XYZ Racing Pro Rally Coilovers — Infiniti QX70 (S51) 4WD 2013-2017

The S51 QX70 is an unusual rally base – a 2.1-tonne, V6-powered crossover with a longitudinal layout, proper rear-biased 4WD, and a wheelbase that’s actually closer to a competition stage car than its FX predecessor lets on. What it doesn’t have, in factory trim, is the wheel travel, the damping authority, or the chassis support to survive a gravel stage at pace. That’s the gap this kit is built to close.

The XYZ Racing Pro Rally coilover for the Infiniti QX70 (S51) 4WD is a competition-grade gravel and snow setup intended for crews running modified bodywork – arch clearance, strengthened mounting points, the works. This is the second of XYZ’s two rally tiers, and it assumes the car has already been built around it rather than the other way round.

What this coilover does for your 2013-2017 Infiniti QX70 (S51) 4WD

Rally damping on a heavy 4WD platform is a different problem to circuit damping. The QX70’s mass wants to keep moving long after the surface has changed, and a road-spec strut simply runs out of stroke on the first proper compression. The Pro Rally kit replaces that with long-travel, high-flow damping designed to absorb landings, kerb-strikes and washboard gravel without bottoming or fading on a long stage. Ride height comes up – not down – to clear ruts and protect the sump. On snow and loose surfaces you get a chassis that stays planted under throttle from the rear axle, with enough compliance to keep the front tyres biting through camber changes. Brake stability improves out of all recognition, because the dampers are finally controlling the weight transfer rather than reacting to it.

About the Pro Rally coilover

XYZ Racing splits its rally range into two distinct programmes: an amateur tier engineered to bolt to the original chassis, and this Pro Rally tier engineered to fit a car that has been modified to receive it. The Pro Rally is the second of those – the competition variant, sold on the assumption the bodyshell has been opened up, reinforced or otherwise prepared for rally-spec geometry and travel. Construction is built around the demands of gravel and snow competition: high-flow valving for sustained large-stroke work, robust seals to keep grit and water out of the damper body, and ride-height geometry that prioritises ground clearance over kerb weight reduction. The character is unambiguously competition – it is not a fast-road coilover with longer springs.

Fitment for the Infiniti QX70 (2013-2017)

This kit is matched to the S51 QX70 in 4WD form across the 2013-2017 production run. Confirm your chassis code reads S51 and that the car is the all-wheel-drive variant before ordering, and check that your bodywork preparation matches the Pro Rally installation requirements rather than the amateur-tier (direct-fit) coilover.
