Jaguar performance modifications, custom ECU and TCU (transmission )tuning ,Pulley and intake Upgrades for XKR XFR XK XF XE F-Type F- Pace, Range Rover

Can you improve on perfection? We like to think so.
Our newest crank supercharger pulley versions now come standard with an anti-slip surface — the same performance-focused design used on our upper pulleys!
Even better, each pulley is engineered as a direct-fit version for the specific factory pulley application. No spacers. No washers. No “make it work” shortcuts.
Just a clean, precise fit with better grip, better consistency, and the same previous machining & attention to detail we put into every AlphaJag performance upgrade! Enjoy!!
