SK689R36JP2-6.75W-1.625
Upgrade your Jeep Wrangler JL (2018–2023) with this custom PSC Cylinder Assist™ Steering Kit designed specifically for 6.75″ axle stroke and 1.625″ OD tie rod clamp—ideal for Teraflex Terra44 or similar aftermarket steering setups.
This premium bolt-on system dramatically improves steering performance, durability, and precision for off-road builds using oversized tires or lockers. It includes:
-
Big Bore XD Steering Gearbox: Upgrades the factory 70 mm hydraulic piston to 80 mm and transitions the sector shaft from 42 mm to a robust 45 mm for superior torque delivery and strength
-
High-flow Belt-driven Pump & Reservoir: Replaces the stock EHPS pump to prevent overheating during trail use, offering consistent hydraulic pressure when you need it most.
-
CAK689R‑6.75W Cylinder Assist Axle Kit: Designed for 6.75″ lock-to-lock stroke, this axle-mounted cylinder reduces steering effort and improves on-center feel
-
1.625″ Tie Rod Clamp (TRCL1.625): Compatible with Terra44 aftermarket tie rods, allowing seamless integration without the need for welding or fabrication
-
Complete hardware package: Includes hoses, fittings, cooler, anti-splash valve, SWEPCO hydraulic fluid, and a new pitman arm for a seamless installation.
This complete system replaces the factory EHPS arrangement to deliver reliable, heavy-duty steering. Built to work with your Jeep’s OEM steering geometry, the kit avoids modifications for most builds. It acts as a dynamic stabilizer, significantly reducing driver fatigue on long trails or rock crawls.
