Keeping it simple, SPL Parts makes bad ass suspension components. Everything they make is built and sourced right here in the USA. A combination of titanium, 2024 & 6061 aluminum can be found throughout SPL's line of suspension parts.
Want to know a bit more? When you're after absolutely precise alignment settings, and settings that are going to stick through abuse - knowing your components are made through CNC, using spherical bearings, and TIG welded by hand is the assurance you want.
SPL Parts define heavy duty and it's who we turn to for all of our hard parts when upgrading the suspension.
