1. TDCi Gear Stick in Satin Black

TDCi Gear Stick in Satin Black

For Puma TDCi Defender owners (2007–2016), the factory gear lever can feel vague and tired, especially after years of use. Our billet aluminium gear stick, CNC-machined in-house and finished in satin black, delivers sharper shifting and an immediate sense of quality.

• Why upgrade: Improves shift feel and adds premium styling.
• Perfect for: Drivers who want everyday usability to match Defender toughness.
• Added value: Designed and tested for the Defender, not a universal part.

2. Window Blocks in Satin Black

Window Blocks in Satin Black (pair)

Defender rear windows are a common weak point for thieves. Our billet aluminium window blocks reinforce them from the inside, preventing opportunists from forcing them open.

• Why upgrade: Discreet but highly effective security upgrade.
• Perfect for: Anyone carrying tools, kit, or personal items in the rear.
• Added value: Simple to fit, satin black finish blends into the interior.

3. Wing Top Vents in Satin Black

Wing Top Vents in Satin Black

The original Defender wing vents are functional, but often prone to rust, corrosion and damage. Our billet aluminium replacements are precision machined and finished in satin black for durability and style.

• Why upgrade: Tougher, smarter, and longer-lasting than OEM plastic or steel vents.
• Perfect for: Owners who want a subtle visual upgrade with practical benefits.
• Added value: Matches perfectly with other satin black Optimill upgrades.

4. Slimline Quick Release Boss

Slimline Boss

One of our most exciting new arrivals is the Slimline Quick Release Boss. It’s compact, secure, and works seamlessly with our Quick Release Steering Boss kits.

• Why upgrade: Slimmer profile means improved driving position and steering feel.
• Perfect for: Defender drivers looking for added comfort without compromising security.
• Added value: Machined from billet aluminium, anodised for durability.

5. Security Hinges – refreshed finishes

Defender Security Hinges

We’ve refreshed our range of door and bonnet hinges, with new finishes and fitting options available. All our hinges are engineered from billet aluminium and feature anti-theft fixings.

• Why upgrade: Standard hinges are easy targets for thieves.
• Perfect for: Owners wanting to improve both looks and security.
• Added value: Satin black finish matches other Optimill upgrades.

Conclusion

From practical security to stylish refinements, these five new products reflect what Optimill does best: precision engineering that Defender owners can trust.

Whether you’re securing your Defender ahead of the darker months or treating yourself to an upgrade before Christmas, there’s something here for every owner.
