Peak Suspension 2.5" DSC Coilover Summit Kit | 2025+ Toyota 4Runner & Land Cruiser 250

Adding gear, armour, or larger tires to Toyota's TNGA-F platform quickly overwhelms factory shocks, causing oil overheat, shock fade, and loss of control on washboard roads or technical trails. The Peak Suspension 2.5” DSC Coilover Summit Kit replaces soft stock dampening with fully adjustable, rebuildable performance components engineered specifically for heavy trail use. Featuring Dual Speed Compression (DSC) adjusters, remote reservoirs, and heavy-duty upper control arms, this kit gives you total command over your ride quality without requiring permanent frame modifications. Key Features Dual Speed Compression (DSC) Adjustability: Independent high-speed and low-speed compression dials allow you to tune for harsh high-velocity impacts separately from low-speed body roll and brake dive. Thermal Endurance: High-flow 2.5” shock bodies and remote reservoirs significantly increase oil capacity, keeping shock temperatures down during continuous runs on BC Forest Service Roads or rough desert tracks. Corrected Suspension Geometry: Included Peak tubular upper control arms restore proper caster angles and wheel position after lifting, maintaining clean highway tracking and full droop travel. Secure Preload Adjustment: Built with a pinch-bolt coil collar that locks your ride height in place without galling or damaging the aluminum coilover threads. Vehicle-Specific Tuning: Internal valving is tuned directly for the weight distribution and dynamic motion of the 6th Gen 4Runner and LC250 platforms.

We always install upgraded upper control arms on shop builds at this height to retain proper alignment specs and prevent upper ball joint binding during full articulation.
