FAQ

Does it require professional painting?
No. The splitter comes with high-quality gloss black finish ready to install.

Can I install it myself?
Yes, with basic tools. Installation is straightforward, though we recommend visiting a workshop to ensure maximum adhesion and avoid misalignment.

Why ABS instead of fibreglass?
Injection-moulded ABS absorbs impacts from small stones and vibrations better, without cracking like cheap fibreglass after a few months of use.
