The GPM SB170R/L rear L-shape shocks are presented as a matched pair engineered for rear replacement on the Team Losi SUPER BAJA platform, intended to provide more stable damping and increased service life. They target common failure points through dimensional changes while maintaining scale appearance.
Technical highlights drawn from the source information include an increase in coil wire thickness to 2.5mm for a firmer spring rate and a move to a 7mm shock shaft to minimise bending under load. The aluminium cylinder is described as light and robust, the sealed spring retainer reduces oil loss, and the L-shape collar lengthens the oil travel path to stabilise damping characteristics. The midpoint measurement from ball-top to ball-end is 170mm.
Professional fitting and tuning notes: these shocks are designed to replace rear units on compatible Super Baja kits using L-shape ball-post geometry and the specified 170mm midpoint. Install by removing the original rear shocks, attaching the ball-ends to shock towers and lower arms, then refine preload and damping settings iteratively to match vehicle mass and surface conditions. Inspect seal seating, shaft alignment and travel limits during setup to ensure long-term reliability.
For builders seeking a durable rear shock option that reduces shaft flex and improves oil containment, these aluminium L-shape units are a practical upgrade for consistent rear-end performance.
