Built To Be Touched is PP-04 in the Piston Pin-ups series.The connecting rod lives between extremes. It translates combustion into motion, pressure into rotation, thousands of times per minute. Every surface, every curve, every finish exists for a reason. It is a component defined as much by feel as by measurement.PP-04 focuses on the rod as an object of contact and consequence. The design pairs piston parts with a 1940s-inspired pin-up illustration, echoing a time when craftsmanship invited interaction and machines were understood through hands as much as drawings. The slogan Built to Be Touched speaks to both form and function—because in mechanical reality, tolerances are checked, surfaces are felt, and trust is earned through contact.This T-shirt is part of the Piston Pin-ups collection, a numbered series of eight designs released individually over time. Each piece highlights a specific engine component, forming a deliberate and collectible sequence for those who value engineering detail and mechanical honesty. Created for those who know that performance begins long before the engine runs—and that understanding starts with touch. PP-04 / ROD Piston Pin-ups — Built To Be Touched
