This ProForm checker is made from heat-treated chromoly for strength and is finished with black oxide to resist corrosion. Sold individually, it fits into standard lifter and rocker locations so you can measure and compare pushrod lengths during mock-up and final assembly.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this tool ensure correct pushrod length?\u003c\/h3\u003e\n\u003cp\u003eThe tool provides a single reference length in the range of 7.500–8.700 inches to verify that installed pushrods allow proper rocker geometry and valve motion. Use it in place of a pushrod while positioning the rocker and checking for contact and travel. Because it's manufactured from chromoly, it holds straightness and dimension under workshop conditions.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eLength range: 7.500 to 8.700 inches for common pushrod applications\u003c\/li\u003e\n  \u003cli\u003eChromoly construction maintains dimensional stability\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish adds corrosion resistance for longevity\u003c\/li\u003e\n  \u003cli\u003eSingle-piece design for easy insertion and removal during mock-up\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the physical specs and package details?\u003c\/h3\u003e\n\u003cp\u003eThe tool ships individually and is compact for easy storage in a toolbox or parts tray.

Professional engine builders, experienced hobbyists, and performance tuners who need a dependable, single-length reference for pushrod validation will benefit most. If you frequently mock up cylinder heads, swap valvetrain components, or verify rocker geometry, this ProForm chromoly checker offers a compact, corrosion-resistant way to speed accurate setups without guessing lengths. It’s especially useful when working with small-batch or custom pushrods where one reliable reference tool streamlines repetitive checks.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What length range does the ProForm checker cover?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It covers pushrod lengths between 7.500 and 8.700 inches to verify common valvetrain setups.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is the checker corrosion resistant?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the chromoly construction has a black oxide finish for added corrosion resistance.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"ProForm","offers":[{"title":"Default Title","offer_id":48086139797662,"sku":"B007KXIGLU","price":45.08,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/proform-pushrod-length-checker-front-view.jpg?v=1785886339","url":"https:\/\/northtrailauto.ca\/products\/proform-pushrod-length-checker-7-500-8-700-in-chromoly-black-oxide-single-reference-tool-for-accurate-rocker-geometry","provider":"North Trail Auto","version":"1.0","type":"link"}
