SPL Parts 03-08 Nissan 350Z Rear Camber Links (Billet Version)

Billet Rear Camber Links for Nissan 350Z and Infiniti G35 with SPL RLL Z33B

The SPL RLL Z33B is the billet version of the SPL Parts rear camber link for the Nissan 350Z Z33 and Infiniti G35 V35, machined from 6061-T6 billet aluminum specifically to clear sway bar end links on lowered and coilover-equipped vehicles. The billet arm design with 360-degree rotating clamp and gun-drilled 4130 chromoly double adjuster delivers a wide range of rear camber adjustment for high performance street and race use. SPL RLL Z33B is designed for vehicles that have converted to true coilovers in the rear suspension position, where sway bar end link clearance becomes a concern. PTFE-lined FK rod ends eliminate bushing deflection for consistent, predictable rear alignment.

Frequently Asked Questions

Why is there a billet version of the 350Z camber link?
The SPL RLL Z33B billet version was designed for vehicles using true coilover conversions in the rear suspension, where the original dogbone-style arm can interfere with the sway bar end link. The billet arm geometry provides clearance for the end link while maintaining full camber adjustability.

How much camber adjustment does the SPL RLL Z33B provide?
The double adjuster and 360-degree rotating clamp deliver a wide range of rear camber adjustment beyond OEM limits, allowing both mild street correction and aggressive track-spec negative camber settings on the 350Z and G35 V35.

Does the SPL RLL Z33B fit both coupe and roadster 350Z models?
The SPL RLL Z33B fits 2003-2008 Nissan 350Z (Z33) and 2003-2007 Infiniti G35 Coupe and Sedan (V35). Verify your specific year and body style against the fitment table before ordering.

Is the SPL RLL Z33B street legal?
Yes. The SPL RLL Z33B is a suspension alignment component that does not affect emissions or safety systems. It is appropriate for street use in all 50 states. A professional wheel alignment is required after installation.

How do I adjust camber without jam nuts?
Loosen the titanium clamp hardware, rotate the chromoly double adjuster to change the arm length, then retighten the 360-degree rotating clamps. Adjustment can be performed on the car and requires only a hex wrench.

What other SPL Parts should I pair with the SPL RLL Z33B?
For a complete rear alignment system, pair the SPL RLL Z33B with the SPL RTA Z33 toe links, SPL RML Z33 mid links, and the SPL EL Z33 eccentric lockout kit. The lockout kit eliminates the factory eccentric bolt to prevent alignment drift under hard cornering loads.

Does installing the SPL RLL Z33B 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.

What is the difference between the billet version and the dogbone version?
The dogbone-style arm is a simpler design suited for stock spring/shock setups. The billet version (SPL RLL Z33B) is machined from solid 6061-T6 aluminum and is designed for true coilover conversions where sway bar end link clearance is required. Both provide the same quality FK rod ends and adjustment hardware.

Installation Instructions

1. Safely raise and support the vehicle on jack stands; remove the rear wheels for access.
2. Record the current rear camber measurement or photograph the OEM arm position.
3. Remove the OEM rear lower camber link mounting hardware and set the arm aside.
4. Place the SPL RLL Z33B next to the OEM arm; pre-set the double adjuster to match OEM center-to-center length with equal thread engagement on both ends.
5. Install the SPL RLL Z33B with OEM or supplied hardware; snug only until the vehicle is at ride height.
6. Lower the vehicle to ride height and torque all mounting hardware to factory specification.
7. Tighten the 360-degree rotating clamps with the titanium Allen screws to lock the adjuster in place.
8. Have the vehicle professionally aligned on a four-wheel alignment rack before driving.
