Show original supplier description
The RalliTEK adjustable rear lower control arms are engineered as a direct replacement for the OEM components on 2013-2023 Subaru Crosstrek models. They are built to withstand rigorous trail use, having been tested and proven on 4x4 trails. Constructed from durable 3/16” thick laser-cut steel, these control arms undergo a dual-process powder coating for superior corrosion resistance. They are MIG welded for enhanced strength and feature an exclusive design incorporating a high-strength, off-road type sealed Johnny Joint, which is significantly more robust than OEM connections. Key features include a rear lower fitment location, powder-coated finish, adjustable camber tuning, and compatibility with both lifted and OEM height vehicles. The product is sold in pairs and comes with a lifetime warranty, and is proudly designed, assembled, and made in the USA. Installation is estimated to take 1 hour with a DIY difficulty rating. Note: This product is intended for off-road use only. Fitment is guaranteed for USDM models only. Non-USDM vehicle owners should contact RalliTEK for compatibility checks.
