The Win brand is similar but stronger than the original! The Miller numbers are listed repair manuals. The 3747-13 (like Miller 8516 or 8516A). It's a specialty tool to remove and install rocker arms safely without damage to the camshaft or camshaft lobes.

Question - What's the difference between the Miller 8516A and the Win 3747-13, they look practically the same?

Answer - The Win 3747-13 is very similar to the 8516A. It works in applications when the 8516 is called for. The Win Tool is stronger and works just like the Miller 8516A, at a lower cost. The 3747-123 has more function since it can be used to change broken valve springs or just to install replacement rockers or lifters. That's why many customers choose the Win 3747-123 because it can be used when a 8426, 8387 or 8516A is needed.

Question - Can I just use a "universal" valve spring compressor to do the same thing?

Answer - No. We have searched with all of our suppliers to find a universal type valve spring compressor and there's not one available that works for 3.7 and 4.7 Mopar engines. The best tool for doing rocker arm replacement, valve spring replacement, cam swaps etc is the Win 3747-123 that can be used when a Miller 8426, 8387 or 8516A is called for in a service manual. The Win 3747-123 offers a much lower cost alternative.

Question - Does this rocker arm remover work on Pentastar 3.6 engines?

Answer - No. There is not one made for the 3.6 Pentastar engine. The design does not allow. Shops typically purchase the Pentastar Combo kit, which includes timing chain holders, phaser locks and a crank holder, to save time from disassembling the front of the engine. See the product by clicking the following Pentastar Combo.

Question - Can this be used on a 2003 Dodge Durango 4.7 liter engine? Can be used on the vehicle?
