Spring Under Axle Perches for 3", 3.25," 3.5" Axle Tubes Heavy-duty perches built for extreme flex. These fully-boxed spring perches are engineered specifically for spring-under-axle applications where maximum flex is critical. Born from desert racing needs, they're built strong enough to handle extreme suspension travel while staying compact at just 4 3/4" long to avoid limiting flex. Perfect for high-performance builds where you need bulletproof mounting without compromising suspension movement. Constructed from 3/16" steel in a fully-boxed design for maximum strength-to-weight ratio. Available for 3", 3.25", or 3.5" axle tubes with 2.5" spring width. CNC precision ensures perfect fitment every time.
