Billet Rear Camber Links for Nissan 370Z, Infiniti G35/G37/Q40, and Nissan Z with SPL RLL Z34B
The SPL RLL Z34B delivers wide-range rear camber adjustment for the Nissan 370Z Z34, Infiniti G35 V35, Infiniti G37 V36, Infiniti Q40, and Nissan Z RZ34 using a billet 6061-T6 aluminum arm design engineered to provide clearance for sway bar end links on coilover and lowered configurations. The SPL RLL Z34B uses a slotted arm with 360-degree rotating clamps and a gun-drilled 4130 chromoly double adjuster for precise, jam-nut-free camber adjustment on street and track builds. PTFE-lined FK rod ends eliminate bushing compliance for consistent rear alignment under load. Note: does not fit Convertible models.

Frequently Asked Questions
Does the SPL RLL Z34B fit the 370Z Roadster convertible?
No. The SPL RLL Z34B does not fit the 370Z Roadster convertible models. It is designed for coupe and non-convertible G37 and G35 variants. Please verify your specific body style before ordering.
How much camber adjustment does the SPL RLL Z34B provide?
The double adjuster and 360-degree rotating clamp deliver a wide range of rear camber adjustment beyond OEM limits, accommodating both mild alignment correction on lowered street builds and aggressive negative camber settings for track use on the 370Z, G35, G37, and Nissan Z platforms.
Will the SPL RLL Z34B clear the sway bar end link on my coilover setup?
Yes. The billet arm geometry was specifically designed to provide sway bar end link clearance for true coilover conversions on the 370Z and G37 platform, where the dogbone-style arm can create clearance problems.
Is the SPL RLL Z34B street legal?
Yes. The SPL RLL Z34B is a suspension alignment component and does not affect emissions or safety systems. It is appropriate for street use in all 50 states. A professional alignment is required after installation.
Does the SPL RLL Z34B also fit the 2023+ Nissan Z?
Yes. The SPL RLL Z34B is confirmed to fit 2023-2024 Nissan Z Sport, Performance, and Proto Spec trims, which share the RZ34 platform with compatible rear suspension geometry.
How do I adjust camber without jam nuts?
Loosen the titanium clamp hardware, rotate the 4130 chromoly double adjuster to the desired arm length, then retighten. No jam nuts are needed, and adjustment can be done on the car.
What companion products does SPL Parts offer for the 370Z rear alignment?
Pair the SPL RLL Z34B with SPL RTA Z34 rear toe arms, SPL RML Z34 rear mid links, and SPL EL Z34 eccentric lockout kit for a complete rear alignment system with zero-slip adjustment on the 370Z and G37.
Does installing the SPL RLL Z34B void my factory warranty?
Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your powertrain warranty solely because you installed an aftermarket suspension component, unless they can demonstrate the part directly caused a failure. Consult your dealer for your specific situation.
Installation Instructions
- Safely raise and support the vehicle on jack stands; remove the rear wheels for access.
- Record the current rear camber measurement or photograph the OEM arm position.
- Remove the OEM rear lower camber link mounting hardware and set the arm aside.
- Place the SPL RLL Z34B next to the OEM arm; pre-set the double adjuster to match OEM center-to-center length with equal thread engagement on both ends.
- Install the SPL RLL Z34B with OEM or supplied hardware; snug only until the vehicle is at ride height.
- Lower the vehicle to ride height and torque all mounting hardware to factory specification.
- Tighten the 360-degree rotating clamps with the titanium Allen screws to lock the adjuster in place.
- Have the vehicle professionally aligned on a four-wheel alignment rack before driving.

Control Arms
Control arms are the key suspension linkages that connect the wheel hub and knuckle assembly to the vehicle frame, controlling wheel travel through both compression and droop cycles. Worn OEM control arms with loose ball joints or deteriorated bushings cause vague steering, tire wear, and handling inconsistency that only go away with replacement or upgrade.Popular UpgradesTubular steel upper control arms for lifted trucks and SUVs are the most popular upgrade in the control arm category, correcting the geometry compromised by a suspension lift and restoring proper caster angle and ball joint centering. Adjustable upper control arms allow alignment angles like caster and camber to be dialed in precisely after a lift or lowering modification. Replacement lower control arms with polyurethane or solid aluminum bushings improve response and longevity compared to worn OEM rubber mounts.Why do I need new control arms after a lift kit?A suspension lift changes the angle at which the OEM upp...
