GPM Racing Aluminium Rear Lower Trailing Arms - 24pcs Set for Losi 1/6 Super Baja Rey 4x4 (SB014L)

Precision 6061 T6 rear lower trailing arms for LOSI applications

This CNC machined upgrade replaces the rear lower trailing arms on the LOSI SUPER BAJA REY 1/6 4WD chassis to deliver improved rear mounting rigidity and consistent damper geometry. Main components are machined from 6061 T6 aluminium with hollowed sections to reduce mass while retaining torsional stiffness. Stainless steel ball ends and stainless fasteners are specified to provide durable joints and corrosion resistance appropriate to scale outdoor running.

The kit is supplied as a 24 piece assembly containing the trailing arms and matched hardware for direct installation and tuning. Multiple pre-drilled mounting positions on each arm permit step changes to damper tilt and roll-bar link geometry, enabling precise adjustments to rear roll behaviour and shock leverage without modifying shock housings.

• Included items in set: rear lower trailing arms (2 pcs), stainless steel round head screws 4×32.5 (4 pcs), 4×25 (2 pcs), 4×22.5 (2 pcs), white POM collars 4×15.5×4.2 (4 pcs), white POM collars 4×15.5×6.6 (2 pcs), stainless steel lock nuts 4mm (8 pcs).
• Material highlights: aluminium 6061 T6 main arms, stainless steel ball ends and fasteners, POM collars for controlled spacing and tilt settings.
• Design notes: hollow machining reduces mass while maintaining section rigidity; screw-lock retention secures the stainless ball ends for reliable service life.

Recommended damper tilt settings using the supplied POM collars:

• Baseline tilt: install one 6.1mm collar outward on the damper ball end.
• Approx 5 degree outward tilt: install two 4.2mm collars, one each side of the damper ball end to produce outward lean.
• Approx 10 degree outward tilt: install one 6.1mm collar inward on the damper ball end to increase outward lean.

Compatible Models

• LOSI 1/6 4WD SUPER BAJA REY 4X4 1.0-LOS05013

This 24 piece aluminium rear lower trailing arm set is intended for owners of the LOSI SUPER BAJA REY 1/6 4WD who require firmer rear mounting and repeatable damper angle adjustments without altering shock assemblies.

What hardware and counts are included?

The kit includes two CNC machined arms and the listed stainless fasteners and POM collars: three screw lengths, collars and 4mm lock nuts totalling 24 pieces for assembly.

How does the hollow machining affect performance?

Hollowing reduces unsprung and rotating mass while keeping necessary section stiffness, improving responsiveness without compromising durability.

Are these arms a direct replacement for stock parts?

They are manufactured to match the LOSI SUPER BAJA REY mounting pattern shown in the compatibility box; verify fit against your chassis before fitting.

What is the recommended method for tilt adjustment?

Use the supplied POM collars in the positions described to alter effective ball position and damper lean; this provides stable, repeatable tilt steps without modifying the shock body. Write Product Review Please sign in your account before you can write any review. Sign In Close
