Product Description
Detroit Speed’s Short Long Arm (SLA) Suspension Conversion redefines Fox Body handling with a no-compromise double wishbone design. This system replaces the outdated factory suspension with modern geometry, increased strength, and race-proven adjustability, delivering premium fit, finish, and performance.
SUPERIOR SUSPENSION GEOMETRY & STABILITY
Detroit Speed’s exclusive frame rail insert optimizes camber gain and roll center height, significantly improving front-end stability. The tubular upper and lower control arms reduce deflection, providing precise suspension movement and sharper handling response.
FORGED UPRIGHTS & EXPANDED BRAKE OPTIONS
Lightweight forged aluminum uprights feature modern hubpack bearings for durability and reduced maintenance. Designed to work with S550 Mustang (2015-2024) brake systems, this setup provides access to high-performance braking solutions for superior stopping power.
HIGH-PERFORMANCE COILOVER CONTROL
Detroit Speed/JRi non-adjustable aluminum coilovers feature Detroit Tuned valving, delivering precision damping. Paired with a 1-7/16” diameter sway bar, this system provides optimized handling and stability for both street and track applications.
MAXIMIZED TIRE CLEARANCE
Designed for serious performance applications, this system allows clearance for 275/35R18 tires on a 10” rim while maintaining full steering lock. Whether on the street or track, this setup ensures maximum grip without compromise.
