The H&R 29955 is a sport lowering spring set for 1993–1999 Volvo 850 and V70 wagons with front-wheel drive and conventional, non-self-leveling rear suspension. Owners on user forums say H&R sport springs give a lower, purposeful stance with a stiffer, more controlled feel than stock, which is why enthusiasts pick them for a 850 wagon handling upgrade. Lowering the center of gravity also reduces body roll in quick direction changes, so the gain is most noticeable on a heavy wagon that leans through corners. Because the springs change ride height without replacing the dampers, owners on user forums warn that stock shocks wear out faster once lowered, so budget for shocks or struts at the same time for the best value over a cheaper generic set.
Rear installation is manageable at home. Owners on user forums describe raising the car to full droop, loosening the 15mm spring-seat nut and the two shock mount bolts reached from the trunk, and lowering the seat to free the coil, with some reporting no spring compressor was needed. Mark the spring's end positions before removal so the new coil seats correctly, and clean rust from the threads first. Confirm the drop height and fitment against the manufacturer's install documentation before ordering, because published drop figures vary between sources. This listing is for the non-self-leveling version only; self-leveling rear suspension needs a different kit.
No. This part is specified for non-self-leveling rear suspension only. Owners on user forums note that self-leveling rear units rely on the shock to carry much of the car's weight, so self-leveling cars need a different setup.
Owners on user forums report that lowering springs on stock shocks and struts wear out more quickly, and many recommend upgraded dampers at the same time. Installing new shocks alongside the springs also saves labor.
Details vary. Some owners on user forums say the rear springs can be swapped by lowering the suspension to full drop without a compressor, while others used an internal compressor to position the spring while the control arm stayed bolted in place.
Rear spring replacement on these wagons is a moderate, driveway-friendly job for a home mechanic with a floor jack, jack stands, a 15mm socket and ratchet, and a pry bar for stubborn parts. Owners on user forums suggest soaking the nut and shock bolts with penetrating oil before loosening them. Be ready for the weight of the old coil, which owners estimate at roughly 8–10 lb, and support the car securely before removing anything. Front and rear installation details were not confirmed from the manufacturer's install sheet, so check the included instructions before starting.
