We are pleased to announce that R & M Automotive in Rockvale p is able to provide re-manufactured replacement engines for the Toyota 1GR-FE gas engine line through our JASPER Engine partnership!   This 4.0L, Dual OHC, Single VVT, V6 engine, is available for the following Toyota engine applications: 2003-2015 (4Runner | Tacoma | FJ Cruiser | Tundra). 

“JASPER replaces the OE cast aluminum pistons with forged aluminum pistons of our own design,” says Brad Boeglin, JASPER New Product Development Group Leader.  “The JASPER-engineered pistons have a 38% larger oil return area. This is coupled with the use of a two-piece oil ring design, replacing the three ring design of the OE piston. These two changes improve oil control, and prevent the oil rings from sticking.”

“In addition, the JASPER-engineered piston has a profiled top ring land to reduce scuffing under high-load, and an anodized crown for higher heat strength and top ring stability,” said Boeglin. “Our specially-designed pistons utilize a wider graphite coated skirt to prevent dry startup piston scuffing,” added Boeglin. “We've also improved the skirt profile for greater piston stability.”

The JASPER re-manufactured Toyota 1GR-FE is covered by a 3-Year/100,000-Mile nationwide, transferable, parts and labor warranty. Full warranty disclosure is available upon request.
