Shock caps take a beating on 4S trucks. Cross-thread one during a rebuild, crack a hex on a hard landing, or wear the sealing face until it weeps oil, and you've got a shock that won't hold pressure. ARA330671 is Arrma's genuine composite replacement pair, supplied with fresh O-rings so you get a proper seal rather than reusing a flattened one.

Worth keeping a set on the shelf if you rebuild shocks regularly — the O-rings are the part that actually fails, and they're rarely worth reusing once they've been compressed.

Key Features

• Genuine Arrma replacement shock caps
• Tough composite material for crash resistance and long-lasting performance
• Precision manufactured for consistent fit to your shock bodies
• O-rings included for a leak-free seal between cap and shock body
• Spare part for shock sets ARA330679 and ARA330680

What's in the Box

2 × Shock Cap
2 × O-ring (15 × 2mm)

Needed to Complete

Caps and O-rings only. Shock bodies, shafts, pistons, springs and shock oil are not included. If you're servicing shocks, you'll want shock oil on hand — see the ARA330674 aluminium (aluminum) shock body if the body itself is damaged.
