The 6-1\/8\" collar with 26-9\/16\" bar is the specific spec for 1968–1971 Type 1 and certain Type 3 applications. Get it wrong and the plates won't bolt up.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWhat's the difference between this part and #18-1075-0?\u003c\/b\u003e Both use the 6-1\/8\" collar with the 26-9\/16\" torsion bar, but they're geometrically tuned for different application years. #17-2674-0 is for 1968–1971 Type 1 and Type 3. #18-1075-0 is for 1972–1979 Beetles. Match to your specific year.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWill I need an alignment after installing?\u003c\/b\u003e Yes. Any change in rear ride height changes rear camber and toe. After any adjustment, get the car aligned to factory spec or to your build's chosen alignment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWhy replace the dual spring plate setup?\u003c\/b\u003e Factory dual spring plates work but are limited in ride-height options — you can only set them at discrete spline positions. The single-piece adjustable plate gives you continuous adjustment. It's also more durable in performance applications, where the factory dual setup can develop play between the two plates.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCan I install these myself?\u003c\/b\u003e Moderately involved. Torsion housing has to be opened, plates swapped, torsion bars re-engaged, everything reassembled and aligned. Plan 2-4 hours for someone familiar with VW rear suspension.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHow much ride height adjustment do I get?\u003c\/b\u003e Continuous adjustment within the mechanical range — typically 2-4\" of vertical adjustment depending on starting position and how the rest of the rear suspension is set up.\u003c\/li\u003e\n\u003c\/ul\u003e\u003chr\u003e\u003ch3\u003e\u003cb\u003eExplore Related Categories\u003c\/b\u003e\u003c\/h3\u003e\u003cp\u003eShop more parts for your build: \u003ca href=\"\/collections\/vw-beetle\"\u003eVW Beetle\u003c\/a\u003e \u003ca href=\"\/collections\/vw-type-3\"\u003eVW Type 3\u003c\/a\u003e \u003ca href=\"\/collections\/suspension\"\u003eSuspension\u003c\/a\u003e\u003c\/p\u003e","brand":"EMPI","offers":[{"title":"Default Title","offer_id":44899667771507,"sku":"17-2674-0","price":192.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/2760\/1523\/files\/17-2674-0-500x376.jpg?v=1777273211","url":"https:\/\/www.washburnsmetal.com\/products\/empi-adjustable-irs-spring-plates-6-1-8-collar-1968-71-type-1-3-17-2674-0","provider":"Washburn's Metal","version":"1.0","type":"link"}
