Product Details
BC Racing ZR Series Coilovers for the 1989-1994 Nissan 240SX (S13) deliver the deepest damping adjustability in BC Racing's lineup, with Swift Springs included standard and three axes of independent tuning for competitive track programs. Every kit is extensively tested on the 240SX S13 chassis and refined until it balances ride quality with performance — the reason 240SX coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.
ZR Series kits use an inverted mono-tube damper with a linear twin-piston design, feeding three independent adjustment circuits. Swift Springs come standard — not as an upgrade — and the kit is race-tuned out of the box. BC Racing takes pride in choosing spring rates and damper valving that balance comfort and performance — you never end up with the oversprung, harsh-riding kit some brands ship as their only option. Drivers who want to deviate from the factory setup can order Swift Springs, custom spring rates, and custom valving at checkout; BC will re-valve the dampers to match whatever you specify, a level of customization most brands reserve for their top-tier race kits.
BC Racing has been manufacturing adjustable coilovers since 2004 and is one of the most popular coilover brands in the automotive tuning industry for a reason: competitive pricing, deep customization, proven reliability, and a fully rebuildable damper design that lasts years instead of seasons. These 240SX coilovers arrive tuned for the S13 chassis and ready to bolt in — no break-in period, no guessing at setup. Every kit ships with a 2-year manufacturer warranty, lifetime access to BC service parts (pistons, seals, shafts — no unit replacement required when it's time for a rebuild), and in-house tech support from both BC Racing and the Springrates team.
