The EvaResto Premium Rear IRS Air Suspension Kit.

For Independent Rear Suspension types, found on US Spec '68 and onwards Type 1 cars, semi automatic cars, 1302/3 Super Beetle and any other T1 car converted to IRS style suspension with stock type trailing arms. 

Following the design ethos of our Popular Swing-Axle kit, our new Bolt-On kit for IRS style/type suspensions delivers you full drop, the best possible lift, ride quality, easy fitment, quality design with proper low-stress engineering, and longevity. 

Designed with everybody in mind, and to deliver the best bolt-on low possible if you're looking for a completely non-intrusive fit... And also to work with clearance'd or modified setups (example being: Removal of bump stop mounts and leading edge of spring plate mounting flange, common modifications to allow more travel on IRS cars).

Designed to give you everything you need for full low laying air suspension straight out-of-the-box for the rear of your T1 car, with unmatched quality and value for money.

Want real lows and real driveability? Air is the way to go, and EvaResto offers only the highest quality and best performing kits on the market. The ultimate in aircooled air suspension technology.

When we set about the lengthy design process for our new Premium IRS rear air suspension system, absolutely everything was considered. Ease of fitting, clever and sturdy design, unrivalled performance, unbeatable quality, Value-for-money and of course, great visual looks (it matters!).

The Eva Premium Rear air suspension kit is designed from scratch to give no-compromise lows, full suspension range, great performance and a straightforward no-body-mods fit - straight out of the box, with zero 'add on' parts necessary!

So, what makes up our premium rear system? 
At the heart of the EvaResto Premium rear kit is our top mount brace, that not only provides a super strong mount for the Twin-Bellow air bags, but actually acts as a chassis stiffener essentially tying together 6-points of the stock VW swing axle chassis. In doing this, load and suspension weight is safely spread through your stock chassis, and no components are over-stressed or depended on too heavily. 
The smart design positions the air bag/spring in the ideal position for the best lift, drop and ride quality whilst using a compact style air bag the same as our other rear kits. Super stiff lower mount design ensures absolutely nothing is over-stressed or subjected to any more wear than an otherwise stock setup.

Clever design and proper positioning/geometry of the air bags makes for great lifting & operating pressures. Up to 5" of travel is possible with lifting starting as low as 25psi! No oversize overpowered bags to make up for poorly designed brackets/geometry, the bags we use are perfectly spec’d for the weight and application, and work seamlessly. 

Supplied with the kit is our new FreeRoll extended drop plates, which allow the torsion bars to be removed totally and the suspension reach 'full drop' without hangups on the bump stop mounts or shock tower castings.These are almost identical to our regular drop spring-plates, however feature a smooth-bore spline stub. The Stub is also machined to OE sizes, so your stock rubber bushings can be re-used.

The ride quality and handling with this kit is improved over stock, and any 'skittish' feel of a lowered rear end is totally eliminated. The supplied shock absorbers are a perfect match this setup, and body roll is kept to a minimum. Be prepared for a far more ‘sporty’ and planted feel to your VW! 

No extra wear parts (bushings, pivots etc) are introduced over a stock setup, so no extra maintenance/replacement of parts down the line is required once this kit is fitted. 

Fitting the Eva Premium rear system has been made as straightforward as possible, with zero compromises. Our prime goal is to make your experience with our parts as easy and satisfying as possible, so ease of fitting was a very important consideration during the design process. No engine or gearbox removal is necessary, and the kit can be fitted with ease in around a few hours. The kit is also supplied with a complete fastener set and detailed fitting guide.
