Coil springs for front axle weight up to 4,300 lbs. Eliminates troublesome airbags, restores ride height, improves handling. For P-Chassis Class A motorhomes 1968-2007.
A chassis manufacturer has no way of knowing what body will be placed atop its chassis, how much it will weigh, or where that weight will be placed. As a result, some motorhomes built on the Chevy/Workhorse P30/P32 chassis don't have even weight distribution. This can result in listing, harsh ride, excessive sway, porpoising, dynamic changes in toe (alignment), and accelerated tire wear.
The SuperSteer SS250 coil springs are manufactured to match the exact weight of YOUR motorhome, thereby restoring correct ride height, proper suspension geometry, and ride quality. The factory often used weak springs supplemented with troublesome airbags inside the coil springs - a band-aid solution that leads to air leaks and maintenance headaches. With SuperSteer coil springs custom-matched to your front axle weight, you can eliminate the use of airbags inside your coil springs entirely.
The exact weight of your coach is determined (through weighing at a truck scale), then the proper spring is matched to that particular weight. This "tailor-made" approach allows your shocks to work better for a smoother ride, helps prevent excessive front suspension travel that produces alignment changes and side scrub, and gets your coach on its proper suspension geometry with correctly set ride height.
Tailor-made for your exact front axle weight - choose from 4,000, 4,100, 4,200, or 4,300 lbs
No more troublesome airbags inside coil springs that leak and require maintenance
Returns your motorhome to proper suspension geometry and correct ride height
Stops excessive suspension travel that causes alignment changes and tire wear
The Chevy/Workhorse P30 and P32 chassis featured an independent coil spring front suspension - different from the Ford F53 or later Workhorse W series. While this design provided a smoother ride, it created challenges:The Factory Problem: Chassis manufacturers had no way to know what coach body would be installed or how much it would weigh. They used generic springs that often couldn't handle the actual weight, leading to sagging, bottoming out, and poor handling. Their solution? Install helper airbags inside the coil springs - a band-aid fix prone to leaks and maintenance issues.The SuperSteer Solution: Instead of using one-size-fits-all springs with troublesome airbags, SuperSteer manufactures coil springs in precise weight ratings. The SS250 covers lighter P-chassis motorhomes with four weight options from 4,000 to 4,300 lbs in 100 lb increments. You weigh your coach's front axle under normal traveling conditions, then order springs matched to your actual weight.The Benefits: With properly rated springs, your suspension operates in its optimal geometry range. This allows shocks to work correctly, prevents excessive suspension travel that causes alignment changes, eliminates bottoming out and topping out, reduces sway and body roll, extends tire life, and provides a dramatically better ride.
DO NOT guess your front axle weight. You MUST weigh your motorhome.Weigh under normal traveling conditions:• Full fuel tank• Full water tanks (or typical travel level)• Normal number of passengers• Typical cargo and suppliesWhere to weigh:Find a CAT Scale location or ask your RV service center if they can weigh your coach.We match springs to ACTUAL front axle weight, not GAWR:The GAWR (Gross Axle Weight Rating) on your sticker is the MAXIMUM your axle can handle - not your actual weight. Ordering based on GAWR instead of actual weight will result in springs that are too stiff for your coach.Round to nearest 100 lbs:If your front axle weighs 4,075 lbs, order the 4,100 lb springs.If your front axle weighs 4,025 lbs, order the 4,000 lb springs.
Professional Alignment Required:After installing new coil springs, you MUST have a professional alignment performed. The new springs will change your ride height and suspension geometry, affecting alignment.Do Not Order Higher Rated Springs:We do not recommend ordering springs rated higher than your actual front axle weight. This will result in too harsh of a ride. Always match springs to your actual weighed front axle weight.Installation Time:Approximately 3 hours for the set. Professional installation recommended if you're not experienced with suspension work.Download the SuperSteer SS250 Coil Springs Installation Instructions
The SS250 part number includes springs for four different weight ratings:4,000 Lbs - For front axle weight 3,950-4,050 lbs4,100 Lbs - For front axle weight 4,050-4,150 lbs4,200 Lbs - For front axle weight 4,150-4,250 lbs4,300 Lbs - For front axle weight 4,250-4,350 lbsNeed a different weight range?SuperSteer offers additional spring part numbers for heavier front axles:• SS255: 4,400-4,900 lbs• SS260: 5,000-5,300 lbs• SS265: 5,400-5,900 lbs• SS268: 6,000-6,500 lbs
The Factory Compromise:Chevy's solution to inadequate factory springs was installing helper airbags inside the front coils. While this raised the front end, it created new problems: air leaks, maintenance issues, and inconsistent ride quality depending on airbag pressure.The SuperSteer Difference:By manufacturing springs in precise weight increments, SuperSteer eliminates the need for airbags entirely. Your suspension operates as designed, with proper spring rates for your actual weight. This means better ride quality, improved handling, longer tire life, and no more airbag maintenance.Part of Complete P-Chassis Upgrade Path:SuperSteer developed the SS250 coil springs as part of a comprehensive solution for P30/P32 chassis handling issues. Consider combining with:• P3032 Bell Crank (reduces steering play)• SS29132 Adjustable Draglink (improves steering precision)• Safe-T-Plus Steering Control (adds stability)• SS300U Rear Trac Bar (eliminates rear axle side shift)
The SuperSteer SS250 coil springs fit Chevy and Workhorse P30 and P32 chassis from 1968 to 2007.
Note: The P30 and P32 chassis featured independent coil spring front suspension, different from the Ford F53 or later Workhorse W series.
