Brief Summary & Key Benefits

Our Lift Kits deliver extra ground clearance, improved approach/departure angles and predictable handling on and off the road. The range covers A-arm spacers, spring spacers, body lift puck sets and +2" HD lift kits. These solutions aim to retain OEM-like drivability while adding space for tyres and travel. Typical applications include Jeep Grand Cherokee WJ/WG builds for touring and light off-road.

Technical Basics

Different lift methods affect different parts of the vehicle. A +2" HD lift kit commonly includes reinforced fixings and longer damper hardware; a spring spacer sits above/below the coil, while a body lift puck raises the body relative to the frame. The A-arm spacer corrects front upper control arm geometry after a lift, keeping caster and camber in an adjustable window.

Materials: high-strength aluminium and steel with corrosion-resistant finishes. Some sets use heat- and oil-resistant polymer spacers to reduce NVH transfer to the cabin. Mating faces are precision-machined to maintain clamp load and specified Nm torque. Brand focus includes RS ULTIMATE, known for accurate fitment and durability.

Compatibility: most kits are platform- and year-specific. For the Jeep WJ/WG, check track width, brake hose length and propshaft angles. Critical notice: wheel alignment is mandatory after any lift to avoid uneven tyre wear and vague steering.

Selection Criteria

Height: for mixed daily/trail use, around +2" is a proven compromise; taller lifts may require longer sway-bar links and brake lines. Material: choose robust aluminium or steel for heavy off-road abuse; quality polymer spacers can be suitable for touring. If geometry correction is the priority, an A-arm spacer helps keep the ball joint within its ideal working range.

Heat/pressure & longevity: spring spacers see repeated heat cycles, so anodised aluminium or fibre-reinforced polymer is recommended. For body lift puck solutions, always use new high-grade fasteners and proper washers to distribute load.

Motorsport examples: in amateur rally or time attack events on mixed surfaces, a moderate lift frees wheel-arch clearance but raises the centre of gravity. Critical notice: with larger tyres, verify steering lock clearance; bump-stop tuning may be required.

Installation & Maintenance

Fitment tips: clean all mating faces; tighten hardware progressively in a cross pattern to the specified Nm. Re-check (re-torque) after 100–200 km on any +2" HD lift kit. Ensure brake lines, wiring and the propshaft are never taut at full droop.

Noise/leak prevention: use correct washers under body lift puck mounts to avoid point loading. When installing an A-arm spacer, protect the ball-joint boot and use medium-strength threadlocker on clean threads. Critical notice: book a professional alignment after installation and verify self-centring and brake-hose slack on a road test.

Checks: every 5–10k km inspect torque on fixings, look for bush cracking and monitor geometry settings. Rinse mud and salt after off-road use to slow corrosion. RS ULTIMATE parts have proven consistent performance, but always confirm fitment by exact model year/engine code.

FAQ

Q: Do I need longer brake lines for a +2" lift?
A: Usually not, but check at full droop; if tight, fit longer lines or relocation brackets.

Q: Will an A-arm spacer fix camber?
A: It helps keep the upper ball joint in range after a lift, making camber and caster easier to set.

Q: Does a body lift affect driveline angles?
A: Typically less than a suspension lift because it raises the body; still verify cable and hose lengths.

Q: What torque should I use?
A: Follow the manufacturer’s Nm specs for each fixing and re-torque after 100–200 km.

Q: What tyre size fits with +2"?
A: Commonly one size up fits, but check lock-to-lock clearance and arch liners for your platform.
