Complete Your Pro XP 4-Seat Portal Gear Lift Build — Spring Kit Engineered for PGL Suspension Leverage

Stop running stock springs on your portal gear lift — they're not rated for the leverage your PGL creates on a 4-seat chassis. The AllThingz UTV Portal Gear Lift Spring Kit Upgrade for the Polaris RZR Pro XP 4 Seater is engineered specifically for Pro XP 4-seat models running aftermarket portal gear lifts. When you install a portal gear lift, you extend the lower shock eyelet — which adds leverage to the spring. A stock-rated spring will feel too soft under this added leverage, causing the machine to sit lower than factory height and feel wallowy at speed. The 4-seat chassis adds additional weight that's factored into the spring rate calculation. This kit uses heavier-rated front springs specifically calculated to counter that added leverage, returning the machine to factory ride height and factory ride quality — with the superior spring construction of an AllThingz UTV kit. Adds 2–3 inches of ride height. Free shipping. 100% money back guarantee.

Why Pro XP 4-Seat Portal Gear Lift Builds Need This Kit

• Counters Portal Gear Lift Leverage — Heavier-rated front springs specifically calculated to offset the added leverage from the PGL lower shock eyelet extension
• 4-Seat Chassis Weight Factored In — Spring rates account for the additional weight of the 4-seat Pro XP chassis vs. the 2-seat version
• Returns Machine to Factory Ride Height — PGL with stock springs sits too low; this kit corrects it
• 80%+ Ride Quality Improvement — Superior spring construction over stock, even at the heavier rating
• Front-Only Upgrade (Rear Not Required) — Rear trailing arm is made wider, not longer — wider doesn't create leverage, so rear OE lowers + AllThingz tenders are sufficient
• 2–3" Additional Ride Height — On top of correcting the PGL leverage sag
• Maintains Factory Suspension Geometry — Correct spring rate ensures geometry is preserved with PGL installed
• Multiple Powder Coat Colors — All colors coated in-house at AllThingz UTV's facility

Why Portal Gear Lifts on a 4-Seat Pro XP Require Their Own Spring Kit

A portal gear lift raises the axle centerline by extending the lower shock eyelet — creating additional leverage on the spring. The 4-seat Pro XP carries significantly more chassis weight than the 2-seat version, which means the spring rate required to counter PGL leverage is different. Using a 2-seat PGL kit on a 4-seat chassis results in a spring that's too soft under the combined weight of the heavier chassis and passengers. The AllThingz UTV Portal Gear Lift Spring Kit for the Pro XP 4-seat is engineered with front springs rated specifically for the 4-seat chassis weight and the PGL leverage calculation. The rear trailing arm is made wider, not longer — so the rear OE lower springs remain correct and only rear tender springs are needed.

Installed portals on my Pro XP 4-seat and the stock springs felt terrible. This PGL spring kit fixed everything — back to factory height with dramatically better ride quality for the whole crew. — Verified Buyer

Make sure you get the 4-seat version — the spring rates are different from the 2-seat PGL kit. Installed perfectly and the difference is immediately noticeable. — Verified Buyer
