The Cognito Camber Adjustable Front Lower Control Arms for the RS1 are designed to be direct OE replacement. The OE lower arms are known to be a weak link and one of the first suspension upgrades needed. The heavy-duty high clearance design allows for better ground clearance while maintaining superior strength. Typical adjustable control arms use a threaded rod end which doesn't offer fine camber adjustment. Cognito has engineered an ingenious solution that uses a bolt-on uniball rod end which is shim-able for fine camber tuning. Simply unbolt the rod end from the control arm and add or remove the supplied shims to get your desired camber angle. Each Kit Features: Direct OE replacement Significantly stronger than stock Patent pending fine camber adjustable design Replaces weak ball joints with uniballs Can be used in a double shear spindle application High clearance design increases ground clearance Heavy duty pivot bushings High-grade steel construction Durable semi-gloss black powder coat Made in the USA
