Atomic Billet Main Cap Girdle – Ford Barra 6-Cyl | 10mm or 16mm | DOHC & SOHC | High Tensile Steel
Description: As Barra-powered builds push beyond 400kW at the tyres, the stock bottom-end starts to show its limits. Main caps begin to “walk” on the block, throwing off crankshaft alignment and accelerating bearing wear — sometimes catastrophically.
The Atomic Billet Main Cap Girdle is precision laser-cut from billet high-tensile steel and CNC-machined to exact tolerances. It’s designed to tie all 7 main caps together, adding critical structural integrity to the bottom-end of your Ford BA–FG DOHC or SOHC 6-cylinder engine.
Available in 10mm or 16mm thickness, and compatible with both standard and billet main caps, this girdle installs without needing to modify your sump or clearance your conrods — unlike cheap, copycat alternatives. If you're chasing reliable performance at 400kW+ or building for 1000+hp, this is an essential reinforcement.
✅ Key Features:
✅ Suits Ford BA–FG 6-cyl engines – DOHC & SOHC ✅ Available in 10mm or 16mm thick high-tensile billet steel ✅ Works with standard OR billet main caps ✅ Laser cut and CNC machined – superior fit and finish ✅ Ties all 7 main caps together to prevent cap walk ✅ Maintains bearing alignment and crankshaft integrity under extreme load ✅ No sump notching or welding required – fits without mods ✅ Provides minimum 4mm clearance to conrod bolts ✅ Counterbored holes allow proper bolt engagement into the block ✅ Fits with OEM or aftermarket main studs/bolts
🛠️ Why Choose the Atomic Girdle Over Cheaper Copies?

1x Atomic Billet Steel Main Cap Girdle
Choice of 10mm or 16mm thickness
