BMW E38 rear coil spring BILSTEIN-36-153947 for 728i 730i 740i 750i 725tds

Direct-fit Bilstein B3 rear coil spring for BMW E38 (1994-2001) - no cutting, no welding, no compromises. Fits all UK-spec E38 variants named: 728i, 730i, 740i, 750i and 725tds.

• Hot-set chrome vanadium steel - resists sag and corrosion far better than worn OE units
• Factory-correct spring rate - restores original ride height, handling balance and daily-driver comfort
• No fitment guesswork - designed as a precise OE geometry match, not a generic 'sport' spring

Not a stage 2 track kit. Not a lowered spring. Just the right part, properly made, to fix sagging rear axle height and vague low-speed handling - cleanly and reliably.
