.0L, 2006 to 2012.
• Covers. Suits HPD alloy rocker covers and OEM factory covers alike.

Count the bolts across the front of your rocker cover. This set is for the Euro 2 and Euro 3 4JJ1 cover: 3 bolts across the front, 14 bolts in total. The Euro 4 4JJ1 and the 4JJ3 use a different cover: 4 bolts across the front, 15 in total, and that one needs the HPD 4JJ1 Euro 4 and 4JJ3 Ti Burnt Blue Bolt Set. The two kits are not interchangeable, so count before you order.

• 14 x HPD Ti burnt blue stainless rocker cover bolts. Heat-treated titanium finish.
• 14 x HPD anodised washers. One colour per kit, selected at checkout.

Washer colours commonly available are blue, red, gold, purple and black. Availability moves around, so ask us if you need a specific colour confirmed before you order. Each kit ships with 14 matching washers.

• This listing. Euro 2 and Euro 3 4JJ1-TC. 3 bolts across the front, 14 total. Rodeo RA7, Colorado RC and D-MAX as listed above.
• Euro 4 4JJ1 and all 4JJ3. 4 bolts across the front, 15 total, and the kit includes machined spacers. Use the Euro 4 and 4JJ3 Ti Burnt Blue Bolt Set.
• Same fitment, plain stainless finish. If burnt blue is not your thing, the HPD 4JJ1 Bolt and Washer Set is the same 14 bolts and 14 washers with a polished stainless finish. Choose on looks, both are HPD.
• Adding a cover. See the HPD 4JJ1 Aluminium Rocker Cover.

• No modification required. Remove the old bolts, fit the HPD bolts with the washers.
• No special tools. A standard socket set is enough.
• Follow the factory rocker cover torque specification. Overtightening causes gasket damage and leaks.
• No thread sealant. Rocker cover bolts do not normally need it. Use a proper gasket.
• Heat-treated steel into an alloy cover is fine. The washers spread the load and keep the two metals apart.

• Free express shipping Australia-wide, including rural and remote.
• Dispatch: in stock orders placed before 2 PM AEST on a business day go out the same day.
• Buy now, pay later: Afterpay, Humm, Klarna and Zip. All major credit cards accepted.

This is a cosmetic kit. It will not add power and it will not fix an oil leak. If your cover is weeping, the gasket and grommets are the job.

Pick your washer colour carefully. Returns need the parts unused and in the original packaging, and a change of mind on colour is not a fault. If you are not sure what suits your engine bay, message us before you buy.

Q: How many bolts are in the kit?

A: 14 bolts and 14 washers. That is the full fastener count for a Euro 2 or Euro 3 4JJ1 rocker cover, which has 3 bolts across the front.

Q: How do I tell which cover I have?

A: Count the bolts across the front edge. Three across the front is this kit. Four across the front is the Euro 4 or 4JJ3 cover, 15 bolts total, and it needs the other kit linked above.

Q: What is a Ti burnt blue finish?

A: Controlled heat treatment that oxidises the surface of the metal and leaves an iridescent blue. It is durable and corrosion resistant, and every bolt comes out slightly different, which is part of the look.

Q: How does it compare to the polished stainless kit?

A: Finish only. Burnt blue is the standout look and coordinates with other titanium hardware. Polished stainless is the classic chrome look. Both are genuine HPD with anodised washers.

Q: Do they fit HPD alloy rocker covers?

A: Yes, and factory covers too.

Q: Will the burnt blue fade?

A: It may shift a little under long-term engine bay heat, as any heat-treated finish does. The bolts stay functional and corrosion resistant.

Q: Can I mix washer colours?

A: Each kit ships with 14 matching washers in one colour. Contact us if you want a custom mix.

Q: Are these as strong as the factory bolts?

A: They do the same job to the same standard. The gain is corrosion resistance and appearance, not clamping force.
