Riaction TPU Coilovers for 2012-2016 Volkswagen Passat (B6/B7)

Product Details

The Riaction TPU Coilovers for the 2012-2016 Volkswagen Passat B6/B7 bring Riaction's digressive damper technology to the Volkswagen Passat, engineered for drivers who prioritize high-speed control, flatter cornering, and sharper response than a linear coilover can deliver. Each TPU set is built-to-order so valving and spring selection are matched to your exact Volkswagen Passat application, with the same 32-level damping adjustment and full-length ride-height range you'd expect from the Riaction platform. For B6 owners chasing a track-focused setup without giving up street composure, this B6 coilover kit bridges the gap between daily driver and weekend warrior.

Digressive pistons give the TPU a higher initial damping rate at low shaft speeds (body roll, weight transfer) and relax over big inputs (potholes, curb strikes), so you get better control without the harshness of a stiffer linear tune. Riaction coilovers for the 2012-2016 Volkswagen Passat ship fully rebuildable and backed by a 2-year warranty, making the TPU a long-term investment for enthusiasts serious about their Passat setup.

TPU vs GT1 — Which Is Right for You?

Both kits share the same 52mm monotube damper body, 32 levels of damping, full-length ride-height adjustment, and spring rates. The difference is in how the damper reacts:

The GT1 uses a linear piston — good low-speed control for body roll, turn-in, and weight transfer, with damping that follows a predictable curve through bumps. That balance makes it the right call for street, canyon, and occasional track days. The TPU runs a digressive piston that sharpens low-speed response with higher initial resistance for flatter cornering, then softens at higher shaft velocities — a blow-off behavior that relieves harshness over potholes, curbs, and expansion joints. The TPU is built for track-focused driving, autocross, and aggressive street use where you want the extra bite under load.

Short version: choose GT1 if you want the best daily-street-track balance — typically in stock and ship-ready. Choose TPU if you want tighter response under load and don't mind the lead time on a built-to-order digressive tune.
